Catalysis Success at Transregio
[27.05.2022] Extension of a Collaborative Research Center/Transregio: The German Research Foundation (DFG) is extending the existing TRR on catalytic materials and processes for another four years.
In contrast to a classical Collaborative Research Center (SFB), a Collaborative Research Center/Transregio (TRR) is jointly applied for and supported by two or three universities. The UDE is significantly involved in the extended SFB/TRR:
Targeted design of new catalyst materials
Almost all everyday objects come into contact with at least one catalyst during their production to make production cheaper, more environmentally friendly or even possible in the first place. The development of inexpensive, highly active and selective catalysts at the atomic level is the goal of SFB/TRR 247 "Heterogeneous Oxidation Catalysis in the Liquid Phase". Following its successful first funding phase, it is being extended by the DFG for a further four years period and funded with 12.3 million euros. The researchers are now focusing on identifying active centers of the materials and understanding reaction mechanisms in detail. The Department of Electronic Materials and Nanostructures is involved in this with a project. In this project, optical spectroscopy is used to investigate catalytic processes.

[09.02.2022]
The WISNA-Juniorprofessor Franziska Muckel has been portraited as a Research Talent of the UDE. In this online series the UDE introduces young and up-and-coming researchers of various disciplines. In a three-part video series, Franziska Muckel discusses what’s crucial for material development, why she has returned to the UDE and that she initially planned to work on a ship rather than in the lab.
Crystallographic Insights by Optical Spectroscopy on the Nanoscale
[07.02.2022]
Being 10.000 times smaller than a human hair, they have the potential to revolutionize the world of light emitting devices: Semiconductor crystals from a novel semiconductor material – so-called perovskites – with sizes of only few nanometers promise record efficiencies, outstanding stability, and unprecedented scalability. Scientist of the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) and collaborators have now found a way to determine the crystallographic properties of such nanocrystals using solely spectroscopic methods – featured in the journal “Nano Letters”.
Despite setting countless records in the fields of photovoltaics and light emission for several years, the microscopic origin of the outstanding properties of the perovskite semiconductor material class is still subject of lively scientific debates to date. Scientists at the chair for „Electronic Materials and Nanostructures“ collaborate with a partner group at the ETH Zurich to investigate the optical properties of tiny perovskite crystals, so-called quantum dots, and their correlation with the atomic structure of the semiconductor material.
In a recent publication, the group demonstrated the determination of the atomic crystal structure of asymmetric nanocrystals with dimensions of only 10x3 nanometers by purely analyzing the light emission of the crystals. This direct connection, which does not hold in classical semiconductors and symmetric nanostructures, enabled detailed insights into the correlation between the atomic structure and the optical properties of the promising semiconductor. Additionally, the scientists succeeded to reconstruct the spatial orientation of individual nanocrystals from purely optical measurements, enabling the assignment of the optical signals to the respective crystal axes for the first time.
The observation of these correlations highlights the potential of such asymmetric perovskite nanocrystals to guide the scientific community towards unraveling the intriguing properties of this material system and to transfer this knowledge to potential new, and even better, semiconductor systems.

Research projects in cooperation with the University of Waterloo in Canada
[04.02.2022]
In late fall of last year, two of our scientists moved their workplace to Canada for a few weeks to carry out experiments for their PhD research.
Within the DAAD program for project-related personal exchange, the cooperation with the University of Waterloo strengthened the international network of our group. In the lively scientific exchange between the researchers on site, they worked on the continuous development of optoelectronic devices based on 2D materials. M. Sc. Henrik Myja combined different fabrications methods in order to embed 2D semiconductors in LED architectures. On the one hand, current injection layers of conducting oxides were deposited by a system for large area atomic layer deposition at atmospheric pressure (AP-SALD) in the group of Prof. Kevin Musselman. This was complemented by contact layers of silver nanowires from Prof. Irene Goldthorpe's group. With this combination, he succeeded in producing transparent LEDs.
M. Sc. Yannick Beckmann worked on the encapsulation of detectors based on 2D materials. For this, also in collaboration with Prof. Musselman's group, he deposited different oxides on his devices using AP-SALD and was thus able to significantly improve the sensitivity of his photodetectors.

Two-Dimensional (2D) Magnets
[26.01.2022]
Starting with the pereparation of graphene (an atomically thin carbon layer) in 2004, two-dimensional materials have been playing an important role in the research for electronic and optical applications. Meanwhile, more than 1000 different 2D materials have been predicted (and partly realized). In addition to graphene, isolating or semiconducting 2D materials are highly attractive for future electronic components like transistors, LEDs or solar cells.
It took until 2017 for first inspiring reports on distinct magnetic properties in pristine single layers of 2D materials. This discovery opens a complete novel field of research on 2D materials, especially since different 2D materials can be stacked in top of each other to create heterostructures with completely new physical properties.
In collaboration with Prof. Doron Naveh (Ramat-Gan, Israel), Prof. Efrat Lifshitz (Haifa, Israel) und Prof. Thomas Heine (Dresden, Germany) our group will continue the research on this trendsetting subject within a new project of the German-Israeli Project Coordination (DIP), a program by the German Research Foundation (DFG). The work will investigate heterostructures of 2D antiferromagnetic (AFM) semiconductors with valley-polarized transition metal dichalcogenides or / and 2D superconductors. We aim to control the heterostructures’ magnetic properties by tuning the strength and nature of interlayer interactions.
Research on Semiconductors Light Weakens Magic Nanoclusters
[21.01.2021]
They are known as "magic sized nano clusters" because they have special properties: The particles consist of only a few atoms, but since they are arranged in a special crystal structure, they are extremely stable. Unless you expose them to light.
Scientists from the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) have discovered that such materials undergo fundamental changes as soon as they are merely analysed using optical methods. "Nature Communications" reports on the issue.
Junior professor Dr. Franziska Muckel is head of the working group "Electroenergetic Functional Materials" at the chair "Materials of Electrical Engineering”. Her team investigates cadmium selenide particles, which consist of no more than 26 atoms. Yet these atoms are arranged in a crystal structure, i.e. in a regular lattice similar to the symmetrical climbing frames made of ropes and metal on children's playgrounds. This structure renders the particles extremely stable.
In collaboration with the Seoul National University (South Korea) and the Max-Planck-Institut für Eisenforschung in Düsseldorf, UDE's researchers demonstrated that light above a certain wavelength weakens the bonds within these semiconductor nano clusters significantly – a hundred times more than in the same material with much larger dimensions.
Optical analysis methods as standard techniques in semiconductor research thus reach their limits in these dimensions: Instead of merely elucidating material properties, they change the investigated material itself. Since magic nano clusters are an important intermediate step on the way to larger functional particles, this is a decisive discovery.
Muckel, who conducts her research at the NanoEnergieTechnikZentrum (NETZ) on the Duisburg campus, now wants to put the results to practical use: "In the long term, we plan to develop components from similar materials that convert light into charge carriers and could therefore serve as optical sensors."

Master thesis sponsored by the Stiftung Industrieforschung
[24.09.2020]
Every year, the Stiftung Industrieforschung supports students from technical and scientific studying programs throughout Germany whose master's thesis promises relevance to medium-sized industrial companies with a scholarship.
B.Sc. Henrik Myja receives one of these coveted scholarships for his thesis on "Transparent and flexible light emitting devices based on nanometer-thin 2D semiconductors" at the Chair of Electronic Materials and Nanostructures (Prof. Dr. Gerd Bacher). The active material used for the devices are large-area tungsten disulfide monolayers, which originate from a cooperation with Prof. Dr. Andrei Vescan from the RWTH Aachen University. These are investigated with respect to internal quantum efficiency and embedded in to a transparent and flexible device environment. The analysis of the devices will be used to estimate the application potential, e.g. in the field of flexible lighting or display elements for weight-reduced mobile solutions.
Creating magnetism from light!
[02.04.2020]
Generating magnetism on demand without the use of electrical currents – in the field of doped nanocrystals no science fiction anymore, but close to reality. A major breakthrough in this area was recently achieved by the group of Prof. Gerd Bacher in collaboration with the Gamelin Group at the University of Washington, Seattle.
Using spectroscopy on individual nanocrystals in a rotatable magnetic field it was shown how light induced magnetism can be purposefully directed.
In future, this work will be continued and extended with funding of the Deutsche Forschungsgemeinschaft, which has just granted a full 3 year project on this topic.

UDE researchers win LED Professional Science Award for their “Large-area white light-emission”
[28.09.2017] Dr. Ekaterina Nannen and Julia Frohleiks, who work in the junior research group “Solid State Lighting” at the “Electronic Materials and Nanostructures” group at the University of Duisburg-Essen, combined for the first time yellow LECs with blue light-emitting quantum dots. Quantum dots are colloidal nanostructures with a size of only 5 nanometers, which have exceptional physical and optical properties. The hybrid QD-LEC devices show stable white light emission while maintaining all benefits which are typical for LECs.
For this “remarkable degree of novelty”, the group was awarded with the “LED Professional Science Award” at the leading international lighting technologies event in Bregenz (Austria). The selection committee certifies the results to have a “significant impact on future research and development”.
Nanostructures for innovative lighting
[25.10.2016] Lighting-up a bag‘s interior or illuminating joggers from the darkness: Light-emitting electrochemical cells, LECs, provide significant benefits compared to the well-known LEDs, although appropriate light is still lacking. Up to now, only yellow light-emitting LECs are suitable for application, for white light at least one more color component is necessary. Researchers from the Center for Nanointegration (CENIDE) at University Duisburg-Essen (UDE) were for the first time able to modify specifically the emission color and improve the device performance of the LEC at the same time.
Julia Frohleiks, PHD student in the junior research group of Dr. Ekaterina Nannen, based her idea on semiconducting quantum dots, tiny structures which allow for quantum effects.
Digital Doping of tiny Nanocluster consisting of only 26 atoms
[2016] Doping of semiconductors (i.e. the intentional incorporation of impurity atoms) allows the precise tuning of the electrical and optical properties, representing the basis of the entire field of micro- and optoelectronics. Upon further reduction of the dimensions approaching the nanometer scale, doping becomes more and more challenging. Reaching the ultimate limit the question occurs, weather single dopants can generate new functionalities – the cutting-edge research area called “Solotronic”. Recently, scientists from the “Electronic Materials and Nanostructures”-group at the University of Duisburg-Essen together with Co-workers from the Soul National University have successfully proven that a single magnetic dopant in tiny nanoclusters – built up of only 26 atoms – generates a pronounced magneto- optical response.
Uni DUE is partner in the research network „HEA2D – Fabrication, properties and applications of 2D nanomaterials”
[01.04.2016] New materials of atomic thickness have become popular as so-called “2D materials”. The semimetal graphene or the semiconducting MoS2 are the most prominent examples. If they are incorporated into large-scale fabrication processes, they will provide integrated and sustainable solutions for new products and production strategies. Up to now, innovative devices on 2D base are still retarded by the fragmented production chain. In the framework of the joint project HEA2D a continuous production chain is explored, encompassing deposition techniques for 2D materials, procedures for transfer to foil, large-scale integration into plastic components and eventually the development of demonstrator applications.
The research at the UDE focusses on two points: First, the growth of graphene at reduced temperatures, second, the development of innovative device concepts for light emitters based on 2D semiconductors. Partners in the research network are AIXTRON SE, the Fraunhofer Institute for Production Technology, the Kunststoff-Institut Lüdenscheid, the Coating Machinery GmbH, and the University Siegen.
„HEA2D“ is financially supported by the European Fund for regional development (EFRE) 2014-2020.
