The Role of the Supramolecular and Electronic Structure in the Performance of Molecular Diodes
Prof. Christian A. Nijhuis , Chemistry Department, National University of Singapore
http://staff.science.nus.edu.sg/~christiannijhuis/index.html

Understanding the mechanisms of charge transport across molecules, or self-assembled monolayers, is important in organic based photovoltaics, OLEDs, energy storage, bio-electronic devices, etc. Physical-organic studies that connect the supramolecular structure of the device to de ... more

Frontiers of Entangled Photons in Quantum Imaging and Quantum Communication
Prof. Dr. Anton Zeilinger, University of Vienna & Austrian Academy of Sciences

Entangled photons can now routinely be used in quantum communication over large distances exceeding 100 kilometers. I will review recent experiments, particularly in quantum teleportation and entanglement swapping on the Canary Islands. A novel possibility is given by photon stat ... more

Quantum Dots on a Knife’s Edge: Plasmonic Wedge Waveguides and Resonators with Integrated Quantum Emitters
Prof. Dr. David J. Norris, Optical Materials Engineering Laboratory, ETH Zurich, Leonhardstrasse 21, 8092 Zurich, Switzerland

Quantum optics involves the coupling of quantum emitters to their electromagnetic environment. Because this coupling is related to the concentration of the optical field, it is typically constrained by the diffraction limit of light. One way to circumvent this is by moving to qua ... more

From STED Microscopy to STED Lithography
Prof. Dr. Thomas A. Klar, Institut für Angewandte Physik, Johannes Kepler Universität Linz, Österreich

In 1873, Ernst Abbe has found that resolution in microscopy should be limited to a third of the wavelength.[1] This so called diffraction limit kept its dogmatic character for about 130 years, which is surprising because modern quantum chemistry and quantum optics, which were ful ... more

From thin film growth in plasma-enhanced chemical vapor deposition to interface engineering in (plasma-assisted) atomic layer deposition
Dr. Mariadriana Creatore, TU Eindhoven, Department of Applied Physics, Plasma and Materials Processing group

This colloquium will review the main features of plasma-enhanced and plasma–assisted deposition methods in terms of gas phase production of reactive species at low thermal budget and control in thin film growth and interface engineering. Two case-studies will be addressed, bo ... more

Interaction of Ferromagnetic and Superconducting Permanent Magnets – Superconducting Levitation
Prof. Dr. Ludwig Schultz, Leibniz-Institut für Festkörper- und Werkstoffforschung Dresden (IFW Dresden)

New means of urban transportation and logistics will become realistic with superconducting magnetic bearings using bulk high temperature superconductors. The advantage of superconducting magnetic levitation is that it works passively stable without any electronic control but with ... more

Advanced transmission electron microscopy for the development of high‐efficiency solar cells
Prof. Dr. Wolfgang Jäger, Institute for Materials Science, Christian-Albrechts-University of Kiel

Highly efficient multi-junction solar cells based on III-V compound semiconductor materials are applied for power generation in terrestrial concentration photovoltaics and in space applications. Solar-electric conversion efficiencies well above 40% have been obtained for concentr ... more
