Schaadt Group, Technische Universität Clausthal

The group of Prof. Daniel Schaadt works on metallic nanostructures and III-V semiconductor heterostructures for application in a variety of fields, such as spintronics, photovoltaics and detection of cosmic UV-radiation. A strong emphasis is given to the growth of III-V heterostructures on novel substrates, such as pre-patterned substrates for controlled growth of InAs quantum dot, or LiGaO2 and m-plane SiC to obtain nitrides structures without intrinsic field in the growth direction. The group operates for these purposes two molecular beam epitaxy systems, one for arsenides and one for nitrides. For spintronic applications, the group investigates Cu-doped nitrides, which show ferromagnetism at room temperature. To obtain better UV detectors for space applications, the group investigates the direct growth of nitride layers on glass substrates. Prof. Schaadt is one of the pioneers in the field of plasmonic solar cells, where plasmon resonances in metallic nanoparticles are used to increase the absorption in Si solar cells. The group is currently applying this concept to group III-arsenide based concentrator solar cells, where tailored metal nanoparticles are prepared by chemical synthesis and are immobilized on III-V solar cells.
