- Leading the Nanostructure Spectroscopy Group at Walter Schottky Institut of TUM: focus on understanding, manipulating and exploiting electronic, spin and photonic quantum phenomena in semiconductors and nanostructured electronic and photonic materials. Major research interests include: optical, electronic and spintronic properties of semiconductor quantum dots and wires fabricated from Aimonides, group-IV materials (Si, SiGe, C) and II-VI semiconductors and oxides (CdSe, ZnO). Another major arm of our research concerns quantum optical studies of dielectric and metallic nano-photonic materials and the application of such systems for applications in quantum information processing, metrology and sensing.

- Attaching wires to doped GaAs-AlGaAs core-multishell nanowire lasers
Semiconductor nanowires (NW) are rapidly emerging as a new generation of miniaturized on-chip coherent light sources by virtue of their unique geometry. In particular, due to the natural Fabry-Perot resonators formed by guided modes between the NW-endfacets, combined with the possibilities for direct monolithic integration on Si, NW lasers offer attractive applications in future optical interconnects and data communication.
Until now these NW lasers are driven optically, an electrical operation of the device is crucial for all applications. For this purpose, electrical contacts and a precise control of the doping profile in the device is required. The aim of this maswters thesis project is to develop appropriate process technologies to contact doped core-multishell NWs in a lying and standing geometry. This enables the characterization of the devices with respect to their electrical properties. Moreover, a comprehensive 2D-3D TCAD model of the NW laser will be implemented to simulate the electrothermal performance of the device. Adjusting the simulations to the measurement results enables the optimization of the doping profile and the heterostructure design of the NW laser. Experience in the area of clean room fabrication or TCAD modeling is a benefit, but secondary to motivation, commitment and a willingness to work as part of a team.
