Semiconductor epitaxy and quantum optics - AG Pawlis
About
Our group conducts research on the development of novel quantum devices of II/VI and III/V semiconductor nanostructures such as single photon sources, spin qubits and nanowires. We take a holistic approach starting with molecular beam epitaxy of heterostructures, top-down and bottom-up nano-processing of the devices, and electrical and quantum optical characterization of the prototypes - all on-site and from a single source.
Research Topics
- Growth, characterization and development of II-VI and III-V compound semiconductors.
- In-situ fabrication of complex devices using shadow masks
- Processing of quantum devices such as single photon sources, spin qubits and nanowires
- Quantum optical characterization
