Quantum Solid State Physics Research Group
studies quantum correlated phenomena in semiconductor nanostructures.
Our topics include spin and charge dynamics in quantum dots formed in GaAs, Si or carbon based materials,
electric properties of two-dimensional systems in GaAs/AlGaAs or Si/SiO2 heterostructures and
the characterization of semiconductor surfaces using low-temperature scanning probe microscopies.
Facilities we use include molecular beam epitaxy, electron beam lithography,
low-temperature scanning tunnel microscopy with MBE chamber systems and several cryostats.
