Offered Bachelor’s or Master’s Theses Topics

Optoelectronics of tunnelling devices based on single atomic defects
Structuring materials with atomic precision is the ultimate goal of nanotechnology and is becoming increasingly relevant as an enabling technology for quantum electronics and photonics. The goal of this thesis is to create optically active atomic defects in semiconducting two-dimensional materials, such as MoS2, by helium ion beam lithography with a spatial fidelity approaching the single-atom limit in all three dimensions and to characterize corresponding tunnelling and gate-switching devices. As was demonstrated very recently, such defects can act as single photon emitters with potential applications in quantum communication and sensing. Different layered materials will be combined into few-nm thin heterostructures and they will be integrated into electronic field effect structures to switch the atomic defect states on and off. The material properties will be characterized by different spectroscopies (such as Raman spectroscopy, electron beam and atomic force microscopy). Interest and good knowledge in solid state physics, semiconductor physics, Python programming, optoelectronics or nanofabrication is a plus, but certainly not a must.

Symmetries of 2D materials and their heterostacks
Atomically thin van der Waals crystals form truly two-dimensional materials with remarkable quantum effects. Examples range from semi-metallic graphene to topological insulators and semiconducting materials with a thickness of only few atoms. The goal of this project is to characterize the fundamental symmetries of the underlying crystals and optical properties of such two-dimensional materials determined by optical means including Raman, photoluminescence (PL) and second harmonic generation (SHG) measurements, and to understand their optical properties particularly in two-dimensional heterostacks. The latter allow to build atomically thin field-effect, tunnelling, and photovoltaic devices. Interest and good knowledge in solid state physics, semiconductor physics, Python programming, optoelectronics or nanofabrication is a plus, but certainly not a must.
