To keep up with the demand for faster and, becoming increasingly more relevant nowadays, energy-efficient electronics, smart solutions targeting power consumption are required. Integration of photonic components, e.g. for replacing part of copper interconnects, could strongly reduce on-chip dissipation. Prerequisite for efficient active optoelectronic devices, however not available in group IV elements, is a direct bandgap. Only recently though, a truly silicon-compatible solution was demonstrated by tin-based group IV GeSn alloys, which offer a direct bandgap for a cubic lattice and Sn concentrations above 9 at. %F PUB:(DE-HGF)11 ; PUB:(DE-HGF)3 %9 Dissertation / PhD ThesisBook %R 10.18154/RWTH-2018-221225 %U https://publications.rwth-aachen.de/record/717204
