Design of a waveguide-coupled GeSn disk laser
Bahareh Marzban, Jovana Nojic, Daniela Stange +2
We report on the design of a waveguide coupled GeSn microdisk-laser cavity in which the germanium virtual substrate serving as a template for GeSn growth is repurposed for the defi…
Ultra-low threshold cw and pulsed lasing in tensile strained GeSn alloys
A. Elbaz, D. Buca, N. Von den Driesch +15
GeSn alloys are the most promising semiconductors for light emitters entirely based on group IV elements. Alloys containing more than 8 at.% Sn have fundamental direct band-gaps, s…
Thermally activated diffusion and lattice relaxation in (Si)GeSn materials
Nils von den Driesch, Stephan Wirths, Rene Troitsch +5
Germanium-Tin (GeSn) alloys have emerged as a promising material for future optoelectronics, energy harvesting and nanoelectronics owing to their direct bandgap and compatibility w…
Integrated impedance bridge for absolute capacitance measurements at cryogenic temperatures and finite magnetic fields
G. J. Verbiest, H. Janssen, D. Xu +10
We developed an impedance bridge that operates at cryogenic temperatures (down to 60 mK) and in perpendicular magnetic fields up to at least 12 T. This is achieved by mounting a Ga…
