Ge-GeSn core-shell single nanowire infrared photodetector with superior characteristics for on-chip optical communication
Sudarshan Singh, Subhrajit Mukherjee, Samik Mukherjee +5
Recent development on GeSn nanowires with high Sn content, beyond its solid solubility limit, make them attractive for all group-IV Si-integrated infrared photonics at…
Combined Iodine- and Sulfur-based Treatments for an Effective Passivation of GeSn Surface
Léonor Groell, Anis Attiaoui, Simone Assali +1
GeSn alloys are metastable semiconductors that have been proposed as building blocks for silicon-integrated short-wave and mid-wave infrared photonic and sensing platforms. Exploit…
Dislocation pipe diffusion and solute segregation during the growth of metastable GeSn
Jérôme Nicolas, Simone Assali, Samik Mukherjee +2
Controlling the growth kinetics from the vapor phase has been a powerful paradigm enabling a variety of metastable epitaxial semiconductors such as Sn-containing group IV semicondu…
Kinetic Control of Morphology and Composition in Ge/GeSn Core/Shell Nanowires
Simone Assali, Roberto Bergamaschini, Emilio Scalise +8
The growth of Sn-rich group-IV semiconductors at the nanoscale provides new paths for understanding the fundamental properties of metastable GeSn alloys. Here, we demonstrate the e…
Decoupling the effects of composition and strain on the vibrational modes of GeSn
Étienne Bouthillier, Simone Assali, Jérôme Nicolas +1
We report on the behavior of Ge-Ge, Ge-Sn, Sn-Sn like and disorder-activated vibrational modes in GeSn semiconductors investigated using Raman scattering spectroscopy. By using an…
