Efficient In Situ Doping of Strained Germanium Tin Epilayers at Unusually Low Temperature

Advanced Electronic Materials, Volume 10, Issue 9, September 2024.
Efficient p‐ and n‐type in situ doping of compressively strained germanium tin (Ge1‐xSnx) semiconductor epilayers, grown by chemical vapor deposition on a standard Si(001) substrate, is demonstrated. Materials characterization results reveal unusual impact of dopants manifesting via a pronounced reduction of Sn content in the epilayer, accompanied by ...
