We investigate the thermal stability of germanium-tin (Ge1−xSnx) fins under rapid thermal annealing in N2 ambient. The Ge1−xSnx fins were formed on a GeSn-on-insulator substrate and were found to be less thermally stable than blanket Ge1−xSnx films. The morphology change and material quality of the...
