Atomic‐Scale Mechanisms of Anisotropic Thermal Decomposition in GeSn Alloys With Stepwise Pinning

ABSTRACT Thermal decomposition of GeSn layers detrimentally affects device performance, while the governing mechanisms remain shrouded by the presence of SiO 2 passivation. In this work, we elucidate the atomic‐scale decomposition of GeSn during thermal degradation using in situ...
