Microstructural transition and degraded opto-electronic properties in amorphous SiGe:H alloys

Abstract
The microstructure of amorphous Si1−xGex:H films with xx=0.2. A corresponding sharp change in the anisotropic character of the SAXS is consistent with a transition to a columnar‐like microstructure above x=0.2. The correlated results provide strong evidence for a direct link between degraded opto‐electronic properties and the increased heterogeneity associated with the microstructural transition.
