Free-running Sn precipitates: an efficient phase separation mechanism for metastable Ge(1−x)Sn(x) epilayers

The revival of interest in Ge(1−x)Sn(x) alloys with x ≥ 10% is mainly owed to the recent demonstration of optical gain in this group-IV heterosystem. Yet, Ge and Sn are immiscible over about 98% of the composition range, which renders epilayers based on this material system inherently metastable. He...
