Abstract

A semiconductor device (101) is provided herein which comprises a substrate (103) comprising germanium. The substrate has source (107) and drain (109) regions defined therein. A barrier layer (111) comprising a first material that has a higher bandgap (Eg) than germanium is disposed at the boundary of at least one of said source and drain regions. At least one of the source and drain regions comprises germanium.
