ABSTRACT:
A semiconductor device and the methods of forming the same are provided. The semiconductor device includes a low energy band-gap layer comprising a semiconductor material; a gate dielectric on the low energy band-gap layer; a gate electrode over the gate dielectric; a first source/drain region adjacent the gate dielectric, wherein the first source/drain region is of a first conductivity type; and a second source/drain region adjacent the gate dielectric. The second source/drain region is of a second conductivity type opposite the first conductivity type. The low energy band-gap layer is located between the first and the second source/drain regions.
