Abstract:
1. A semiconductor structure comprising: a SiGe-on-insulator substrate comprising a tensile-strained SiGe alloy layer having a thickness from about 5 to about 300 nm and including from about 1.0 to about 99 atomic percent % Ge located atop an oxide layer having a thickness 1 to about 100 nm and a substrate located below and abutting the oxide layer; a strained Si layer atop the tensile-strained SiGe alloy layer, wherein at least one semiconductor material selected from Si, SiGe, Ge, GaAs, InAs, and InP located between the tensile-strained SiGe alloy layer and the insulating layer; and at least one field effect transistor located on said stained Si layer.
