Abstract: The present invention provides a semiconductor material that has enhanced electron and hole mobilities that comprises a Si-containing layer having a crystal orientation and a biaxial compressive strain. The term “biaxial compressive stress” is used herein to describe the net stress caused by longitudinal compressive stress and lateral stress that is induced upon the Si-containing layer during the manufacturing of the semiconductor material. Other aspect of the present invention relates to a method of forming the semiconductor material of the present invention. The method of the present invention includes the steps of providing a silicon-containing layer; and creating a biaxial strain in the silicon-containing layer.
