One aspect of this disclosure relates to a method for forming a strained silicon over silicon germanium (Si/SiGe) structure. In various embodiments, germanium ions are implanted into a silicon substrate with a desired dose and energy to be located beneath a surface silicon layer in the substrate. The implantation of germanium ions at least partially amorphizes the surface silicon layer. The substrate is heat treated to regrow a crystalline silicon layer over a resulting silicon germanium layer using a solid phase epitaxial (SPE) process. The crystalline silicon layer is strained by a lattice mismatch between the silicon germanium layer and the crystalline silicon layer. Other aspects are provided herein.
