摘要: A method of fabricating a layer of single crystal semiconductor material on a silicon substrate including providing a crystalline silicon substrate and epitaxially depositing a nano structured interface layer on the substrate. The nano structured interface layer has a thickness up to a critical thickness. The method further includes epitaxially depositing a layer of single crystal semiconductor material in overlying relationship to the nano structured interface layer. Preferably, the method includes the nano structured interface layer being a layer of coherently strained nano dots of selected material. The critical thickness of the nano dots includes a thickness up to a thickness at which the nano dots become incoherent.
