摘要: A biaxially textured crystalline layer formed on a substrate is provided. The biaxially textured crystalline layer includes an oriented CaF2 crystalline layer having crystalline grains oriented in both in-plane and out-of-plane directions, where the out-of-plane orientation is a (111) out-of-plane orientation. The oriented CaF2 crystalline layer is disposed for growth of a subsequent epitaxial layer and the CaF2 crystalline layer comprises an IBAD CaF2 layer. The biaxially textured CaF2 layer can be used in a photovoltaic cell, an electronic or optoelectronic device, an integrated circuit, an optical sensor, or a magnetic device.
