Abstract
Continuous biaxially textured CdTe films were grown on biaxial CaF 2 buffer layers. The CaF 2 nanorods were grown by oblique angle vapor deposition and possessed a {111} biaxial texture. The CdTe film was deposited by metal organic chemical vapor deposition (MOCVD). Film morphology and the CdTe/ CaF 2 interface were studied by scanning electron microscopy and transmission electron microscopy. Characterization showed that small CdTe grains formed initially from the CaF 2 surfaces. These small grains then merged into large columnar grains during growth. Analysis revealed that the crystalline orientation of the CdTe film followed the biaxial texture of the CaF 2 nanorods.
