Popis: X‐ray diffraction was used to measure microtwinning in (111) CdTe epitaxial films grown on (00⋅1) sapphire substrates by metalorganic chemical vapor deposition. The concentration of microtwins is high near the interface but drops off rapidly with distance. For films grown to thicknesses up to ≊10 μm, the microtwin content is constant and relatively low (much less than 1 vol %) away from the interface. For films grown more than ≊10 μm thick there is a substantial increase in the microtwin content. These microtwins are concentrated near the film surface.
