Abstract
Several copper-deficient phases in a Cu-In-Se ingot were identified and characterized by electron diffraction and energy dispersive x-ray analysis. Some were phases already identified by x ray and electron diffraction. A new vacancy-ordered phase with composition close to Cu0.75In2.25Se4 was identified to have a thiogallate-type structure. A phase with composition close to CuIn5Se8 exhibited a polytype structure with both 7- and 14-layer stacking sequences.Keywords
