Abstract

Using transmission electron microscopy, we have found stacking faults on the cation sublattice in the chalcopyrite structure of CuInSe2. These films are grown by molecular beam epitaxy under Cu-rich conditions. These stacking faults are found to extend large distances in the plane of the film, and are not found to be present in samples not grown in Cu-rich conditions. We suggest that this defect is triggered by a Cu-induced transformation of the surface structure of the growing film.

13. We index throughout the paper with respect to the CuInSe2 chalcopyrite structure, assuming c-axis is perpendicular to the film, and the symmetric a and b axes in the plane of the film, unless stated otherwise. Thus, the close-packed {112} planes correspond to the {111} planes of GaAs.Google Scholar

15. The [120] and [210] axes are interchangable but not equivalent. They differ only by a [0,1/2,1/4] translation vector; you can thus observe that one is different from the other, but it is arbitrary which one is [120] and which is [210].Google Scholar
