Abstract
The effects of surface orientation on growth from the vapor phase and properties of Cu(ln,Ga)Se2 on GaAs (001), (111)B, (111)A, and (110) are discussed. Faceting was observed on CIGS on GaAs (110), resulting in two polar {112} facet types with strikingly different surface morphologies. The {112}Se surface is assigned as the growth front, while growth on {112}Metal planes is relatively slow. A study of CIGS on GaAs (111)A and (111)8 substrates was carried out and we present a growth model based on the results. The possible surface reconstructions, chemical compositions and the electronic structures of the two {112} surfaces have been investigated and are discussed in the context of CdS/CIGS interfaces and device performances.
