Abstract
Two opposite trends in the variation of d spacing (2θ) with composition are observed for the (112) peak position in x‐ray diffraction patterns for evaporated CuGaSe2 films on different substrates. The 2θ value tends to increase with increasing molecularity for Al2 O3 and 7059 glass substrates and decreases for Mo‐coated Al2 O3 and 7059 glass substrates. The films are composed of CuGaSe2 plus impurity phases, and the ‘‘actual’’ molecularity of the CuGaSe2 does not exceed 0.5.Keywords
