“…Thus, the most characteristic crystalline structure of CdTe under conventional conditions is cubic , whereas the most stable lattice for CdS and CdSe is hexagonal wurtzite [6]. As regards CdSe x Te 1Àx ternary alloys of interest, Uthanna and Reddy [7], Mangalhara et al [8] and Islam et al [9] have observed the presence of only cubic phase over the entire composition range. Nevertheless, other studies [10][11][12][13] have revealed that CdSe x Te 1Àx crystallizes in either cubic or hexagonal structure.…”
