“…On the other hand, ''oxygenated'' cadmium telluride films have been reported by several authors [11][12][13][14][15], as well as surface-oxidized CdTe single crystals [8,[16][17][18][19]. In summary, mainly CdTeO 3 , TeO 2 and CdO are the compounds that have been identified in the above materials as a result of the cadmium telluride-oxygen interaction; however, it seems very plausible that the products are strongly dependant on the preparation and/or surface oxidation technique [9].…”
