Abstract :
In this work we analyze the growth of CdTe films by close space sublimation as well as the modification of their properties by using low energy ion sputtering. The structure and composition of the films are studied as a function of different growth parameters. The properties of the CdTe films after ion beam irradiation are studied by using AFM and photo-luminescence techniques. Morphological changes have been observed as a result of the sputtering process; in particular, an increased roughness average has been noticed after irradiation.
