Abstract
Structures consisting of alternating Te and Zn layers were prepared by RF-sputtering. Grazing incidence X-ray diffraction (GIXD) measurement s revealed the formation of ZnTe and the existence of free Zn in as-de posited samples. Similar measurements on samples annealed for 2 h at 3 00 degrees C showed enhanced crystallinity of ZnTe as well as the form ation of oxides when annealing time is extended to 8 h. UV-Visible-NIR transmission measurements showed that metallic-type absorption domina tes in as-deposited samples. Annealed samples at 300 degrees C showed well defined absorption edges with an energy gap of 2.50 eV for anneal ing times of 2 h and 2.24 eV when the annealing time is extended to 8 h.
