Abstract: Cadmium and selenium bilayer have successfully been made by a vacuum evaporation technique on cleaned glass substrates under the vacuum of the order of 10-5mbar. The samples of different thicknesses were prepared by varying Cd:Se ratio as 1:1, 1:1.5,1:2. Rapid thermal annealing (RTA) of some bilayers have been carried out at different temperatures in nitrogen ambient. XRD measurements were made for structural analysis on these as-deposited and annealed samples. RTA studies could show the formation of cadmium selenide at the interface after annealing. XRF measurements were carried out for elemental analysis of these bilayers. XRF studies reveal that the films are found to be cadmium rich at room temperature. The results of CdSe formed from Cd/Se bilayer by RTA are compared with annealed sample.
