25% Zinc doped Cadmium Telluride thin films were prepared using Stacked Elemental Layer method. The structural studies were conducted by the X-Ray technique and the results were compared with standard data which confirmed the presence of mixed phases (CdTe, ZnTe and CdZnTe) in the stack annealed at 425°C. Transmittance spectra depicted the effect of Zn on the optical properties of CdTe thin film. The calculated band gaps from the transmittance spectra were lie between 1.42 and 1.51eV. Scanning Electron Microscope images elucidated the influence of Zn on surface morphology and the grain growth for CdTe thin films.

VO2 thin films with thickness from 100 nm down to 2 nm were prepare on C-plane sapphire (0001) substrates by magnetron sputtering and remarkable thickness-dependent structural and optical properties were found. Below 10 nm the films are nonconductive, and their phase transition temperatures are reduced to be much lower than those of the continuous, thick films. Structural defects are believed to be the main reason for this temperature reduction.
