Growth of b-axis oriented VO2 thin films on glass substrates using ZnO buffer layer

Vanadium oxide thin films have been deposited on glass and ZnO-coated glass substrates by reactive RF-magnetron sputtering deposition at different substrate temperature. The introduction of ZnO buffer layer could increase the transmittance. The buffer layer ZnO could lead to the increase of the crystallinity quality of VO2 films and substrate temperature could be decreased to 100°C for the obtaining of polycrystalline VO2 structure. The structure of VO2/ZnO/glass is considered to be potentially applicable to smart windows of high total energy efficiency in architectures or automobiles.

Znte Thin Films

To overcome the naturally existing Schottky barrier problem between p-CdTe and any metal, an intermediate semiconductor thin buffer layer is a better choice prior to the final metallization for contact. Among many investigated back contact materials the ZnTe is suitable as a buffer layer. ZnTe thin films were deposited onto glass substrates by the thermal evaporation technique under vacuum ~2×10-5mbar. Undoped ZnTe thin films are highly resistive, extrinsic doping of Cu was made to improve the electrical conductivity. Films were doped by immersing in Cu NO32.5H2O solutions for Cu doping. To optimize the growth parameters the prepared films were characterized using various techniques. The structural analysis of these films was performed by X-ray diffraction (XRD) technique and optical transmission. X-ray diffraction identified the phases present in these films and also observed that the prepared films were polycrystalline. Also the spectral dependence of absorption coefficient was determined from spectrophotometer. Energy band gap index were calculated from obtained optical measurements data.
