Thin films

Typical X-ray diffractogram of CdS thin films as grown. Inset shows XRD pattern of the CdS thin films reported in [9].. SEM images of CdS thin films prepared in the bath with 3 ml of 1M CdSO 4 solution for 9h (a) and with 25 ml of 1M CdSO 4 solution for 2h (b).. The typical Raman spectrum of the as-prepared CdS thin films is displayed in Fig. The related researches [6] show that Raman spectra of CdS thin films strongly depends on the film grain size and thickness.

Investigation of zinc oxide thin film by spectroscopic ellipsometry

An accurate determination of the optical constants of these films is extremely important prior to its application in optical devices and spectroscopic ellipsometry provides a reasonably accurate method for the determination of optical constants of thin films. In this study, we present the results gained by analyzing spectroscopic ellipsometry of ZnO thin film combined with comparison of transmission spectroscopy measured on a UV-VIS-NIR spectrophotometer.
