Photo Induced Studies on Chalcogenide Thin Films: Photo and Thermal Induced Studies on Sb/as2s3 Multilayered and (As2s3)1-xsbx Thin Films Ramakanta Naik

The main aim of this book is to study the photoinduced diffusion in Sb/As2S3 nanolayered films and (As2S3)1-xSbx bulk thin films. In literature, there are reports about the photoinduced interdiffusion in Se/As2S3 and Bi/As2S3 nanolayered films, but the mechanisms of photoinduced interdiffusion of these elements are not very clear. Raman scattering and infrared spectroscopy techniques have been used to study the photoinduced interdiffusion in Se/As2S3 and Bi/As2S3 nanolayered films. But many questions remain unanswered. The characteristic spectra of components in the multilayer and those of the diffused layer were rather similar. In the present book, photoinduced interdiffusion in Sb/As2S3 nanolayered samples are studied by Fourier Transform Infrared spectroscopy (FTIR) at room and low temperature and X-ray photoelectron spectroscopy (XPS). The photoinduced effects in (As2S3)1-xSbx thin films are studied by FTIR, XPS and Raman Spectroscopy. The book consists of seven chapters. References are given at the end of each chapter.
