TL;DR: In this article, the effects of doping of vacuum-evaporated CdS thin films with indium and antimony were studied and the properties specifically studied are (1) the dark conductivity and photoconductivity as functions of temperature and dopant concentration, (2) the Hall mobility and carrier concentration at room temperature, (3) the thermally stimulated current and (4) the spectral response and optical density.

TL;DR: In this article, a detailed study was done to evaluate a•Si:H materials deposited at high substrate temperatures (≥325 °C) and their characteristics and nature of light induced degradation were compared to a• Si:H deposited at 200 Ã −C. The results have been discussed in connection with the role of hydrogen motion in the annealing of lightinduced defects.

TL;DR: In this article, the results of optical absorption, IR absorption, Raman scattering and conductivity measurements for hydrogenated amorphous SiN films (a-Si1−xNx:H) prepared by r.f. magnetron sputtering have been presented.

TL;DR: L'etude TEM revele une augmentation de the phase amorphe pour des expositions laser dans la gamme des puissances ou l'on observe l'attenuation du mode de phonons, avec un renforcement subsequent of the cristallinite pour des puISSances superieures.

TL;DR: In this article, a combination of Raman scattering experiment and infrared (IR) vibrational spectroscopy was performed to study the structural characteristics of the a-Si:H films and it was inferred that growth conditions mainly governed by BH3 radicals led to highly conducting films.
