The Spin Density and Optical Properties of Amorphous Thin Arsenic Silicate Films

Abstract: The spin density of amorphous As,O,/SiO thin films is found to be lower than that of SiO films deposited under similar conditions. The measurements show a decrease in the spin density of an amorphous As,O,/SiO film with increasing temperature which can be explained in terms of some annealing of dangling bonds. The fundamental absorption edge of these films a t different temperatures is investigated and analysed assuming optical absorption by indirect transitions. The infrared absorption spectra indicate some c… Show more
