Abstract
Optical absorption measurements are reported for rf sputtered a-P films prepared under conditions of variable substrate temperature. Variations in the optical gap with Ts are similar to changes in the Raman scattering and x-ray diffraction spectra. The results suggest that intermediate-range order plays an important role for the structural, vibrational and optical properties for more ordered a-P films. Photostructural effects in As-chalcogenides which exhibit analogous behavior also suggest modifications of intermediate-range order.
