IR, pbotoconductivity, Raman and photothermal deflection spectroscopy measurements were used to probe the relationship between material quality and the amount of microsl~ucture in glow discharge deposited a-SiC:H and a-SiGe:H films. We find that the microstructure is directly responsible for the dec
