摘要：

Results are reported of combined optical and photoacoustic spectroscopy measurements and electron spin resonance measurements (ESR) in binary alloys:a-SixGe1-x:H at different x values and a-CSi:H at different deposition temperatures. Experimental values of optical data and Urbach tails agree very well with a model which takes into account the band gap fluctuations. The densities of spins as obtained by ESR measurements are correlated with the values of integrated absorption in the low energy range. © 1990.
