Modulation Spectroscopy of Disordered Solids.
Abstract
Modulation spectroscopy has been used to study disordered solids with a view toward using modulation spectroscopy to detect band edges in amorphous semiconductors. The Ge-Te binary alloy system was chosen for the study; samples spanned five different composition. Thermoreflectance spectra were obtained which range from being rather featureless for the Ge-rich compositions to showing prominent structure (two negative peaks) for the Te-rich compositions. The peaks were correlated to the bonding and non-bonding electron states associated with the Te atoms. Work was done toward expressing the thermoreflectance in terms of the electronic structure. Attention was also given to the problem of interpreting the interference dominated spectra below the absorption edge.
