Thermal and Optical Energy Gaps in Pb0.93Sn0.07Te and Pb0.85Sn0.15Te
The optical absorption edge (indirect energy gap) was determined for Pb0.93Sn0.07Te and Pb0.85Sn0.15Te in the temperature range from 80° to 520°K. The variation of Eg with temperature indicated that two valence bands were operative. Below 300°K, linear variation of bandgap with temperature was obser...
