Transport properties of the CdxPb1$minus$x Te alloy system

Abstract

The Hall mobility and thermoelectric power of n- and p-type CdxPb1−x Te alloys with x = 0·03, 0·06 and 0·11 have been measured at temperatures within the range 77 to 450 K for carrier concentrations within the range 1016 to 1020 cm−3. The results have been interpreted using a two valence band model. The energy separation between valence bands was found to decrease with alloying and this had the important consequence that direct information could be obtained concerning heavy-mass hole conduction.
