RESEARCH IN THERMOELECTRIC MATERIALS,

Abstract

The electronic properties of single crystals of alloys of PbTe and SnTe in various ratios between the two limits are being studied. PbTe and SnTe are isomorphous and form a continuous series of solid solutions. The carrier sign of PbTe can be changed from 'n' type for excess Pb to 'p' type for excess Te. SnTe is 'p' type and extrinsic for all stoichiometric ratios. When more than 15% SnTe is alloyed with PbTe the alloys become 'p' type. The average carrier concentration as determined from Hall effect in general increased with increasing SnTe and was also found to be sensitive to changes in the composition range of stability of the compound (retrograde solubility etc.).
