The authors have examined the effects of scandium replacing germanium on the structure, electrophysical parameters, and phase transitions in solid solutions based on germanium telluride in the GeTe-ScTe and GeTe-ScTe-PbTe systems. X-ray and dilatometric measurements on solid solutions based on GeTe in the GeTe-ScTe and GeTe-ScTe-PbTe systems show that ScTe dissolving in GeTe substantially reduces the rhombohedral distortion in the ..cap alpha.. phase and reduces the ..cap alpha.. ..-->.. ..beta.. transition temperature. Scandium monotelluride has a donor action in germanium telluride and reduces the hole concentration but increases the thermo-emf.
