Microhardness in PbTe and related alloys
Abstract
The microhardness of PbTe has been determined as a function of applied load. Work hardening is found to occur with the hardness increasing as the square root of the applied load. The effect of holes for p greater than 10 to the 18th per cu cm is to increase the hardness but no similar effect is found for free electrons. A possible explanation is offered in terms of electrostatic interaction between dislocations and charged impurities. For constant hole concentrations, alloying with SnTe softens PbTe and alloying with CdTe hardens PbTe.
