Cadmium diffusion into p-type PbTe wafers and out of n-type Cd-diffused PbTe wafers was studied. The electrical properties and Cd content of the wafers showed that only about 150 ppm of the diffused Cd affect the electrical properties of PbTe. The fact that most of the diffused Cd has no...
Hall‐effect, conductivity, and solubility measurements were carried out on Cd‐diffused PbTe and Pb1−xSnxTe single crystals, doped under various Cd vapor partial pressures between 10−4 and 10−1 Torr. Most of the diffused Cd atoms are found to distribute uniformly as an electrically ina...
