Thermopower in n-Cd0.2Hg0.8Te (6–100 K) is studied. A large effect of drag of the charge carriers by phonons αph is found. The influence of the magnetic field H on the drag thermopower is considered. It is established that the magnetic field exert

Conductivity σ(T) and Hall constant R(B, T) are studied for Ag2Te with excess 0.1% of Te. The change in the R sign from (−) to (+) is found in dependences R(B) at various temperatures. In the temperature dependences of R in a range of 1–3 kG, tw

It is established that nonuniformity of electrical parameters conditioned by a nonuniform distribution of excess Te exists along the single-crystal PbTe ingot. In addition to the shallow acceptor and donor levels, deep acceptor levels with activation
