PROBLEM OF THE ANOMALIES OF THE LOW-TEMPERATURE TRANSPORT COEFFICIENTS OF Hg1 minus xCdxTe.

An investigation was made of the low-temperature anomalies of the electrical resistivity and Hall coefficient of p-type Cd//0//. //2Hg//0//. //8Te crystals which were not subjected to any heat treatment. The presence of anomalies was found to depend largely on the conditions during synthesis of these crystals. A cluster condition mechanism was proposed, according to which the formation of a connected network of paths of flow of the electron current is possible in a p-type material. It was found that the connectivity of one of two interpenetrating clusters may be destroyed in thin samples and this may alter the temperature dependences of the transport coefficients at low temperatures.
