An investigation was made of the thermoelectric effects in narrow-gap bulk p-type Cd/sub x/Hg/sub 1-x/ Te single crystals with 0.1<0.3 in the temperature range 4.2< or =T< or =300/sup 0/K. Anomalies in the temperature dependences of the thermoelectric power were observed: there was a low-temperature inversion of the sign of ..cap alpha.. in the range 4.2<20/sup 0/K or an increase in vertical-bar..cap alpha..vertical-bar in the same temperature range. The observed anomalies were explained using a model of an impurity acceptor band overlapping the conduction band. A criterion was obtained for the determination of the sign of ..cap alpha.. for materials with an impurity acceptor band.
