Abstract
Mott type variable range hopping conduction has been observed in a wide tem perature range (1.6 to 100 K) in several barely insulating single-crystalli ne samples of p-type compensated CuInTe2. In the less doped sample, a cross over to Efros-Shklovskii type variable range hopping conduction is found by lowering the temperature below 18 K, an unusually high temperature for thi s type of phenomenon. The crossover temperature T-c then deduced is not so far from that one I,an calculate.
