摘要：
The electrical conductivity, thermoelectric power and dielectric constant of ErKMo2O8 single crystal in the temperature range 300-1000 K have been studied. ErKMo2O8 is a p-type semiconductor with energy band gap 2.6 eV. It exhibits an extrinsic nature up to 625 K and above 625 K it exhibits an intrinsic nature. The thermoelectric power increases with temperature in the region 300-625 K whereas it decreases with temperature in the region 625-1000 K. The dielectric constant increases slowly in the temperature ranges 300-600 K and 750-1000 K while its increase becomes fast in the temperature range 600-750 K.
