Abstract
The electrical conductivity, thermoelectric power and dielectric constant of Eu2Ti2O7 single crystal have been studied in the temperature range 300–1000 K. Eu2Ti2O7 is found to be a n-type semiconductor with energy band gap of 2.5 eV. The compound exhibits an extrinsic nature upto 700 K and intrinsic nature above 700 K. Thermoelectric power decreases with temperature in the region 300–700 K whereas it increases with temperature in the region 700–1000 K. Dielectric constant increases with temperature in the entire temperature range studied with a discontinuity atT ∼ 700 K.
