Defects and high temperature electrical properties of Nd2-xCexCuO4-y
Description
The defect structures and transport properties of Nd2-xCexCuO4-y for x = 0-0.20 are studied by dc electrical conductivity and thermoelectric power measurements for temperatures of 25-1,000C and PO2's of 1-10-4 atm. The conductivity of the undoped sample shows a typical n-type semiconductor behavior as confirmed by PO2 dependence and the sign of the thermoelectric power. Measurements obtained in a fixed-composition cooling experiment indicate that the mobility is not thermally activated. Ce doping progressively increases the absolute conductivity which reaches a maximum at x = 0.15. A defect model is proposed to explain these results
