Electrical Conductivity of Single-Crystal Cuprous Oxide at High Temperatures

Abstract
The electrical conductivity of single-crystal Cu2O was measured in the temperature range of 1100° to 500°C in oxygen pressures from 152 mm to 105 mm of Hg. The logσ vs logP(O2) curves were found to be linear between the oxygen pressures of 50 mm and 102 mm, with an average slope of 0.1420, or approximately 17. These curves exhibit a radical change in slope at O2 pressures below 102 mm.
