Electrical Conductivity of Single-Crystal Cuprous Oxide at High Temperatures

Authors:

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 10−5 mm of Hg. The logσ vs logP(O2) curves were found to be linear between the oxygen pressures of 50 mm and 10−2 mm, with an average slope of 0.1420, or approximately 17. These curves exhibit a radical change in slope at O2 pressures below 10−2 mm.
