Abstract:
The effect of an excess of oxygen on the electric conductivity of a pre-illuminated and heated single crystal of Cu2O is investigated. It is found that the influence of illumination on the electric conductivity, together with the concentration of impurities, increases with increasing oxygen pressure during annealing.
