초록

The electrical conductivity of polycrystalline $Gd_2O_3$ has been measured over the temperature range of 650 to 100$0^{\circ}C$ under the oxygen pressure range of $10^{-6}$ to 102 torr. The oxygen pressure dependence of electrical conductivity, $\sigma$ PO211/n is characterized by n value of about 5.3. The defect structure and the type of the oxide are controlled by triply ionized metal vacancies and holes.
