Resumen:
The electrical conductivity of lithium-doped MgO crystals at room temperature is shown to be enhanced by the thermal creation of stable [Li]0 defects by oxidation at elevated temperatures. The current-voltage curves are found to be nonlinear at low voltages. The enhancement in conductivity is attributed to localized regions of high [Li]0 concentration in which the holes at the [Li]0 sites are thermally ionized into the valence band, causing these regions to be semiconducting. © 1980.
