Mechanism of surface conduction in alkali halides
Both surface and bulk conductivity measurement have been simultaneously performed in NaCl single crystals cantaining Ca 2− of 10 ppm purity in the temperature range of 200–650 °C. The experimental results have been analyzed in terms of a double layer near the crystal surface. The formation energy of...

Summary: | Both surface and bulk conductivity measurement have been simultaneously performed in NaCl single crystals cantaining Ca
2− of 10 ppm purity in the temperature range of 200–650 °C. The experimental results have been analyzed in terms of a double layer near the crystal surface. The formation energy of positive ion vacancy at the surface is found to be 0.57 eV. |
