Abstract
The formation energy g+ of an individual cation vacancy in LiF and NaCl has been measured by means of the temperature dependence of the electrical signals produced by push‐pull deformation of bent crystals and application of the theory of charged dislocations. For LiF: g+=0.74±0.04 eV at 680°K. For NaCl: g+=0.75±0.04 eV at 627°K and 0.72±0.04 eV at 761°K. A comparison with other published results for NaCl reveals some unexplained disagreement.Keywords
