Imperfections Associated with Dielectric Breakdown in LiF

摘要

Linear imperfections, oriented in or near the 〈110〉 directions, accompany 〈xxy〉 and 〈110〉 electrical breakdown paths formed in LiF single crystals at room temperature. They may be screw dislocation pairs produced by the action of the electrical field on dislocation loops that were generated in the vicinity of the breakdown path.
