Vacancy Dipole Currents of Thermostimulated Depolarization in a Plastically Deformed KCl Crystal

A thermostimulated depolarization current of divacancies ( υ c − υ a + ) created due to plastic deformation of a KCl crystal is detected. The thermostimulated depolarization current with a maximum at 205 K is correlated with the increasing degree of relative deformation of the KCl crystal. The mecha...

Description
Summary:A thermostimulated depolarization current of divacancies ( υ c − υ a + ) created due to plastic deformation of a KCl crystal is detected. The thermostimulated depolarization current with a maximum at 205 K is correlated with the increasing degree of relative deformation of the KCl crystal. The mechanism of effective formation of (Cl 3 − ) aca centers is interpreted as a result of interaction of two mobile interstitial halogen atoms in the field of divacancies ( υ c − υ a + ).
