Abstract
Plastic deformation of AgBr at and below room temperature produces a conductivity increase that varies linearly with strain. The conductivity increase has a low activation energy, exhibits dispersion at low frequencies, and recovers slowly at room temperature. A small anisotropy in the conductivity increase can be produced which indicates that the increase is greater parallel to the slip planes than perpendicular to them. The conductivity increase is attributed to regions of disorder that are introduced by the deformation, and these regions of disorder appear to be piled-up groups of dislocations in the slip planes of the work-hardened crystal.
