Abstract
ABS>The effect of dislocations on the rate of diffusion of radioactive Ge/sup 71/ in intrinsic germanium single crystals was studied at temperatures near 740 deg C. The dislocations were . introduced by either distorting the surface by lapping under pressure, thus producing a network of dislocations; or bending the specimens so as to introduce up to 2 x 10/sup 6/ parallel edge dislocations per cm/sup 2/. Both deformation treatments produce an enhancement of self-diffusion relative to that in undeformed crystals. In both cases the diffuston can be described in terms of an enhanced volume diffusion with apparent diffusion coefficients up to 38% larger than the value for undeformed intrinsic specimens. (auth)
