Abstract
An interpretation is given of the anisotropic effects observed by Arthur et al. (1958) in germanium containing parallel arrays of edge dislocations. The anisotropy of the diffusion constant and high field mobility in N-type crystals is considered quantitatively. The diameter of the space-charge cylinder surrounding the dislocations (1.6 × 10−4 cm) and the fraction of time an injected hole spends within the space-charge region (1/2) is deduced from the analysis.
