摘要: The local electrical resistivities in deformed n-GaP have been measured by scanning spreading resistance microscopy (SSRM). SSRM images show chainlike alignments of spots with high resistivity along the slip direction. These can be attributed to carrier-depletion around a charged dislocation. From observed spot size, line charge density dislocations has estimated 0.4–0.9e/b, where b denotes magnitude Burgers vector. value discussed relation dislocation core structure.
