Abstract:
The contrast of extended defects representing dislocations and grain boundaries has been calculated for the X-ray-beam-induced current (XBIC) method. It is established that the maximum contrast increases with the diffusion length of excess charge and decreases with increasing X-ray beam width. The simulated XBIC profile contrasts are compared to experimentally measured patterns.
