Role of dislocations in scattering of charge carriers in mechanical polishing damaged layers of silicon wafers

Physical processes resulting in the anomalous (cubic) dependence of the small-angle IR scattering intensity from near-surface layers of mechanically polished silicon and germanium wafers on the photoexcitation power were revealed. It was shown that extended linear defects and dislocations in the damaged region contribute predominantly to carrier scattering.
