Abstract

Slip patterns around <110> Knoop indentations on <001> GaAs were investigated by cross-sectioning, etching and TEM. The roles of As(g) and Ga(g) perfect and partial dislocations in different parts of the “plastic zone” were investigated. A dislocation free zone was found under indentations.
