Abstract

Dislocations were introduced in wurtzite zinc oxide single crystals by Vickers indentations on {21̄1̄0} and {101̄0} surfaces at elevated temperatures, and their slip systems were determined by transmission electron microscopy combined with etch pit observations. The observed system for {21̄1̄0} indentations was {101̄1̄} 〈1̄21̄0〉 or (0001)〈1̄21̄0〉, while that for {101̄0} indentations was {101̄0}〈1̄21̄0〉. Activation of the slip systems was briefly discussed in terms of the Peierls stress and resolved shear stress acting on the slip systems.
