The line tension and equilibrium configuration of a planer-dislocation shear loop on the basal, prismatic, and pyramidal planes in zinc oxide under an external stress were calculated. An extended version of the formulation of deWit and Koehler applicable to piezoelectric crystals was used, and the piezoelectric effects on the line tension and configuration were estimated. The results for zinc oxide were compared with those for zinc, and the characteristic features of zinc oxide were described.
