Crystallographic Features of ZnO Single Crystals

Abstract

The atomic arrangements of ZnO single crystals have been investigated in detail using ion channeling methods. The ZnO crystals were grown by a flux method, and we focused on the channeling properties along the axis. In particular, to obtain information on O atoms in the crystal, a nuclear reaction induced by D⁺ ions was observed. As a result, it was revealed that the atomic arrangement of O atoms along the direction is better than that of Zn atoms in contrast with simple anticipation. This is quite remarkable but is regarded as one of the structural features of the crystal.
