Structure and growth mechanism of tetrapod-like ZnO particles

Abstract
Tetrapod-like ZnO particles having four legs shorter than a micrometre have been observed by transmission electron microscopy and electron diffractometry. The particles are composed of six or more wurtzite-type elements. Four of them make legs and others form (1122) twins with the legs. Particles composed of only four wurtzite-type legs are also observed to form three (1124) twins among them. We propose a growth model that the tetrapod-like ZnO particle grows from wurtzite-type multiple twins induced in a zincblende-type nucleus, taking account of the combination of the slips caused at the phase transformation.
