Abstract
Tetrapod-like ZnO particles having four legs shorter than a micrometre have been observed by transmission electron microscopy and electron d iffractometry. The particles are composed of six or more wurtzite-type elements. Four of them make legs and others form (11 (2) over bar 2) twins with the legs. Particles composed of only four wurtzite-type leg s are also observed to form three (11 (2) over bar 4) 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 t ransformation.
