K. Nishio et al., STRUCTURE AND GROWTH-MECHANISM OF TETRAPOD-LIKE ZNO PARTICLES, Philosophical magazine. A. Physics of condensed matter. Structure, defects and mechanical properties, 76(4), 1997, pp. 889-904
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.
