CROSS-SECTIONAL TRANSMISSION ELECTRON-MICROSCOPY OF ZNO TETRAPOD-LIKEPARTICLES

ZnO tetrapod-like particles having legs as long as several tens of mic rometers have been observed by cross-sectional electron microscopy, Th e specimen is prepared by a new method where a photo-resist suspension of the particles fills up holes of an electron microscopy grid and is solidified for the subsequent ion-milling, Electron diffraction and h igh-resolution electron microscopy of a section of a ZnO tetrapod reve al the orientation relationship among its four legs, which enables us to discuss on the growth mechanism of these particles.
