Abstract

The effects of crystal tilt on HREM images of crystals with hexagonal structure by crystal model construction and high resolution image simulation performed in the CERIUS 3.1 program. Some simulated images of 6H-SiC crystals with different tilting angles and tilting azimuths were shown. All images showed characteristics of alternate bright/dark contrast except for those tilted toward [0001] direction. The crystal model showed that the relative positions of carbon atoms with respect to the closest Si atom switch for every three (0006) planes, and that other hexagonal compounds show properties similar to 6H-SiC.
