Abstract
A high-resolution transmission electron microscopy image of a microcrack in single-crystal silicon induced by Vickers indentation at ambient temperature is presented. Two 60o dislocations can be clearly seen at the crack tip. The surface of the crack shows a step structure. This microplastic crack is compared with an atomically sharp crack.Keywords
