Habit, structure and surface formation of Te particles deposited in a high-resolution transmission electron microscope

Abstract

Te particles which are vacuum-deposited by electron beam heating in situ in an electron microscope are observed by high-resolution electron microscopy with the aid of image simulation. They grow into slender crystals elongating along the c-axes. A crystal which grows into a hole of the substrate and has three fin processes can be determined to be a left-handed crystal (P3 221) with the [100] direction along the incident beam, from the lattice images in the fins, taking account of its crystal habit. Video recording of the surface profile images of the crystal reveals the formation process of the stable (01 1 ) surface.
