High-resolution electron microscopy of microsyntactic intergrowth in V nO 2 n-1
Abstract
Structural features of the Magnéli phases V nO 2 n-1 were studied by means of high-resolution transmission electron microscopy. Microsyntactic intergrowth on a unit cell scale of several phases with neighboring n were frequently observed in arc-melted specimens, and this was ascribed to the structural compensation of the local composition fluctuation. Also observed were periodic microsyntaxy, where two neighboring phases intergrow periodically, and the crystallographic shear ( CS) structure with laterally displaced CS planes. The origin of this microsyntactic intergrowth is discussed from the standpoint of the CS plane interaction.
