Preparation and Morphology of Boron Filamentary Crystals Grown by the Vapor-Liquid-Solid Mechanism

Abstract

α-rhombohedral boron has been grown by the vapor-liquid-solid mechanism using the reduction of BCl3 with hydrogen for transport and platinum as the liquid-forming agent. Both straight and kinked whisker crystals were produced with 〈4̄401〉 growth directions.
