caption_attribution_description: English: Figure 1: Schematic illustration of Si whisker growth from the reaction of SiCl4 and H2 vapor phases. This reaction is catalyzed by gold-silicon droplet deposited on the wafer surface prior to whisker growth. Русский: Рисунок 1: Схема роста кремниевых нановискеров в результате газофазной реакции SiCl4 и H2. Реакция катализируется каплями расплава золото-кремний, под которыми происходит рост вискера.
context_page_description: The vapor–liquid–solid method is a mechanism for the growth of one-dimensional structures, such as nanowires, from chemical vapor deposition. The growth of a crystal through direct adsorption of a gas phase on to a solid surface is generally very slow. The VLS mechanism circumvents this by introducing a catalytic liquid alloy phase which can rapidly adsorb a vapor to supersaturation levels, and from which crystal growth can subsequently occur from nucleated seeds at the liquid–solid interface. The physical characteristics of nanowires grown in this manner depend, in a controllable way, upon the size and physical properties of the liquid alloy.
