Picture of the day


VLS Silicon Nanowire

High-crystalline silicon and other semiconducting nanowires are key building blocks for electronic devices, light emitting devices, field emission sources and sensors. Pictured is a crystalline silicon nanowire grown by the vapour-liquid-solid mechanism (VLS). VLS growth is so named because the constituents in gas form precipitate through a liquid catalyst onto a solid crystallin surface. Thermal-vapour-growth from solid precursors, usually in a high temperature furnace, is the most common way to obtain a bulk production of nanowires.
