About Some Fundamental Aspects of the Growth Mechanism Vapor-Liquid-Solid Nanowires

This study provides the formation of semiconductor nanowires (NWs) with a singular facet and curved end surface by vapor-liquid-solid (VLS) process that is analyzed explained in details. Given evidence, it confirmed wettability liquid catalyst droplet on crystal contact angle between play an essential role VLS NWs development. It shown for mechanism, depends reduction activation barrier to crystallization caused release surplus-free energy spheroidizing drop region triple junction during lowering area. decreases necessary supersaturation development NW vertex facets at fixed growth rate. The source extra free drives movement steady-state droplet’s outer surface. During NWs, those angles inclination lateral are obtained which solid/vapor, solid/liquid, liquid/vapor interfaces experience smallest increase energy. wetting hysteresis demonstrated occur may be regarded as independent fully-fledged thermodynamic parameter system’s state.
