Abstract

Vapor-liquid-solid nanowisker growth was considered using the Monte Carlo simulation. Dependences of catalyst drop composition on temperature, flux intensity and nanowhisker diameter were obtained. Periodical oscillation of drop composition near mean nonequilibrium value of whisker material concentration was observed. The mean value of this concentration was found to be practically independent of flux intensity and defined by growth temperature. Oscillation period rises with flux decreasing and diameter increasing. Oscillation results from layer-by-layer growth at the drop-whisker interface and necessity of supersaturation creation for growth to start.
