Abstract
The issue of the minimum diameter of nanodimensional whiskers (NWs) which can be achieved under given deposition conditions is considered within the framework of a kinetic model describing the NW growth according to the vapor-liquid-solid (VLS) mechanism. Based on the results of numerical modeling, it is shown that the minimum NW diameter can be determined not only by the Gibbs-Thomson dimensional effect, but also by the kinetic factors controlling growth on the substrate surface. The results of numerical calculations of the growth rate of NWs with various diameters are presented.
