Propagation of amorphous oxide nanowires via the VLS mechanism: growth kinetics.

ABSTRACT: This work reports the growth kinetics of amorphous nanowires (NWs) developed by the vapour-liquid-solid (VLS) mechanism. The model presented here incorporates all atomistic processes contributing to the growth of amorphous oxide NWs having diameters in the 5-100 nm range. The steady state growth condition has been described by balancing the key atomistic process steps. It is found that the 2D nano-catalyst liquid and NW solid (L-S) interface plays a central role in the kinetic analysis. The balance between the 2D Si layer crystallization and oxidation rate is quantitatively examined and compared with experimental values. The atomistic process dependencies of the NW growth rate, supersaturation (C/C ⁰), desolvation energy (Q _D) barrier and NW diame
