[交流] 对VLS机理的理解有帮助

http://springer.lib.tsinghua.edu ... 150605/fulltext.pdf
Growth parameters and shape specific synthesis of silicon
nanowires by the VLS method
When
the gold nanoparticles are present on the growth
substrate, the VLS process proceeds in three main
steps. Firstly, the alloying process consists of the
formation of liquid droplet containing the metal
catalyst and dissolved Si. For gold, the eutectic
composition is obtained at 363 C. Secondly, when
the silicon concentration reaches the upper solubility
limit, nanowire nucleation commences. At this stage,
a three phase biphasic system (SiH4 gas, Au/Si alloy...............
