... in the growth of SiNWs. Because this growth process involves solid–liquid–solid phases, it is named as a SLS growth, which is in fact an analogy of the VLS mechanism. The growth process of the ... species were ablated o by the laser beam, and the growth of the SiNWs is controlled by the well-known VLS mechanism. The central idea of the VLS growth of SiNWs is that, th...
