Figure 1From: Silicon nanowires prepared by electron beam evaporation in ultrahigh vacuumSEM images of 1D Si nanowires, 2D Si growth and AFM images of AuNPs. (a) SEM image of 1D Si nanowires grown through VLS on Si substrate, (b) SEM image of 2D Si growth without Au nano-catalysts on Si substrate, and (c) AFM images of AuNPs prepared by similar depositions on SiO2 substrate.Back to article page
