[(a) and (b)] ZnSe nanowires with small diameters show fast growth rates. (c) High-density stacking faults and twins (marked by the arrows) frequently occur in ZnSe nanowires grown at a low temperature. [(d) and (e)] Ultrathin ZnSe nanowires always form hcp structure.
(a) The solid dots indicate the growth rates measured from different diameters of ZnSe nanowires. The dashed line is the fitting curve by and the solid line by . (b) Experimental data of the whisker growth rates reported by Givargizov (see Ref. 2).
Different diffusion models for the source atoms to incorporate into the growth front of the nanowire. (a) The classical VLS. (b) The metal droplet is in partially molten state. Its surface and interface are liquid, while the core of the droplet may be solid. (c) The metal catalyst is solid, but the interface is liquid.
(a) The schematic concentration profile of the source atoms at the catalytic interface. (b) The flux of the source atoms flowing into the catalytic interface.
