(a) A FM image of a micropattern created at a laser power of ~73 mW. (b) A FM image of the micropattern (a) after 1-hr annealing in vacuum (10−2 Torr) at 300°C. (c) PL spectrac of the laser-treated region before (in red) and after annealing (in blue). (d) PL spectra of the pristine mp-SiNWs before (in red) and after annealing (in blue).
