(Color online) Evolution of the nanoparticle size distribution over time. Size distributions are presented at the beginning of the pulse (0.1 ns), during melting (8 ns), at the end of the pulse (30 ns), during freezing (57 ns), and after cooling (100 ns). The cutoff in size at 1.7 Å radius is single atoms.
(Color online) Comparison of the multiple-reflections upper bound on the laser absorption and single-pass lower bound. Temperature profiles (a) and average radii (b) over time for both simulations. Size distributions of the initial state, at the end of the laser pulse, and after cooling for 70 ns for multiple absorptions (c) and single-pass (d) case.
(Color online) Distributions before and after PLM, starting from the as-implanted and 6-s RTA final distributions. The distributions after PLM overlay each other.
(Color online) Final particle size distributions during a repeated RTA (a) and PLM (b) cycle. Results from all but the first RTA step overlay each other.
(Color online) Comparison of lower laser powers. Pulse time is constant and total laser fluence is decreased from 0.2 J/cm2 (black, c) to 0.15 J/cm2 (dark gray/red, d) to 0.1 J/cm2 (light gray/green, e). Temperature profiles (a) and average radii (b) are shown for each fluence.
Size-focusing using fine-tuned PLM and RTA; final distribution (solid line) has a FWHM just 14.9% of the average radius.
(Color online) Selected simulations at a interface energy 0.5 J/m2. PLM at a laser fluence of 0.3 J/cm2 (black, c) and 0.15 J/cm2 (dark gray/red, d) are shown. Temperature profiles (a) and average radii (b) are shown for each fluence. Compare Figs. 2 and 5 .
