Selective Pulsed Heating for the Synthesis of Semiconductor and Metal Submicrometer Spheres

Abstract

Canned heat: Inhibition of anisotropic crystal growth is critical for synthesizing semiconductor/metal spheres, but it is kinetically difficult to achieve in methods relying on conventional heating. Selective heating of colloidal nanoparticles by pulsed laser irradiation allows size-tailored semiconductor and metal submicrometer spheres to be synthesized.
