First Observation of Light-controlled Self-assembly of Gallium Nanoparticles with Narrow Size Dispersion

Abstract

Several laser-based techniques for producing metal particles of uniform shape and size have been reported but these all rely on high power pulsed lasers and are almost all based on postgrowth manipulation of particle sizes and shapes. The growth process that we report here, controls the shape and size of particles as they form, through non-thermal processes, using a low- power (~few mW) infrared diode laser.
