Abstract

Avalanche concentration, a rapid long-range accumulation of particles around a laser spot in a liquid sample, is demonstrated and characterized for VO2 nanorods. The effect is found to be driven by a convective flow in the sample, caused by efficient heating of VO2 nanorods that transition from insulator to metal within the laser spot.
