Model of Laser-Induced Deposition on Semiconductors from Liquid Electrolytes

Abstract

A model for laser induced electrolytic deposition on a semiconductor surface is developed. The laser induces two effects in the surface: thermal heating, which results in a thermal potential, and the Dember effect in which excited electrons and holes diffuse at different rates. The model is compared with experiment, and the ring-shaped deposit discovered is reproduced in the calculation. Keywords: Deposition; Semiconductors; Laser induced; Liquid electrolytes; Dember effect; Electrons; Holes.
