Abstract

Diffusion of hydrogen in zinc oxide was investigated during exposure to ²H plasmas. Optical properties were measured using photoluminescence spectroscopy at variable temperatures, with a He-Cd laser as the excitation source. Hydrogen was found to exhibit a very rapid diffusion in ZnO when incorporated by plasma exposure, with an estimated value for D of 8.7×10^-10 cm²/VS at 300 °C. The activation energy for diffusion was indicative of interstitial motion.
