Abstract

Diffusion of deuterium in diamondlike carbon films with different Si contents deposited by a pulsed arc discharge method in deuterium atmosphere was studied. The concentration profiles of D were measured by secondary-ion-mass spectrometry and elastic-recoil-detection techniques. A model is proposed to describe the experimental depth profiles. Diffusion, detrapping, and trapping of D were taken into account in this model. Diffusion coefficients obtained for nontrapped D resulted in activation energies of 1.5±0.2, 0.7±0.2, 0.6±0.2, and 1.2±0.2 eV for samples containing 0, 6, 15, and 33 at.% of Si, respectively.
