Abstract

Proton and deuteron double resonance methods have been used to study the structure of high quality plasma-deposited a-Si:H,D and a-Ge:H,D films. The micro-structure of the a-Si is dominated by nanovoids with dimension <3 Å while the a-Ge shows many larger microvoids. We have observed new proton HD multiple echoes in the films by using a three pulse sequence double resonance method. The new echoes imply that HD molecules in a-Ge principally are located in large microvoids, which is not the case in high quality a-Si.
