The diffusion of hydrogen in amorphous silicon formed by ion implantation was studied using real-time elastic recoil detection analysis. An activation energy for H diffusion of 1.82eV was determined in a single ramped anneal. This activation energy was consistent with diffusion studies in the high H concentration regime. The low beam current employed was found to have a negligible influence on the H diffusion within the sensitivity of the measurement. Further refinements for increased accuracy of this technique were considered.
