Thermally stimulated H emission and diffusion in hydrogenated amorphous silicon
T. A. Abtew, F. Inam, D. A. Drabold
We report first principles ab initio density functional calculations of hydrogen dynam- ics in hydrogenated amorphous silicon. Thermal motion of the host Si atoms drives H diffusio…

Hydrogen dynamics and light-induced structural changes in hydrogenated amorphous silicon
T. A. Abtew, D. A. Drabold
We use accurate first principles methods to study the network dynamics of hydrogenated amorphous silicon, including the motion of hydrogen. In addition to studies of atomic dynamic…
