We calculate a deposition process of hydrogenated amorphous silicon (a-Si:H) films on a silicon (100) substrate by reactive force-field molecular dynamics simulations. The influences of (a) substrate temperatures and (b) coverage of hydrogen atoms on the substrate on the adsorption probability are investigated, and it is found out that (a) the adsorption probability is almost constant for SiH 2 and SiH 3 , but decrease with increase in the substrate temperature for SiH 4 , (b) it decreases with the increase in hydrogen coverage. |
