Abstract:
The ballistic motion of kinetically hyperthermal clusters on corrugated potential energy surfaces is studied by molecular dynamics simulations. Under pulsed laser deposition conditions, such clusters are generated due to the supersaturation flux and nonthermal energies of the incident species, a fraction of which is transferred to the clusters. This energy transfer, together with the flattening of the potential energy surface due to the cluster inner bonds, causes a lengthening of the ballistic paths as the cluster size increases. These results help explain the enhancement of growth kinetics by pulsed laser deposition.

Carrier Transport
Drift Current:
The drift of charge carriers is started by an external electric field (E). Charged particles, such as electrons and holes, experience an acceleration between collisions with lattice atoms. For electrons, this results in a drift velocity (vd) given by:
Carrier Generation and Recombination
This process is given by the generation rate G and is efficient due to the conservation of momentum between the valence band maximum and conduction band minimum.
