Mechanisms and kinetics of silicon atomic-layer epitaxy on silicon(001)2x1 and germanium(001)2x1
type: CreativeWork
description: Single-crystal Si films have been grown on Si(001)2x1 substrates by UV-photostimulated atomic-layer epitaxy (ALE) from Si$\sb2$H$\sb6.$ The ALE deposition rate R per growth cycle remains constant at 0.43 monolayers (ML), 1 ML = $6.8\times10\sp{14}$ cm$\sp{-2}$, over a wide range of deposition parameters: growth temperature (T$\sb{\rm S}$ = 180-400$\sp\circ$C), Si$\sb2$H$\sb6$ exposure, UV laser energy density, and number of UV laser pulses per cycle. A film growth model, based upon the results of adsorption/desorption measurements, film growth experiments, and Monte Carlo simulations, is used to describe the reaction pathway for the process.
