摘要

The molecular dynamics (MD) method, with David Cai's electronic stopping power model applied, is successfully applied to simulate implantation into HfO_2. For the first time, a reliable fitting value of the single electron radius in the electronic stopping power model is given for boron, arsenic and phosphorus implantation into HfO_2. Excellent agreement between simulation results and SIMS data has been obtained over the energy range of 3-40 keV using the derived fitting value. Our simulation results are found to be in better agreement with the SIMS data than those obtained by means of the traditional simulator TSUPREM4.
