Abstract:

Silicon and its native oxide SiO2are the most commonly used materials in semiconductor device technology. After decades of research in this field, details of the initial oxidation and the subsequent O migration and amorphization are still a subject of interest. In this paper, we present a multiscale modeling approach to investigate the oxidation process of a Si(100) surface. Starting from the adsorption and dissociation of single O2 molecules, we further extended our investigations towards the initial oxidation of the first Si layer and subsequent O migration. Finally, we construct a realistic model of a Si/SiO2 interface consisting of around 5000 atoms. The employed simulation techniques used in this study range from density functional theory (DFT) to density functional based tight binding (DFTB) to classical molecular dynamics (MD).
