Oxide-field dependence of electron injection from silicon into silicon dioxide

The problem of electron injection from silicon into silicon dioxide is considered by means of a physical approach based on a simple model that provides good agreement with experimental data for MOS structures. The model implements the calculation of the electron energy distribution at the Si-SiO/sub 2/ interface by means of an efficient nonlocal algorithm, thus making possible a consistent treatment of the tunneling of hot electrons across the oxide. The oxide-field dependence of electron injection is addressed and the relationship between barrier lowering and electron energy distributions is discussed.<
