摘要
Using quantum mechanical methods that include the full band structure of Si and SiO2 and a selfconsistent potential, we study tunneling through ultrathin oxides. Limitations of the effective-mass approximation (EMA) are investigated. In particular, we obtain good agreement between calculated and measured tunneling current densities for a n-poly-Si/SiO2/p-Si MOS capacitor.
