Abstract

In this paper an newly developed numerical approach, which includes quantum effects into electromagnetic system analysis, was introduced to analyze nano-scale electronic devices. The numerical method uses an extended finite-difference time-domain (FDTD) technique to solve the Maxwell´s equations, combined with Schrdinger equation for quantum effects in those devices. Electron tunneling current through a potential barrier was calculated by this method and good agreement between the extended FDTD method and the analytical solution has been achieved. More realistic nano devices are expected to be included in future circuit analyses.
