Title:

Abstract:

The impressive progress of semiconductor fabrication technology pushes the devices to the scale where quantum effects play an important role. In this talk, the hierarchy models for carrier transport in semiconductorbased on classical mechanics and quantum mechanics will be reviewed. Non-equilibrium Green function(NEGF) method and Wigner distribution method are the most popular methods in describing the quantum transport in nano-scale semiconductor devices. These two methods are used to simulate the current-voltage property for two typical nano-scale device: MOSFET(Metal-Oxide-semiconductor field effect transistor) and RTD (Resonant Tunneling Diode).
