Abstract
A new model for Monte Carlo simulation is proposed for one-dimensional electron gases. In the model, electron energy and momentum are treated as independent variables, and the Wigner distribution function f(k, omega ,t) is simulated instead of the semiclassical distribution function f(k,t). Using this method, the transport responses of one-dimensional electron gases in a quantum wire at room temperature are evaluated in which electrons are interacting with optical phonons only, and the results reveal that the electron temperature increases monotonically with applied electric field without showing anomalous carrier cooling.
