Abstract :
An accelerated iterative method for a self-consistent solution of the coupled Poisson-Schrodinger equations is presented by virtue of the Anderson mixing scheme. In this proposed method, the number of iterations is remarkably reduced at the cost of slightly longer computational time at each iteration. An example of a two-dimensional double-gate MOSFET is included, in which simulations with different device profiles and transport models are accelerated.
