Domain and Subband decomposition approach for 2D simulation of quantum transport phenomena∗
نویسندگان
چکیده
We present a domain decomposition technical for computing the quantum transport phenomena in complex nano-structures. In regular sub-domains, the subband decomposition method is applied, while the finite difference method is used on small irregular sub-domains where the subband decomposition is not applicable. This new approach preserves the efficiency of the original subband decomposition method, with a minor increase of the computational cost. Results of numerical experiments demonstrate the efficiency and accuracy of this method.

Ultra-short pulse is a promising technology for achieving ultra-high data rate transmission which is required to follow the increased demand of data transport over an optical communication system. Therefore, the propagation of such type of pulses and the effects that it may suffer during its transmission through an optical waveguide has received a great deal of attention in the recent years. We...
