## A set of parameters for the three-band Hubbard model is determlned by comparison of Quantum Monte C~lo results with experimental values for the charge transfer gap. With the obtained parameter set we have calculated the spectral function A(k,t~) for the one-particle Green's function. We find ve
## Abstract We present a threeβdimensional (3D) semiβclassical ensemble Monte Carlo model newly developed to simulate a variety of nanoelectronic devices. The characteristics of the 3D model are compared with the widely used twoβdimensional (2D) models. The advantages of our model, in terms of accu
