Non-equilibrium Green’s functions (NEGF) method in matrix form is presented and applied to model transport problems for 1D and 2D conductors using Huckel approximation in the «bottom – up» approach of modern nanoelectronics. General method to account for electric contacts in Schrödinger equation is given. Elastic and spin dephasing modeling and account for non-coherent processes are also discussed
