В рамках концепции «снизу – вверх» наноэлектроники рассматривается метод неравновесных функций Грина (НРФГ) в матричной формулировке и применение его к модельным транспортным задачам 1D и 2D проводников в хюккелевском приближении. Сформулирован общий метод учета электрических контактов в уравнении Шредингера. Рассматриваются модели упругой дефазировки и спиновой дефазировки, учет некогерентных процессов с использованием зонда Бюттекера
