Abstract

A novel efficient method to calculate the ballistic quantum transport in two or three dimensional multi-terminal devices of arbitrary geometry, potential profile and number of leads has been presented. In this work we show that the method termed contact block reduction (CBR) allows calculation of not only the transmission function, but the electron density and density matrix of the device as well. The calculation costs are mainly determined by the size of the contact boundaries of the device.
