APPLICATIONS OF FIRST PRINCIPLES SIMULATIONS OF QUANTUM TRANSPORT

I will describe the TranSIESTA method to calculate the electronic transport properties of
nanoscale devices out of equilibrium. The method is based on a Non-Equilibrium Green's
Function formulation of the transport problem, together with a Density Functional Theory
description of the electronic potential. I will briefly discuss the basic features of the method,
and also its limitations and shortcomings, and then I will mainly present examples of
different applications in the context of Scanning Tunneling Spectroscopy (STS), molecular
bridges, and solid state ferroelectric tunneling junctions.
