Atomistic NanoTransport (ANT) comprises a series of codes designed to compute electronic quantum transport with a broad range of applicability in nanoelectronics. ANT.Gaussian (or ANT.G for brevity) relies on the popular quantum chemistry code GAUSSIAN03/09 code with which interfaces in a seamless manner. Straightforwad use of ANT.G include the computation of the zero-bias conductance (or, alternatively, the electrical current under an applied bias voltage) of a variety of nanoscale systems...
