The non-equilibrium Green’s function approach, an emerging simulation technique for novel devices

Jesse Vaitkus, RMIT

We use non-equilibrium Green’s functions, tight-binding and effective models to understand transport in a range of nanoscale devices. In 2019, this has included developing a new tight-binding model for low-dimensional allotropes of Bismuth (with the Monash node), studying the effects of spin-orbit coupling in two-dimensional electron gases (with the UNSW node), and Majorana fermions in nanowires. In addition, we have recently been studying conduction in quantum spin hall insulators in the presence of magnetic impurities.
