报告摘要：

The operation of electronic devices that are fabricated at the nanoscale is governed by quantum mechanics. To compute the electrical characteristics of such devices, one can use the non-equilibrium Green’s functions formalism and tight binding theory. These theoretical descriptions go beyond the classical description of electron transport and are therefore capable of capturing the physics of nanoscale devices. In this talk I will introduce these two methodologies and show how they can be applied to a variety of novel systems, from semiconductors to topological materials. I will present a tight binding model for the two-dimensional allotropes of bismuth, simulations of transverse magnetic focusing in gallium arsenide, and current-voltage characteristics of nanowires in phosphorus doped silicon.
