Quantum Phonon Transport in Nanomaterials: Combining Atomistic with Non-Equilibrium Green’s Function Techniques

The Atomistic Green’s Function Method for Interfacial Phonon Transport

The atomistic Green’s function method (AGF) has emerged as a useful tool to study phonon transport across interfaces. A comprehensive review of developments in the AGF method over the last decade is provided in this chapter. The content includes a discussion of the fundamentals of a Green’s function starting from a continuum viewpoint and extending it to the atomistic regime. Comprehensive deri...

Non-equilibrium quantum dots: transport

The electronic transport through three-dimensionally confined semiconductor ’quantum dots’ is investigated and analyzed. The spectrum corresponds to resonant tunneling from laterally confined emitter contact subbands through the discrete three-dimensionally confined quan tum dot states. Momentum non-conservation is observed in these structures.

Boundary treatments in non-equilibrium Green's function (NEGF) methods for quantum transport in nano-MOSFETs

Non-equilibrium Green’s function (NEGF) is a general method for modeling non-equilibrium quantum transport in open mesoscopic systems with many body scattering effects. In this paper, we present a unified treatment of quantum device boundaries in the framework of NEGF with both finite difference and finite element discretizations. Boundary treatments for both types of numerical methods, and the...
