The Atomistic Green's Function Method: An Efficient Simulation Approach for Nanoscale Phonon Transport

Deviational Phonons and Thermal Transport at the Nanoscale

We present a new method for simulating phonon transport at the nanoscale. The proposed approach is based on the recently developed energy-based deviational Monte Carlo method by the authors [Phys. Rev. B 84, 205331, 2011] which achieves significantly reduced statistical uncertainty compared to standard Monte Carlo methods by simulating only the deviation from equilibrium. Here, we show that und...

Nanoscale Studies on Aggregation Phenomena in Nanofluids

Understanding the microscopic dispersion and aggregation of nanoparticles at nanoscale media has become an important challenge during the last decades. Nanoscale modeling techniques are the important tools to tackle many of the complex problems faced by engineers and scientists. Making progress in the investigations at nanoscale whether experimentally or computationally has helped understand th...

Monte Carlo Transport and Heat Generation in Semiconductors

Understanding transport and energy use in nanoscale devices is essential for the design of low-power electronics and efficient thermoelectrics. This chapter examines transport physics and the electron-phonon interaction in the context of Monte Carlo simulations, which treat electrons and phonons with comparable attention to detail. The Monte Carlo method is described in depth, including scatter...

Surfactant-free synthesis of Bi2Te3-Te micro-nano heterostructure with enhanced thermoelectric figure of merit.

An ideal thermoelectric material would be a semiconductor with high electrical conductivity and relatively low thermal conductivity: an "electron crystal, phonon glass". Introducing nanoscale heterostructures into the bulk TE matrix is one way of achieving this intuitively anomalous electron/phonon transport behavior. The heterostructured interfaces are expected to play a significant role in ph...
