Adjoint-based deviational Monte Carlo methods for phonon transport calculations
In the field of linear transport, adjoint formulations exploit linearity to derive powerful reciprocity relations between a variety of quantities of interest. In this paper, we develop an adjoint formulation of the linearized Boltzmann transport equation for phonon transport. We use this formulation for accelerating deviational Monte Carlo simulations of complex, multiscale problems. Benefits i...
متن کاملParallel Monte Carlo simulation of MBE growth
We present a parallel algorithm for Monte Carlo simulation of molecular beam epitazial growth (MBE) focusing on the software we have developed and the ezperiences gained. An eficient sequential method to do MBE simulation was developed that uses a single binary tree t o store the rates of occwence of all possible events at a given time. The challenge was to find a ioay to adapt this method to a...
متن کاملMonte Carlo Simulation of Hole Transport In
Abstrati-The transport properties of holes in Si, _ ,Ge, are studied with a Monte Carlo technique. If the strain is applied to the Si, _ ,Ge, channel, it raises the degeneracy of the heavy-hole and light-hole bands: for compressive strain, the heavy-hole band lies at a higher energy than the light-hole band, while for tensile strain, the order reverses, although it is technologically uncertain ...
متن کاملFull-dispersion Monte Carlo simulation of phonon transport in micron-sized graphene nanoribbons
We simulate phonon transport in suspended graphene nanoribbons (GNRs) with real-space edges and experimentally-relevant widths and lengths (from submicron to hundreds of microns). The full-dispersion phonon Monte Carlo (PMC) simulation technique, which we describe in detail, involves a stochastic solution to the phonon Boltzmann transport equation with the relevant scattering mechanisms (edge, ...
متن کاملEfficient simulation of multidimensional phonon transport using energy-based variance-reduced Monte Carlo formulations
We present a Monte Carlo method for obtaining solutions of the Boltzmann equation to describe phonon transport in microand nanoscale devices. The proposed method can resolve arbitrarily small signals (e.g., temperature differences) at small constant cost and thus represents a considerable improvement compared to traditional Monte Carlo methods, whose cost increases quadratically with decreasing...
