Diffusion of small two-dimensional Cu islands on Cu(111) studied with a kinetic Monte Carlo method

Diffusion of small two-dimensional Cu islands containing up to 10 atoms on Cu 111 has been studied using the newly developed self-learning Kinetic Monte Carlo SLKMC method which is based on a database of diffusion processes and their energetics accumulated automatically during the implementation of the SLKMC code. Results obtained from simulations in which atoms hop from one fcc hollow site to ...

Self-learning kinetic Monte Carlo method: Application to Cu(111)

We present a method of performing kinetic Monte Carlo simulations that does not require an a priori list of diffusion processes and their associated energetics and reaction rates. Rather, at any time during the simulation, energetics for all possible singleor multiatom processes, within a specific interaction range, are either computed accurately using a saddle-point search procedure, or retrie...

Parallelization of the Two-Dimensional Wigner Monte Carlo Method

Conducting Wigner Monte Carlo simulations remains highly challenging primarily due to the method’s critical annihilation step, required to counter-balance the continuous generation of particles to keep the simulation computationally feasible. The memory demands of the annihilation algorithm itself is proportional to the dimensionality and resolution of the phase space represented in the simulat...

Introduction to the Kinetic Monte Carlo Method

Monte Carlo refers to a broad class of algorithms that solve problems through the use of random numbers. They first emerged in the late 1940’s and 1950’s as electronic computers came into use [1], and the name means just what it sounds like, whimsically referring to the random nature of the gambling at Monte Carlo, Monaco. The most famous of the Monte Carlo methods is the Metropolis algorithm [...

First-passage kinetic Monte Carlo method.

We present an efficient method for Monte Carlo simulations of diffusion-reaction processes. Introduced by us in a previous paper [Phys. Rev. Lett. 97, 230602 (2006)], our algorithm skips the traditional small diffusion hops and propagates the diffusing particles over long distances through a sequence of superhops, one particle at a time. By partitioning the simulation space into nonoverlapping ...
