Langevin Equation for Diffusion of Molecules Adsorbed on Surfaces
(2010-09-07)
Starting from a classical mechanical model, a set of Langevin equations for the surface diffusion of adsorbed molecules is developed. In contrast to previous work, these Langevin equations take full account of the rotations ...
Stochastic model for surface diffusion of organic molecules
(2015-03-27)
A theoretical model for the diffusion of large molecules adsorbed on surfaces is developed. Starting from the classical equations of motion, a generalized non-Markovian Langevin equation for the center of mass diffusive ...
