✦ Synopsis

The kinetics for the non-dissociative adsorption of gas phase molecules on a spatially homogeneous square lattice was simulated using a Monte Carlo method which accounts for the existence of an extrinsic precursor state. We find the sticking coefficients obtained using our simulations to be lower than those calculated using the equation derived by Kisluik, and show that islanding of the adsorbates on the surface and site revisiting in the precursor state account for the observed discrepancies.

## Abstract We present a three‐dimensional (3D) semi‐classical ensemble Monte Carlo model newly developed to simulate a variety of nanoelectronic devices. The characteristics of the 3D model are compared with the widely used two‐dimensional (2D) models. The advantages of our model, in terms of accu

The exchange kinetics of polymers adsorbing on a solid surface is extensively studied by dynamic Monte Carlo simulations. A model employed simulates a semidilute polymer solution placed in contact with a solid surface that attracts polymer segments by the adsorption interaction (v s ). The exchange
