✦ Synopsis

A Monte Carlo simulation for the heterogeneously catalyzed oxidation of CO on diffusion limited aggregation clusters is introduced. Kinetic phase transition points which appear in this reaction system are studied as a function of the system parameters. Both the 0 poisoning transition at y, and the CO poisoning transition at y, are found at very low values and they are second-order transitions. This holds even in the presence of CO diffusion. The results will be compared with simulations which were performed on regular and other fractal surfaces. The strong influence of the lattice structure is discussed in detail.

We performed a simulation of a cluster of five water molecules at 300 K using an ab initio potential. In our first study, the interactions were calculated at the U Ž .

## 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
