Towards a Revised Monte Carlo Neutral Particle Surface Interaction Model

The components of the neutraland plasma-surface interaction model used in the Monte Carlo neutral transport code DEGAS 2 are reviewed. The idealized surfaces and processes handled by that model are inadequate for accurately simulating neutral transport behavior in present day and future fusion devices. We identify some of the physical processes missing from the model, such as mixed materials an...

Quasicontinuum Monte Carlo: A method for surface growth simulations

We introduce an algorithm for treating growth on surfaces which combines important features of continuum methods ~such as the level-set method! and kinetic Monte Carlo ~KMC! simulations. We treat the motion of adatoms in continuum theory, but attach them to islands one atom at a time. The technique is borrowed from the dielectric breakdown model. Our method allows us to give a realistic account...

Monte Carlo simulations of surface reactions

Numerical simulations based on the Monte Carlo method offer a powerful approach for detailed studies of complex reaction sequences, such as those associated with heterogeneous catalysis. In this article, we summarize some of the recent work based on discrete models for irreversible surface reactions. Particular emphasis is placed on kinetic phase transitions, bistability, and oscillatory (nonst...
