Abstract

We are interested on studying diffusion process of a half occupied clean surface. Our calculations are performed in the framework of lattice gas model using Monte Carlo simulation. We analyze the behavior of the relevant physical quantities as diffusion coefficient tracer and specific heat. We consider first JFN and second JSN neighboring repulsive interactions with the ratio R = JSN / JFN in the [0.1] range. We show that the second repulsive neighboring interactions induce an order/disorder transition for some critical values of R that affect the surface diffusion mechanism..
