Resumen:
The wetting transition in a two-dimensional Ising model with a free
rough surface at which a boundary magnetic field acts is studied using
Monte Carlo simulations. In order to generate such rough surfaces we
have used a simple one-dimensional solid-on-solid model. Apart from the
basic thermodynamic quantities, such as susceptibilities, total average
magnetizations, heat capacities, we have also recorded two
magnetization distribution functions. The final results have been
obtained by averaging simulation data over several replicas of the
system of the same surface roughness. It has been shown that the
wetting transition is located at a lower surface field than in the
model with flat surfaces and that the critical value of the surface
field decreases when the surface roughness becomes higher.
