| Sumario: | Several stochastic processes corresponding to the physical solid-on-solid (SOS) deposition problem were analyzed. It was shown that the smoothing procedure could actually be applied to a large class of SOS deposition models, but the final linearization required the saturation of the roughness. It was observed that the evolution of the roughness with time is insensitive to most features of the stochastic process if exception is made for the conditional flux and variance of the model. The results show that although all the models studied belong to the same universality class, some relevant features such as the final surface roughness are reproduced only for models within a restricted class determined by sharing the same mean and variance. |
