Abstract:
A model for surface growth with some of the features of molecular-beam epitaxy is proposed and investigated.
Particles are deposited randomly on a one-dimensional substrate and the surface relaxes
through diffusion processes, which obey detailed balance. The model undergoes a phase transition from
a rough phase to a grooved phase. Both phases display scaling in space and time, with equal exponents.
We also propose a Langevin equation which should describe this growth process and show that this equation
contains an infinite number of relevant terms.
