title: Two-dimensional equilibrium surface roughness for dissociative dimer dynamics.
abstract: Equilibrium crystal surfaces, constrained to equilibrate by means of dissociative dimer deposition and evaporation, have anomalous global surface roughness. We generalize earlier results for one-dimensional interfaces to two dimensions. The global surface width scales with surface size L as W2 approximately equals ln[L/(ln L)(1/4)] instead of the conventional form W2 approximately equal to ln L. The surface roughening transition does not change in nature, but its location is subject to a large and slowly varying logarithmic finite-size-scaling shift.
