摘要：

Fluctuation of a step of a crystal in the vapor growth condition, where surface diffusion of adsorbed atoms is essential, is studied with a linear stochastic theory. With an asymmetry in step kinetics, the step becomes smooth when it recedes, whereas it becomes very rough when it grows near the Mullins-Sekerka instability point. These effects are confirmed by Monte Carlo simulations.
