In a conserved system step wandering takes place with step-up adatom drift. Repulsive interaction between steps is found indispensable for the instability. Monte Carlo simulation with a strong repulsive step interaction confirms the result of linear stability analysis, and further shows that in-phase step wandering produces straight grooves. Grooves widen as their amplitudes increase in proportion to the square root of time., 金沢大学理学部}, pages = {125408-1--125408-7}, title = {Repulsion-mediated step wandering on a Si(001)vicinal face}, volume = {67}, year = {2003} }
