The Roughening Transition of Vicinal Surfaces
Various vicinal surfaces of copper have been studied:
At the same temperature the roughness increases with the distance between steps as a result of the weakening of the step-step interaction.
Changing the terrace structure from (100) to (111) does not significantly affect the roughness. — Steps parallel to the loosely packed direction  are very much rougher than those parallel to the close-packed direction .
Freezing of the roughness due to low surface mobility always occurs below room temperature.
The large terrace surface Cu(1,1,11) deviates from the prediction of the Kosterlitz-Thouless model. A tentative explanation is given.
