Abstract

The direction of the drift of adatoms induced by direct-current (DC) heating of Si(111)-(1×1) surfaces was studied from shape changes of a rectangular groove that was made by a focused ion beam (FIB) apparatus. It was found that the drift direction is to the current direction irrespective of the temperatures of the three ranges where DC-induced step-bunching behavior reverses twice. The result clearly shows that reversals of the current-induced step bunching are not due to reversals of the effective charge on silicon adatoms, but due to changes in the mechanism of step bunching.
