× )R30° structural formation by HBO2 molecular irradiation onto a Si(111)-7×7 surface at ∼750 °C, B atoms interacted with each other to form chains from the beginning, and a ( × )R30° structure consisting of Si and B atoms was formed. The observed result is completely different from the ( × )R30° structural processes induced by other group III atoms; in general, when metals such as Al are deposited on a Si(111)-7×7 surface, large 7×7 and ( × )R30° structure domains exist separately. With an increase in the amount of the B component to about half the number of adatoms, B atoms formed a network with the same ( × )R30° phase, resulting in the formation of an ordered ( × )R30° structure. Off-phase disordered areas remaining on the surface were limited to the areas occupied by Si atoms. The obtained results indicate that the interaction caused by B atoms plays an essential role in the formation process of the ordered ( × )R30° structure of this surface.
