摘要
masha_19957@mail.ru Abstract. Influence of the initial Si surface state on the rate of ripple nucleation under bom-bardment with low-energy O2+ ions was investigated. It was found that the creation of a defect area in the Si near-surface layer or the creation of the initial surface relief by ion bombardment with a focused Ga+ ion beam facilitates a significant acceleration of the ripple nucleation on the Si surface during subsequent irradiation with an O2+ ion beam.
