Rather high ion doses 1×10<sup>13</sup> cm<sup>-2</sup> were used in order to have more chances to get damaged images. Not only atomic structures of the original surface, but also arrangements on the elevated regions even at the bottom of the craters are clearly shown in the STM images. In general, there is a one-to-one correlation between the number of ion impacts and the number of craters.展开更多
