Abstract

We report on STM studies of a Si(111)-(7 × 7) surface with subatomic resolution. STM images with double atomic features due to the contribution of two dangling bonds of the silicon apex atom were measured at different bias voltages and tunnelling currents. The results of experiments reveal strong dependence of the subatomic features shapes on the gap resistance and the bias voltage polarity. © 2008 IOP Publishing Ltd.
