摘要：

An STM system capable of measuring the tunnel gap separation (s) dependence of tunnel current (I), i.e., the I-s characteristics, was constructed. The I-s characteristics were successfully measured by sweeping the set current, instead of modulating the tip position. It was found that the tunnel current could be detected over a separation range of 1 nm. Furthermore, a new imaging technique, tunnel gap imaging, which maps out the lateral distribution of the 1-s characteristics, is proposed and realised.
