WebScanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS) are the most powerful techniques for revealing the topographic structures of the surfaces [46,47]. These techniques are also can be used to measure defects on or slightly below surfaces. Weblines of STM images and the corresponding side view on the bottom. STM image shows high tunneling location (a) at center of two nuclei and (b) at the top of each nucleus. STM Measuring Modes STM can be operated in three major operation modes: (1) imaging mode, (2) spectroscopy mode, and (3) manipulation mode. There are two imaging modes: …

WebSeveral types of spectroscopy are also available with STM and it is called Scanning Tunneling Spectroscopy (STS). The most common STS is to measure the tunneling current (I) as a function of the sample-probe bias potential(V), keeping the sample-probe distance.
