Methods, devices and systems for scanning tunneling microscopy control system design

摘要

Methods, devices, and systems for controlling a scanning tunneling microscope system are provided. In some embodiments, the methods, devices, and systems of the present disclosure utilize a control system included in or added to a scanning tunneling microscope (STM) to receive data characterizing a tunneling current between a tip of the scanning tunneling microscope system and a sample, to estimate, in real-time, a work function associated with the scanning tunneling microscope system, and to adjust, by a control system, a position of the tip based on an estimated work function. Associated systems are described herein.
