A New Automated Preparation Process by Electrochemical Corrosion of STM Tungsten Tips

摘要

Scanning tunneling microscope (STM) is one of the most important instruments in the field of two-dimensional(2D) materials science while the STM tip is one of the most important parts in STM. Thus, we exhibit a new automated preparation process by electrochemical corrosion of STM tungsten(W) tips based on analog circuit technology in this paper. And the new preparation process is easy and reliable and can save time of researchers. Here, we will elaborate the preparation process and how the system works. In all, we will open up a new road in the field of preparation of STM tips.
