Our recent paper, entitled “High signal-to-noise ratio differential conductance spectroscopy” by Hamed Alemansour et al. published in the Journal of Vacuum Science and Technology B was awarded an Editor’s Pick.
In a LinkedIn post, the Editor, Eray Aydil, describes it as “STM on steroids: Imaging capability of the STM combined with with scanning tunneling spectroscopy with a feedback loop that enables capturing a higher quality dI/dV image.” The paper describes a new method which allows for I-V spectroscopy data to be collected while maintaining the tip height above the surface with the tunnel current feedback loop. Combined with creep correction to prevent xy movement, this promises the ability to obtain more accurate spectroscopy, and more rapidly.
We believe that this is an important new development of STM technology and demonstrates the value of our ongoing collaboration between Zyvex Labs and UT Dallas, which is funded by a research grant from the DOE Advanced manufacturing Office.
