Digital linearization and cancellation of capacitive coupling for a scanning tunneling microscope
This article describes the development and test of a digital control loop, to control the tip-to-specimen distance in a scanning tunneling microscope. This digital controller performs a frequency-independent linearization of the gap-to-current relationship, as well as the compensation of the undesir...
