WebThe tunneling current is measured from the tip. The tip sits at the end of a piezo tube scanner (with 4 quadrants ± x and ± y on the outside, and a single electrode for z on the inside), which can control its motion with sub-Angstrom precision in 3 directions. So we can measure tunneling current as a function of 4 variables: x, y, z, and V.
