Evidence of Schottky emission in scanning tunneling microscopes operated in ambient air

We demonstrate that the electron transfer mechanism in scanning tunneling microscopes operated in air follows the Schottky equation. Schottky emission dominates electron transfer mechanism in microscopes operated in air because of low effective potential barrier heights. This is supported by currents and gap distances that are larger than when tunneling is the predominant electron transfer mechanism.
