Figure 1: Schematic of the tunnelling process.
From: Sensing the quantum limit in scanning tunnelling spectroscopy
(a) Schematic drawing of an STM tunnel junction consisting of tip and sample. The equivalent circuit diagram is represented by a tunnelling resistor RT and the junction capacitance CJ. (b) Schematic energy diagram showing the energy loss of an electron tunnelling in an STM from the tip to the sample. Interacting with the surrounding environment, the electron loses energy according to the probability given by the P(E)-function. The FWHM is indicated with the values found in this work.
