• regime |eV| < Φ, where for a rectangular barrier the simplified formula can be applied, with the electron mass m, the reduced Planck’s constant , and the thickness of the barrier d [30]. To apply the model to atomic-size contacts in which the current, I, rather than the current density, J, has to be

• with a variable intensity up to 3 mW onto the sample. The influence of thermal gradients onto atomic-size contacts usually causes geometry changes of the tips due to thermal expansion caused by the deposited energy. For our experiment we obtain from simulations that the distance change between the tips
