... by moving the tip in the x and y directions while using a feed-back loop in order to hold the current constant. In order to achieve such a constant current, the tip has to be moved in the z direction to follow the atomic contours on the surface. This means that if the z motion is mapped as a functi ...

For example, thermodynamics is a phenomenological theory which relies on the assumption that the system under consideration consists of a large (approximated by infinitely many) number of particles. When this limit - the so-called therm ...

... From the formula we see that Ptu n exp(2a) , or, Ptun 1 e . The tunnelling probability falls exponentially (very strongly) with increasing barrier width. The factor most strongly favouring tunnelling will be a thin barrier. The tunnelling probability also goes exponentially with the square root ...
