It is not a real surface but a picture of how the electrons in a metal behave. These pictures explain such properties of metals as luster, ductility and the conduction of electricity and heat ...

A Fermi liquid is a theoretical model that describes the behavior of interacting electrons in metals and other condensed matter systems ... is determined by the density of states at the Fermi level ...

This is in great part due to a phenomenon known as Fermi level pinning, which entails a fixation of the energy level at the interface between a metal and semiconductor. Researchers at the Korea ...
