Cavendish Laboratory : Pippard's model of the Fermi surface of copper
Cavendish Laboratory
<p style='text-align: justify;'>Colour photograph of Pippard's model of the Fermi surface of copper. Pippard's microwave experiments enabled the three-dimensional Fermi surface of copper to be inferred, the first time this had been done for any material. The Fermi surface lies in momentum space and many of a material's properties are determined by the behaviour of electrons in the vicinity of the surface.</p>
