Theory of real space imaging of Fermi surfaces
arXiv:1010.2112 · doi:10.1103/PhysRevB.83.035427
Abstract
A scanning tunneling microscope can be used to visualize in real space Fermi surfaces with buried impurities far below substrates acting as local probes. A theory describing this feature is developed based on the stationary phase approximation. It is demonstrated how a Fermi surface of a material acts as a mirror focusing electrons that scatter at hidden impurities.
