“…The conceptual simplicity of its paramagnetism encouraged confidence in the accuracy of existing band structure calculat~ons. 7 The agreement between Fermi surface measurements 8 and the ab initio theoretical results suggested that the band structure for copper was understood. The result of these ARPES investigations was a qualitative understanding of valence-band photoemission.…”

“…Our model uses the anisotropic band structure of copper EðkÞ [15]. Moreover, an electron wave can additionally favor only a few specific directions when traveling over a long distance, a so-called focusing effect already studied for other systems [10,[16][17][18], intimately relates to specific features of the band structure.…”

“…We have found that the specific shape of the subsurface nanocavity reflecting the electrons cannot explain all the details of the observed pattern. The band structure of copper 10 and the phenomenon of focusing of hot electrons 11,12 connected to it play an important role in the observed spatial variation of the conductance maps. We developed a model taking into account injection, propagation, reflection and interference of electrons, as well as the anisotropy of electronic properties in Cu.…”

Argon-filled nanocavities embedded in a single crystal of copper near the surface reflect electrons and induce a quantum well ͑QW͒ between the nanocavity and the atomically flat Cu͑001͒ surface. The spatial variation of conductance at the surface above the nanocavity was studied by scanning tunnelling microscopy and/or spectroscopy. Interference features were observed over several nanometers at some locations on the surface. In the ͓100͔ and ͓010͔ directions, the interference fringes propagate over longer distances up to tens of nanometers. In addition to these spatially resolved features, the conductance reveals an oscillatory behavior as a function of energy of injected electrons. A model taking into account the specific shape of the nanocavity, as well as the band structure of copper, allows us to simulate the spatial variation of the conductance in close agreement with the experiment. The modeling demonstrates that not only the specific shape of the subsurface nanocavity reflecting electrons is crucial to explain the observed pattern, but also the anisotropy of the band structure and the phenomenon of focusing of hot electrons connected to it. Our approach opens up opportunities to examine buried nano-objects with scanning tunneling microscopy, and also to study how the anisotropy of a crystal influences the spatial variation of QW properties.
