Fermi surface determination from wavevector quantization in LaSrCuO films
We have observed the wavevector quantization in LaSrCuO films thinner than 12 unit cells grown on SrTiO3 substrates. Low energy dispersions were determined in situ for different photon energies by angle resolved photoemission spectroscopy. From the wavevector quantization, we extract three dimensional dispersions within a tight-binding model and obtain the Fermi surface topology, without resorting to the nearly free-electron approximation. Such method can be extended to similar confined electron nanostructures.
