摘要：

We have carried out angle-resolved photoemission Spectroscopy on single crystals of YBa2Cu3O6.9. The crystals were cleaved in situ, under ultra high vacuum while the sample stage was cooled to below 10°K. By observing the dispersion of the electron energy bands as they cross the Fermi energy, we have mapped the Fermi surfaces. There is reasonable agreement between the experimental results and the predictions of band structure calculations using the local density approximation, as well as with positron annihilation experiments. © 1990.
