Energy spectra and photoelectron work function from YBa2Cu3O7 high-T(sub c) superconductor
Abstract
The results are presented of the experiments on the JINR newly built instrument for the photoelectron spectroscopy by the time-of-flight method. The energy resolution achieved was 0.2-0.05 eV. The electron work function (phi) from three samples of polycrystalline high-T(sub c) superconductor YBa2Cu3O7 were measured to be phi = 5.5 +/- 0.2 eV. Spectra of photoelectrons in dependence on time and energy are given.
