概要
- 論文の詳細を見る
To characterize the electronic properties of superconducting YBa_2Cu_3O_7, its work function φ has been measured by two different methods. From the photoelectric and electrical determinations, it is shown that φ of polycrystalline YBa_2Cu_3O_7, is close to 4.0 eV. The relatively high work function of YBa_2Cu_3O_7, for its low electron density implies that a strong exchange-correlation potential exists in the bulk. Systematic studies are necessary in order to determine whether or not the work function is a useful parameter for the new high-T_c superconductors as well as for the conventional ones.
