Multiparticle tunneling during field emission from YBa2Cu3Or-δ
- 1. Leningradskij Ehlektrotekhnicheskij Inst., Leningrad (USSR)
Description
Electron tunneling to vaccuum from YBa2Cu3Or-δ metal ceramics is considered. The investigation is aimed at studying the quantity of elementary act and statistics of autoelectron emission (AE) which means act distribution according to their quantity. Multielectron AE acts from Y-Ba-Cu-O are detected for the first time within 4.2-300K interval. Observation of multiparticle acts at T>Tc indicates, that AE multielectron character is not conditioned by superconducting state feature, but reflects the source properties of metal ceramics. It is shown that the relative share of pair tunneling reaches 10%, and the share of three-electron and four-electron acts is about 1% and 0.2% respectively
