Abstract: | An abrupt rise of the field electron emission (FEE) current from a high-temperature superconductor (HTSC) being in the normal
state has been detected. The current amplification with a factor reaching ∼106 occurs as an HTSC emitter is heated in the temperature range 110–170 K. The features of the temperature dependence of FEE
are discussed. Measured parameters of the effect observed are presented. Possible mechanisms of the process under consideration
are discussed.
