Anomalous volt-ampere characteristics of vacuum diodes with metallic single-crystal electrodes
Anomalies have been found on the initial portion of the volt-ampere (V-A) characteristic of a diode with a single-crystal tungsten cathode. The anomalies appear on the V-A characteristic, starting at some threshold value of the cathode temperature Τ = ΘΎΕ, ΘΎΕ which is the characteristic thermal emission temperature. It is assumed that the effect is caused by the emission of electrons formed during the recombination of thermal defects.
