Field Emission from Low Barrier Surface Cathodes

V. Semet, Ch. Adessi, Vu Thien Binh

Open publisher page 2 citations

Abstract

A systematic study was done in order to relate the J-F characteristic variation with the three emission mechanisms, tunnelling, thermionic and ballistic. All three are now effective during the field emission from surface with low work function. Empirical relations will be given to extract some cathode properties from the measured J-F characteristics
