Thermal-field electron emission W(100)/ZrO cathode: facets versus edges
Original language description
The tungsten cathode in the thermal-field emission (TFE) regime can achieve significantly higher angular current density in comparison with the Schottky cathode. The Schottky emission regime is located between the thermal emission regime and the cold field emission regime. The typical operation electric field is 0,1 - I V/nm and tip radius varies from 0.3 to 1.0 im . The thermal-field regime is located between the Schottky regime and the cold field emission regime. In the cold field emission regime theelectron tunnelling is a dominant mechanism due to the electric field higher than 1 V/nm. The TFE is a combination of the field supported thermal emission and the field emission under the higher electric field. The radius of the thermal-field emitter should be lower in comparison with the Schottky emitter.
