| 1. | The elecrons can be provided by thermionic emission and / or secondary emission.
|
| 2. | The incandescent regions contribute free electrons via thermionic emission, and ( easily ionized ) metal vapor.
|
| 3. | Plasma is produced via discharge from a barium-oxide coated cathode, which emits electrons via thermionic emission.
|
| 4. | Current in the arc is sustained by thermionic emission and field emission of electrons at the cathode.
|
| 5. | This " shadow " led to discovery of Thermionic emission, the basis for Vacuum tubes and electronics.
|
| 6. | Thermionic emission can be used to measure the work function of both the hot emitter and cold collector.
|
| 7. | In Bethe's theory, the current is limited by thermionic emission of electrons over the metal semiconductor potential barrier.
|
| 8. | Hot metal will emit electron via Thermionic emission . talk ) 17 : 48, 18 November 2008 ( UTC)
|
| 9. | Cold cathode lamps are generally less efficient than thermionic emission lamps because the cathode fall voltage is much higher.
|
| 10. | In this case, the emission current is regulated by the thermionic emission process, given by the Richardson Dushman equation.
