| 1. | The advantages of field emission technologies over alternative electron emission methods are:
|
| 2. | The thorium dopant in the electrodes greatly enhances their electron emission characteristics.
|
| 3. | However, a positive atomic ion may result from further Auger electron emission.
|
| 4. | The improvement arises because secondary electron emission for high-Z materials is enhanced.
|
| 5. | The lower the work function, the lower the temperature for electron emission.
|
| 6. | Cold cathodes sometimes have a rare earth coating to enhance electron emission.
|
| 7. | His work included field electron emission and photoemission studies of surfaces.
|
| 8. | Below the electron emission saturation limit the contactor acts as a bipolar emissive probe.
|
| 9. | Secondary processes include electron emission from the cathode and photoionization within the gas volume.
|
| 10. | Advanced surface interactions can be modeled, including user-defined secondary electron emission, sputtering, and surface charging.
