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.
