electron emission การใช้

• The advantages of field emission technologies over alternative electron emission methods are:
• The thorium dopant in the electrodes greatly enhances their electron emission characteristics.
• However, a positive atomic ion may result from further Auger electron emission.
• The improvement arises because secondary electron emission for high-Z materials is enhanced.
• The lower the work function, the lower the temperature for electron emission.
• Cold cathodes sometimes have a rare earth coating to enhance electron emission.
• His work included field electron emission and photoemission studies of surfaces.
• Below the electron emission saturation limit the contactor acts as a bipolar emissive probe.
• Secondary processes include electron emission from the cathode and photoionization within the gas volume.
• Advanced surface interactions can be modeled, including user-defined secondary electron emission, sputtering, and surface charging.
• "We don't understand the nature of this cold-electron emission,"
• In electronic equipment, thorium coating of tungsten wire improves the electron emission of heated cathodes.
• Another mechanism to generate free electrons from a cold metallic surface is field electron emission.
• In electron emission mode, the ambient plasma is positively biased with respect to the keeper.
• An example is, which can decay either by positron emission to, or by electron emission to.
• These plots include : orbital motion limited theory, photoemission, secondary electron emission, and secondary ion emission.
• In some respects, field electron emission is a paradigm example of what physicists mean by tunneling.
• Such atoms also typically exhibit Auger electron emission.
• F D statistics was applied in 1926 by Nordheim applied it to field electron emission from metals.
• Wu's experiment compared the distribution of gamma and electron emissions with the nuclear spins in opposite orientations.
