| titleOfInvention | A kind of heat helps Field Electron Emission cathode construction and preparation method thereof |
| abstract | The invention discloses a kind of heat to help Field Electron Emission cathode construction and preparation method thereof；Cathode construction is made of perpendicular to substrate surface top pointed cone and bottom nano-channel；The cone angle of pointed cone is 15 °~60 °, and the diameter or width of nano-channel narrowest part is 10~100 nm；When cathode construction works, the conduction for the Joule heat that pointed cone produces in nano-channel limiting field emission process, raises pointed cone temperature, realizes that heat helps Flied emission, lifts electron emission capability；Negative-feedback metering function possessed by nano-channel resistance, can avoid emitter overcurrent from puncturing；Thermal capacitance possessed by pointed cone can avoid the excessive fusing of own temperature.Cathode construction of the present invention had not only realized " self-heating " of emitter, but also high temperature and high current can be avoided to cause cathode degradation, was conducive to application of the cathode on low-voltage driving, high stability electronic source.The cathode construction is without heat filament, simple in structure, the making in array electronic source easy to implement. |
