Abstract:
Based on a traditional thermal cathode，catalyst material layer has been deposited，and then carbon nanotube layer has been synthesized on the surface of the thermal cathode by self-heated chemical vapor deposition． As is known， carbon nanotube has excellent field emission properties，and the field emission capability of this cathode has been tested in a diode structure，a maximum 5. 4mA current has been obtained． We provide a new way to realize field emission large current on a traditional thermal cathode device while the cathode material and the whole structure need not be changed．
