| 发明名称 | Method for making field emission cathode | ||
| 摘要 | The disclosure relates to a method for making field emission cathode. A microchannel plate is provided. The microchannel plate includes a first surface and a second surface opposite to the first surface. The microchannel plate defines a number of holes extending through the microchannel plate from the first surface to the second surface. The plurality of holes are filled with a carbon nanotube slurry. The carbon nanotube slurry is adhered on inner walls of the plurality of holes. The carbon nanotube slurry in the plurality of holes is solidified. | ||

| 主权项 | 1. A method for making field emission cathode, the method comprising: providing a first microchannel plate, wherein the first microchannel plate comprises a first surface and a second surface, opposite to the first surface; the first microchannel plate defines a plurality of first holes extending through the first microchannel plate from the first surface to the second surface; a diameter of each of the plurality of first holes is in a range from about 10 micrometers to about 40 micrometers; and a distance between adjacent first holes is in a range from about 2 micrometers to about 10 micrometers; filling the plurality of first holes with a carbon nanotube slurry, wherein the carbon nanotube slurry is adhered on inner walls of the plurality of first holes; and solidifying the carbon nanotube slurry. | ||
