The field emission which was reinforced from the carbon nano tube which is mixed with the grain

摘要

This invention cathode (100) with, the carbon nano tube (CNT) (105) and the grain (104) the cathode material which is included (106) with makes purpose. In addition as for this invention, the cathode of this invention (100) the field emission device, and these cathodes which are included (100) also the manner which produces makes purpose. With several execution features, the cathode of this invention (100) field emission display (200) it is used in. In addition as for this invention, the substrate (204) CNT (105) with the grain (104) with making formation accumulate on, the cathode of this invention (100) the manner which is produced, and as a result CNT which is used in this mixed layer the fact that field emission property of the formation which is obtained is optimized in field emission display application as a purpose, (105) the manner which controls density is included.
