Title:
METHOD OF MANUFACTURING CNT FIELD EMISSION ELEMENT
Document Type and Number:
Japanese Patent JP2005322646
Kind Code:
A
Abstract:
To provide a method of manufacturing CNT (Carbon Nano Tube) emitter capable of reducing thermal shock to an element in high temperature process.
Pulverized CNT is adhered to a first substrate, a metal is vapor-deposited on the surface of the CNT and this is pressure contacted to a surface of a negative electrode. After pressure contacting, the first substrate is isolated from a second substrate to primary stretching the CNT, thereby arranging the CNT perpendicular to the substrate. The CNT emitter perpendicular to the substrate is manufactured without using CVD by this method. The manufactured CNT emitter has excellent electrical characteristics and very high purity.
