Abstract
An electron emitting device includes at least a first electrode and an electron emitting section provided on the first electrode. The electron emitting section is formed of a particle or an aggregate of particles. The particle contains a carbon material having a carbon six-membered ring structure. The carbon material having a carbon six-membered ring structure contains, for example, graphite or a carbon nanotube as a main component.
Claims41
An electron emitting device, comprising at least a first electrode and an electron emitting section provided on the first electrode, wherein:
- the electron emitting section is formed of a particle or an aggregate of particles, and
- the particle contains a carbon material having a carbon six-membered ring structure, the structure having a portion at which a σ bond of carbon six-membered rings is broken.
An electron emitting device, comprising at least a first electrode and an electron emitting section provided on the first electrode, wherein:
- the electron emitting section is formed of a particle or an aggregate of particles,
- the electron emitting section is fixed on the first electrode with a fixing material, and
- the particle contains a carbon material having a carbon six-membered ring structure, the structure having a portion at which a σ bond of carbon six-membered rings is broken.
A method for producing an electron emitting device, comprising at least the steps of:
- forming a first electrode;
- and
- providing an electron emitting section formed of a particle or an aggregate of particles on the first electrode,
- wherein a particle formed of a material containing a carbon material having a carbon six-membered ring structure, the structure having a portion at which a σ bond of carbon six-membered rings is broken, is used as the particle.
A method for producing an electron emitting device, comprising at least the steps of:
- forming a first electrode;
- and
- providing an electron emitting section formed of a particle or an aggregate of particles on the first electrode,
- wherein the step of providing the electron emitting section on the first electrode includes:
- an application step of applying a solution obtained by mixing a fixing material and the particle forming the electron emitting section onto a surface of the first electrode, and
- a drying step of drying the solution so as to remove the fixing material at least from a part of a surface of the electron emitting section, the part being in the vicinity of an electron emitting site and including the electron emitting site.
