Abstract
The invention is to provide a producing method for an electron emitting device of field emission type, having sufficient on/off characteristics and capable of efficient electron emission at a low voltage. There is provided a producing method for an electron emitting device including steps of preparing a plurality of electroconductive particles each covered with an insulation material having a thickness of 10 nm or less at least on a part of a surface of the particle, and forming a dipole layer on a surface of the insulation material covering each of the plurality of electroconductive particles.
Claims10
A method for producing an electron-emitting device comprising steps of:
- preparing a plurality of electroconductive particles each covered with an insulation material having a thickness of 10 nm or less at least on a part of a surface of the particles;
- and
- forming a dipole layer on a surface of the insulation material covering each of the plurality of electroconductive particles,
- wherein the step of preparing a plurality of electroconductive particles each covered with an insulation material includes:
- preparing a resin layer;
- making the resin layer absorb a metal which constitutes electroconductive material through an ion exchange;
- and
- converting the resin layer into an insulation material layer containing electroconductive particles, by baking the resin layer for decomposing an organic component in the resin.
