Abstract:
An electron beam apparatus comprising an electron-emitting device, an anode electrode, a first voltage applier, arranged to apply a voltage Vf(V) to said electron-emitting device and a second voltage applier, arranged to apply another voltage Va(V) to said anode,wherein said electron-emitting device has an electron emitting region arranged between a lower potential side electrode and a higher potential side electrode, and has an electron-scattering plane forming layer arranged from said electron-emitting region to said higher potential side electrode on a surface of said electron-emitting device, and said electron-scattering plane forming layer elastically scatters electrons at a boundary between said surface of said electron emitting device and said electron-scattering plane forming layer, thereby making greater an emitting-current as compared with that which would be obtained without said electron scattering plane forming layer.
