QUANTUM SIZE EFFECT MICRO ELECTRON GUN AND PLANE DISPLAY DEVICE USING THE SAME, PRODUCTION METHOD OF PLANE DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide a quantum size effect micro electron gun capable of easily drawing electrons from a semiconductor by which can be arranged at every pixels, and to provide a thin image display device having high quantum efficiency, high brightness by utilizing the electron gun, as well as its production.;SOLUTION: Conductive electrons in a n-type semiconductor substrate 2 are accelerated in a layer 4 of quantum size effect particulates 3 laminated on the surface of the n-type semiconductor substrate 2 by an electric field, without being subjected to phonon scattering. When arriving an electrode 5, they can be released into a vacuum with greater energy than the working function of the electrode 5. The quantum size effect particulates 3 have the surfaces provided with nano-order semiconductor microcrystals having sufficiently discrete energy level of electrons to cause no phonon scattering and insulators having thicknesses enough to permit the tunneling of the electrons.;COPYRIGHT: (C)2001,JPO
