Title:
QUANTUM SIZE EFFECT TYPE MICRO ELECTRON GUN AND FLAT DISPLAY UNIT USING IT AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO/2001/091155
Kind Code:
A1
Abstract:
A quantum size effect type micro electron gun provided for each pixel in which electrons are derived easily from a semiconductor utilizing a quantum size effect, a thin image display unit having high quantum efficiency and luminance utilizing that electron gun, and a method for manufacturing the same. Conduction electrons of an n-type semiconductor substrate (2) are accelerated by a field without subjected to phonon scattering in the layer (4) of quantum size effect fine particles (3) formed on the surface of the n-type semiconductor substrate (2) to have energy higher than the work function of an electrode (5) when arriving at an electrode (5) before being emitted into vacuum. The quantum size effect fine particle (3) is provided, on the surface thereof, with semiconductor microcrystals of nano order having an energy level of electrons dispersed to such an extent as causing no phonon scattering, and an insulator thin enough to permit tunneling of electrons.
