ELECTRON EMISSION ELEMENT, METHOD FOR FABRICATING THE SAME, PHOTOELECTRIC CONVERSION ELEMENT EMPLOYING ELECTRON EMISSION ELEMENT, IMAGING APPARATUS AND FLAT PANEL DISPLAY

WIPO Patent Application WO/2007/119524

A1

An electron emission element comprising a lower electrode (2), an upper electrode (7), an electron supply layer (4) arranged on the lower electrode (2) side and an insulator layer (6) arranged on the upper electrode (7) side, the both layers being laminated between the lower electrode (2) and the upper electrode (7), and an electron emitting section including an opening region (HP) defined by an edge portion touching the electron supply layer (4) on the inner wall penetrating the insulator layer (6). The electron emitting section includes a carbon area (8) containing carbon, connected to the upper electrode (7) side and touching the electron supply layer (4) in the opening region (HP), and a partially crystallized polycrystalline portion (41) at that part of the electron supply layer (4) touching the carbon area (8). Area of the lower electrode (2) is set to be not smaller than four times that of the opening region (HP), and the lower electrode (2) overlaps the polycrystalline portion (41) so as to include it through the electron supply layer (4).
