Title:
ELECTRON DISCHARGING DEVICE
Document Type and Number:
Japanese Patent JP3580930
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide an electron discharging device capable of discharging electrons effectively from its surface and operating long.
SOLUTION: The device includes metallic body 1, semiconductor 2 having negative electron affinity, such as diamond, A1N, or BN joined to the metallic body/and an electrode 4 electrically isolated from the metallic body 1 and the semiconductor 2. The electrode 4 is also disposed apart from the semiconductor 2. By taking the semiconductor 2 as a thin layer of about 10nm or less in thickness and terminating its surface with hydrogen atoms, excellent electron discharging performance can be obtained.
