Title:
【発明の名称】誘電集束層を有するフィールド・エミッション・デバイス
Document Type and Number:
Japanese Patent JP2002536802
Kind Code:
A
Abstract:
A field emission device (110, 210, 310, 410) includes an electron emitter (124), a first dielectric focusing layer (122) defining a first aperture (127), and a second dielectric focusing layer (123) defining a second aperture (133). Second dielectric focusing layer (123) is disposed on first dielectric focusing layer (122). The dielectric constant of second dielectric focusing layer (123) is less than the dielectric constant of first dielectric focusing layer (122). During the operation of field emission device (110, 210, 310), electron emitter (124) emits an electron beam (134), which is focused as it travels through first aperture (127) and then through second aperture (133).
