Low voltage diamond field emitter and method of manufacturing the same, field emission device, flat panel field emission display

摘要

Applicants have discovered a way to manufacture, process and use diamonds that greatly improves the ability of low voltage emissions.;Specifically, the Applicant has found that defect-rich diamonds (diamonds grown or treated to increase the concentration of defects) improve the toxicity of undervoltage releases. Defective diamonds are 5-15 cm^-One(Preferably 7-11 cm^-One(Ful1 width at half maximum) within the range of 1332 cm^-OneIs characterized in Ramanspectroscopy for its diamond peak. Such defective diamonds can emit electron current densities of 0.1 mA / mm 2 or more at a low applied electric field of 25 V / m or less. Particularly beneficial structures use such almonds in arrays of islands or particles with diameters less than 10 m each at an electric field of 15 V / m or less.
