58.1: Invited Paper: Highly Efficient and Long Life MIM Cathodes for FEDs

The lifetime of MIM cathodes was lengthened to more than 20,000 hours by using a thinner tunneling insulator (6.9 nm), while the emission efficiency was enhanced to more than 3% by mixing CsHCO3 into a Au/Pt/Ir top electrode. The mechanism of long life and high efficiency will be discussed.
