Field emission from metal-particle bound with a photoresist

Proposes a film composed of metal particles for use in field electron emitter material on a large substrate. Test films were prepared on a silicon substrate from a mixture of palladium fine particles and positive tone photoresist. It was found that the photoresist at the surface acted as a barrier for electron emission. It was also found that the emission current abruptly increases with time evolution applying a constant voltage. After this phenomenon, the threshold voltage for electron emission was drastically decreased and the emission current became stable.
