Abstract

In this work we investigate the use of Au nanorods as optically actuated electron emitter arrays. We have fabricated high-density arrays of 10 nm diameter Au nanorods via electron beam lithography and studied the effects of, emitter array density on charge yield, and laser intensity on emitter morphology, respectively. Additionally, we have numerically simulated the magnitude of the local electric field at the surface of emitter arrays with various layouts and geometries. This investigation thus provides us with a better understanding of optically actuated electron emission phenomena within high-density electron emitter arrays.
