Abstract

We show the reduction of the nonlinear electron emission order of an eCarbon/gold bilayer driven by a surface plasmon wave. The eCarbon layer allows for higher confined electric fields and increased electric field enhancement which increases lower order electron emission compared to an Au film. This bilayer represents a unique platform for the next generation of ultrafast electron sources operating at low laser intensities.
