Abstract

Palladium atoms have been deposited onto graphene where they catalyse etching processes in conjunction with the e-beam, during/after which they reside at the edges of the holes, which have formed in the graphene. Energy filtered imaging reveals that the low loss feature at 2-4 eV constituting the shoulder of the graphene n-plasmon, is up to 10 times enhanced at Pd-decorated graphene edges compared to clean monolayer graphene, rendering it a useful feature for electric field enhancement applications in the optical regime
