Strong-field photoemission from silicon field emitter arrays is investigated experimentally and results are explained using a simple-man optical-field emission model. Spectra are collected throughout an in-situ laser annealing process, leading to a red-shift in emitted electron energy along with an increase in electron yield. After the annealing process, a high energy plateau is formed which is explained through optical-field emission along with electron re-scattering with the tip surface.
