Enhanced quantum efficiency of photoelectron emission, through surface textured metal electrodes
Abstract
Here, it is predicted that the quantum efficiency (QE) of photoelectron emission from metals may be enhanced, possibly by an order of magnitude, through optimized surface texture. Through extensive computational simulations, it is shown that the absorption enhancement in select surface groove geometries may be a dominant contributor to enhanced QE and corresponds to localized Fabry–Perot resonances. Finally, the inadequacy of extant analytical models in predicting the QE increase, and suggestions for further improvement, are discussed.
