The authors characterized the photoemission behavior of nanostructured surfaces (specifically Ru and Pt nanorod arrays) and observed an ∼15-fold enhancement in photocurrent for a slanted Ru nanorod array (nanorods tilted at ∼40° to the substrate normal) compared to a planar Ru film. The authors show that the improved performance originates from two basic reasons: (1) increased surface area of the nanorods which enhances the photon-collection probability and (2) single crystal nature of the nanorods which increases electron escape probability due to the absence of grain boundaries. Such nanostructured surfaces show promise in a variety of device applications such as photodetectors, photon counters, and photomultiplier tubes.
