Figure 2From: Photocurrent enhancement mechanisms in bilayer nanofilm-based ultraviolet photodetectors made from ZnO and ZnS spherical nanoshellsElectric field (| E |) distribution and absorption power distribution. (a) Electric field (|E|) distribution based on full-wave simulation of electromagnetic waves coupled with the ZnO hollow-sphere nanofilm at 370 nm. (b) Power distribution of the ZnO hollow-sphere nanofilm at 370 nm. (c) Electric field (|E|) distribution based on full-wave simulation of electromagnetic waves coupled with the ZnO hollow-sphere nanofilm at 350 nm. (d) Power distribution of the ZnO hollow-sphere nanofilm at 350 nm.Back to article page
