Abstract

With the increasing demand for ultraviolet detectors, improving their photoelectric conversion capacity has become an interesting research topic. A theoretical model for the photoemission of field-assisted AlGaN heterojunction nanorod array photocathodes is established, which is favorable for alleviating the phenomenon of photoelectrons absorbed by adjacent nanorods. Illuminated by oblique incident light and assisted by 0.5 V/µm electric field, a maximum improvement of 42.3% in the electron collection efficiency can be implemented. The model discussed in this article can provide some theoretical references for the design and manufacture of high-efficiency solar-blind ultraviolet detectors.
