    Abstract: This disclosure relates to a dielectric layer response-based field effect transistor photodetector, comprising a gate, a photoelectric response composite dielectric layer, a carrier transport layer, a source, and a drain. The composite dielectric layer is formed by compounding a photoelectric response dielectric and a charge blocking insulating dielectric; the carrier transport layer is used for transporting electrons or holes, the photoelectric response dielectric is used for absorbing light under illumination to generate electrons, holes or excitons, and the charge blocking insulating dielectric is used for limiting passage of the electrons, holes or excitons. The generation of photogenerated electrons, holes or excitons in the composite dielectric layer and the movement of the photogenerated electrons, holes or excitons limited within the photoelectric response dielectric cause the equivalent permittivity of the composite dielectric layer to change, causing changes in carrier concentration and conductivity of the carrier transport layer and achieving photoelectric detection.
