Abstract
Embodiments of the present disclosure provide methods of growing halide films (e.g., single crystal halide perovskites or multi-crystal halide perovskites) on a structure, dual-mode photodetectors, methods of use, and the like.
Claims14
A device, comprising:
- a dual-band photodetector having a microcrystalline film deposited on a substrate,
- wherein the microcrystalline film is positioned on a top side of the dual-band photodetector and the substrate is positioned on a bottom side of the dual-band photodetector,
- wherein the microcrystalline film is a halide perovskite,
- wherein the dual-band photodetector is configured to operate as a narrow-band photodetector upon illumination from the top side and the dual-band photodetector is configured to operate as a wide-band photodetector upon illumination from the bottom side.

A method of making a photodetector, comprising:
- providing precursor materials for a microcrystalline film;
- and
- depositing a microcrystalline film on a substrate to form a dual-band photodetector,
- wherein the microcrystalline film is positioned on a top side of the dual-band photodetector and the substrate is positioned on a bottom side of the dual-band photodetector,
- wherein the microcrystalline film is a halide perovskite,
- wherein the dual-band photodetector is configured to operate as a narrow-band photodetector upon illumination from the top side and the dual-band photodetector is configured to operate as a wide-band photodetector upon illumination from the bottom side.
