Palladium Diselenide Long-Wavelength Infrared Photodetector with High Sensitivity and Stability
Open accessAbstract
A long-wavelength infrared photodetector based on two-dimensional materials working at room temperature would have wide applications in many aspects in remote sensing, thermal imaging, biomedical optics, and medical imaging. However, sub-bandgap light detection in graphene and black phosphorus has been a long-standing scientific challenge because of their low photoresponsivity, instability in the air, and high dark current. In this study, we report a highly sensitive, air-stable, and operable long-wavelength infrared photodetector at room temperature based on PdSe 2 phototransistors and their heterostructure. A high photoresponsivity of ∼42.1 AW –1 (at 10.6 μm) was demonstrated, which is an order of magnitude higher than the current record of platinum diselenide. Moreover, the dark current and noise power density were suppressed effectively by fabricating a van der Waals heterostructure. This work fundamentally contributes to establishing long-wavelength infrared detection by PdSe 2 at the forefront of long-IR two-dimensional-materials-based photonics.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
