Short-wave infrared photodetector
Splet10. apr. 2024 · Here, we demonstrate a mixed-dimensional WS2/WSe2/p-Si unipolar barrier photodetector, in which 2D WS2 acts as the photon absorber, atomically thin WSe2 as the unipolar barrier, and 3D p-Si as the photogenerated carrier collector. ... Recent progress in short- to long-wave infrared photodetection using 2D materials and heterostructures. … Splet29. sep. 2024 · We demonstrate simple proof-of-concept broad spectrum photodetectors with responsivities above 0.1 AW-1 across both the visible and short-wave infrared wavelengths. This corresponds to a specific detectivity of ∼10 9 cm Hz 1/2 W -1 at λ = 1.4 μm at room temperature.
