SnS2 and SnS Heterostructure Based High Responsivity Broadband Photodetector
This study reports the fabrication, and performance evaluation of an innovative Al/PEDOT: PSS/SnS/SnS2/FTO/Glass photodetector. Utilizing a layered architecture, the device incorporates Al as an electrode, PEDOT: PSS as a hole transport layer (HTL), SnS and SnS2 as the active layer, fabricated on FTO coated glass substrate. The photodetector demonstrates high external quantum efficiency across a broad spectral range of UV, visible and near-infrared (NIR) regions. The proposed device displays a high External Quantum Efficiency EQE (%)/Responsivity Rs(A/W) of $1.98 \times 10~^{4}$ %/56.14, $7.61 \times 10~^{4}$ %/307.15, $7.74 \times 10~^{3}$ % / 71.70 at 350 nm (UV), 500 nm (Visible) and 1150 nm (NIR) respectively, at −1Vbias.
期刊介绍:
IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
