Abstract
This letter reports a Al/WSe2:MoS2/ITO coated PET structure based broadband photodetector. The device utilizes WSe2: MoS2 nanocomposite (NC) as an active layer prepared using dispersion method. The nanocomposite film was deposited over ITO coated PET through spin coating technique. The Al contacts were deposited over WSe2: MoS2 nanocomposite by means of thermal evaporation unit. The proposed photodetector exhibits a broad photo response with maximum responsivity
$\text {R}_{\text {S}}$
(A/W) of 10.75 A/W, 85.45 A/W, and 146.96 A/W; at 350nm (UV), 750nm (visible) and 900nm (IR) at -1V bias. The nanocomposite shows promising characteristics for optoelectronic application. WSe2:MoS2 NC shows a wide absorbance spectra, covering ultraviolet (UV)-visible-near infrared (NIR) regions.
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.
