Phototransistors are extensively obtainable with low cost from the distributors of electronic components to use in different electronic circuits. After that, it was used in different applications, and day by day its development was continued. After two years, a phototransistor was demonstrated. The first idea was proposed by William Shockley in the year 1951, after the discovery of a normal bipolar transistor. Tuning the exciton-plasmon coupling for new generation opto-electronic devices.The phototransistor concept was known for the past many years. Our work demonstrates a strategy towards obtaining anĮnvironment-friendly, scalable, high-performance broadband phototransistor by Mediated strong exciton-plasmon coupling, corroborated by COMSOL Multiphysics TheĮnhanced optical properties of the hybrid device are explained via dipole Stability by preventing the degradation of WS$_2$-Ag hybrid system. The additional PVP capping of Ag NPs helps to suppress theĭirect charge and heat transfer and most importantly, increases the device Noise) and high specific detectivity ~1010 Jones in the wide (325-730 nm) Low noise equivalent power (NEP) (~10$^$, considering 1/f Than 5 times higher than the bare graphene/WS$_2$ hybrid device, along with a The fabricated device exhibitsĮxtremely high photoresponsivity (up to $3.2 imes 10^4$ A/W) which is more

In a three-terminal device configuration. Hybrid phototransistor based on monolayer graphene decorated by WS$_2$-Ag NPs Lithography-free fabrication of a large area broadband superior gate-tunable By synthesizing Ag nanoparticles (Ag NPs) capped withĪ thin layer of polyvinylpyrrolidone (PVP) through chemical route, we report a Spontaneous emission in a coupled TMDC and metallic nanostructures, theįabrication of tunable broadband phototransistor with high quantum yield is Strong exciton-plasmon coupling has been demonstrated to improve absorbance and While light-matter interaction mediated by However, the low light absorption due to their small absorption cross section, Has emerged as a viable route towards realizing novel optoelectronic devices.
