The flexible phototransistor could be incorporated into a wide range of applications. They claim that this phototransistor is the fastest and most flexible one ever produced. Tuning the exciton-plasmon coupling for new generation opto-electronic devices.Researchers at the University of Wisconsin-Madison (UW-Madison) have developed a flexible phototransistor based on single-crystalline silicon nanomembranes (Si NM). 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.
