Abstract
Incorporating plasmonic metal nanostructures with the semiconductor compounds offers a new route to significantly improving the performance of photodetectors. Herein, we developed five hybrid structures to demonstrate ultrasensitive photodetection in in MIR, visible and UV regions, respectively. These five demonstrations are, 1. Plasmonic Metasurface Integrated Black Phosphorus-Based Mid-Infrared Photodetector with High Responsivity and Speed, 2. Ultrasensitive Gateless Photodetector based on 2D Bilayer MoS2-1D Si Nanowire-0D Ag Nanoparticle Hybrid Structure, 3. Enhanced Photoresponsivity of Perovskite QDs/Graphene Hybrid Gate-free Photodetector by Morphologically Controlled Plasmonic Au Nanocrystals, 4.Ultrasensitive Photodetection of Monolayer MoS2 using Semimetal Plasmonic Structure and Ohmic Contact, and 5. A Multifunctional Plasmonic Sensor for Excellent UV Photodetection and NO2 Gas Sensing by an Array of Al Nanocaps on GaN Truncated Nanocones.
