Photogating-Enhanced NIR Graphene Photodetector with Integrated Dielectric Metasurface and Plasmonic Layer for Border Surveillance

 

Project no.: S-LU-26-10

Project description:

The goal of this project is to develop a near-infrared graphene photodetector for border monitoring and control. The sensitivity of the device is increased by applying the photogating effect, dielectric metasurfaces for light concentration and plasmonic nanolayer for strengthening the local electric field. The combination of these solutions allows to ensure high sensitivity (responsivity) of the photodetector in low light or detection of the visually masked targets.

Project funding:

Intergovernmental programme administrated by Research Council of Lithuania: Lithuania–Ukraine
