Enhancing Light-Matter Interactions In Mos2 By Copper Intercalation

Tech ID: 33397 / UC Case 2021-891-0

Abstract

Researchers at the University of California, Davis have developed layered 2D MoS2 nanostructures that have their light-interactive properties improved by intercalation with transition and post-transition metal atoms, specifically Copper and Tin.

Full Description

The technology involves photodetectors made of 2-dimensional vertically-aligned MoS2 layers. The van der Waals gap in at least two layers of MoS2 is intercalated with metal atoms such as Copper and Tin to enhance light-matter interactions. These intercalated atoms introduce electronic states near the MoS2’s conduction band, boosting the photodetector's efficiency, especially in the near-infrared spectrum.

Applications

  • Optical sensors such as photodetectors 
  • Night-vision image intensifiers 
  • Technologies operating in low-light conditions or high vegetation terrain.

Features/Benefits

  • Enhanced light-matter interactions in near-infrared spectrum 
  • Improved photodetector efficiency 
  • Increased photoresponsivity and absorption capabilities in the infrared range. 
  • Addresses weak absorption in IR spectral region of 2D MoS2 devices 
  • Solves inefficient light-interactive properties of 2D MoS2 structures.
