Key Points

Surface ligand engineering significantly improves the detectivity of Ag2Te colloidal quantum dots for SWIR applications.
Ag2Te CQDs showed enhanced performance metrics compared to traditional mercury and lead-based CQDs.
The study employs ligand engineering techniques to optimize the electronic properties of quantum dots, facilitating better photodetector performance.
These findings highlight the potential for Ag2Te CQDs to surpass limitations of traditional photodetectors.

Implication

Engineering of surface ligands enhances detectivity in Ag2Te colloidal quantum dots, suggesting improvements over traditional technologies.

Abstract

Traditional colloidal quantum dots (CQDs) used for shortwave infrared (SWIR) photodetectors, such as mercury (Hg)-based and lead (Pb)-based CQDs, have been developed with high detectivity and fast responses, but they...
