What is Bismuth-Doped Ag2Te Quantum Dots for SWIR about?

This study presents bismuth-doped Ag2Te colloidal quantum dots (Bi:Ag2Te QDs) as a solution to the high defect density problem in silver telluride QDs, which adversely affects their performance in shortwave-infrared (SWIR) photodetectors. The Bi doping improves the optoelectronic properties, resulting in photodiodes with external quantum efficiencies of 30% and specific detectivity of 7.67 × 10^10 Jones at 1460 nm. This research not only introduces high-performance QDs for SWIR applications but also highlig
