Ternary Ag-Te-S colloidal quantum dots for shortwave infrared photodetectors
Ecofriendly silver telluride (Ag2Te) colloidal quantum dots (QDs) are promising for shortwave infrared (SWIR) photodetectors. However, the performances of the devices–especially beyond 1.5 μm–remain constrained photoelectric conversion efficiency due to inefficient charge extraction. Here, we develop a ternary Ag-T...
