Position-Dependent MXene Interface Engineering Enables Efficient Charge Extraction for High-Performance Ag2Te Colloidal Quantum Dot Infrared Photodetectors.
Silver telluride (Ag2Te) colloidal quantum dots (CQDs) are promising infrared (IR) absorbers without heavy metals due to their adjustable bandgap, environmental friendliness, and solution processability, yet photodetector performance is frequently hindered by inferior charge transport, interfacial recombination, and su...
