Nucleophilic Covalent Ligands Enable Simultaneous Surface Reconstruction and Passivation of Colloidal InSb Quantum Dots for Stable Short‐Wave Infrared Photodetectors

Angewandte Chemie, EarlyView.
A simultaneous surface reconstruction and passivation strategy is designed for indium antimonide (InSb) colloidal quantum dots (CQDs) using sulfur‐based nucleophilic covalent ligands. This leads to stable CQD inks and 1450 nm‐operating InSb CQD photodetectors with 28% external quantum efficiency and 300 h operating lifetime. Abstract Indium antimonide (

Overcoming Endurance Limitations in Organic Nonvolatile Memories Through N‐Type Small‐Molecule Semiconductor Implementation and Thermal Optimization

Advanced Electronic Materials, EarlyView.
The defects in the charge‐trapping layer are believed to be responsible for endurance degradation in organic transistor nonvolatile memory (ONVM). The ONVM employing thermally treated n‐type semiconductor as the charge‐storage layer can maintain prolonged stable endurance for up to 104 cycles through annealing the charge‐trapping layer, paving the way ...
