This work overcomes long‐standing crucial technical difficulties in miniaturizing micro‐wave detectors, caused by the longer‐wavelength diffraction limit, with carbon nanotube (CNT) film photo‐thermoelectric sensors. The CNT film sensor exhibits sensitive micro‐wave detection operations with signal‐to‐noise ratios over 1400 at compact device sizes ...

Ultra‐low LOD H2O2 Sensor Based on Synergistic Nernst Potential Effect
Due to the synergistic effect of ENernst,H2O2${E}_{\mathrm{Nernst},\ {\mathrm{H}}_{2}{\mathrm{O}}_{2}}$ and ENernst,H+${E}_{\mathrm{Nernst},\ {\mathrm{H}}^{+}}$, the proposed sensors in this study can achieve ultralow H2O2 detection limit as low as 1.8 × 10−12 M based on the stacked PEDOT: BTB/PEDOT: PSS semiconducting layer.

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 (

An optimal dynamic balance between carrier lifetime and transit time is achieved in the Bi2O2Se/Ta2NiSe5 tunneling heterojunction, which simultaneously attains high responsivity (>103 A W−1) and a fast response time (≈5 µs). The specific detectivity can reach 3.75 × 1013 Jones at 633 nm and 1.8 × 1010 Jones at 1550 nm. Abstract New technologies such as
