Interfacial Synergy in a Band‐Aligned Low‐Dimensional Heterojunction Toward Broadband Photodetection

open access: yesAdvanced Science, EarlyView.
Monolithically integrating sensing and communication, a Ta2NiSe5/Sb2Te3 heterojunction achieves visible‐to‐near‐infrared photovoltaics with high‐speed terahertz photo‐thermoelectric detection at room temperature. By engineering a Type‐II van der Waals heterojunction, we overcome the intrinsic spectral limitations and disparate physical requirements of ...

Absorption‐Dominant Electromagnetic Interference Shielding of Ti3C2Tx MXene‐Coated and Fe3O4‐Integrated TPMS Composites with Coupled Gradient Conductivity and Size‐Graded Structure

open access: yesAdvanced Science, EarlyView.
A functionally driven variable‐cell size and gradient‐conductive coated TPMS structure was developed. Accordingly, stepwise longitudinal gradient impedance was realized, achieving absorption‐dominant EMI shielding (absorptivity≈0.85) with an EMI SET of ≈ 59 dB, for 10 mm‐thick composites. Further increasing the thickness of composites to 20 mm achieved

Threshold‐Voltage Modulation and N2O Plasma Passivation for Enhanced Retention and Memory Window in Capacitorless 2T0C DRAM Oxide Thin‐Film Transistors

open access: yesAdvanced Science, EarlyView.
Al:ITZO‐based capacitorless 2T0C DRAMs are realized by combining N2O plasma‐induced defect modulation with read‐transistor W/L optimization to suppress leakage and stabilize data storage. This device‐level engineering enables zero‐bias hold operation, retention times exceeding 1000 s, and a 13‐fold expansion of the memory window, demonstrating a ...
