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

Advanced 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 ...

Prompt Engineering Accelerates the Data‐Driven Discovery of Photocatalysts via an LLM‐Based Model Ensemble Strategy

Advanced Science, EarlyView.
This work establishes a pipeline that transforms fragmented literature into a structured database for graphitic carbon nitride photocatalyst discovery. A prompt‐engineered, cross‐model large language model ensemble automates high‐fidelity extraction, enabling interpretable machine learning to identify dominant performance descriptors. These data‐driven

Charge Injection and Transport in an Isoindigo‐Based Polymer Transistor

Advanced Electronic Materials, EarlyView.
This study presents the charge injection and transport properties of field‐effect transistors based on an isoindigo‐bithiophene donor‐acceptor polymer semiconductor contacted with thiolated self‐assembled monolayer (SAM)‐functionalized electrodes. Temperature‐dependent contact characteristics are measured and simulated.

Non‐Uniform Space‐Time‐Coding Modulation for Low‐Complexity Diagnostics of Reconfigurable Intelligent Surfaces

Advanced Electronic Materials, EarlyView.
A diagnostic method for reconfigurable intelligent surfaces (RIS) based on non‐uniform space‐time‐coding modulation is presented. Fault localization is achieved via amplitude‐only spectral measurements, eliminating the need for complex signal processing. A one‐to‐one mapping between harmonic components and RIS elements enables accurate detection.
