Implications of Transient Negative Capacitance Effect in Ferroelectric Polarization Dynamics

Advanced Electronic Materials, EarlyView.
Transient voltage artifacts observed during ferroelectric switching are shown to originate from measurement circuitry rather than intrinsic negative capacitance. By correlating switching current, time scale, and series resistance, this work establishes practical design rules for reliable pulse‐switching experiments and circuit integration of ...

Ultra‐Low Power Consumption and Highly Durability in Sm:HfO2 Thin Film Ferroelectric Memristor for Edge Detection

Advanced Electronic Materials, EarlyView.
ABSTRACT With the continuous development of computer image processing, developing efficient and low‐power computing devices has become a key challenge. Memristors have integrated in‐situ storage and computing capabilities, making them an ideal choice for low‐power image processing computing architectures. However, current memristors are confronted with

Wafer‐Scale Bi2O2Se‐on‐Insulator Thin Films for Integrated Electronics

Advanced Electronic Materials, EarlyView.
Wafer‐scale, thickness‐controlled semiconducting Bi2O2Se thin films were grown on 2‐inch insulating sapphire substrates via magnetron sputtering using quasi‐van der Waals epitaxy. The uniform films enable large‐scale fabrication of top‐gated TFT arrays with stable enhancement‐mode operation and functional inverter, NAND, and NOR logic gates.
