Material‐Driven Neuronal Oscillators and Filters via Active Reactance in CC‐NDR and VC‐NDR Electro‐Thermal Memristors

Advanced Physics Research, Volume 5, Issue 7, July 2026.
Active reactance in electro‐thermal memristors emerges intrinsically from rapid thermal switching of device resistance, linking current‐controlled and voltage‐controlled negative differential resistance to neuronal spiking dynamics. Opposing temperature coefficients of resistance give rise to active inductive or capacitive responses, enabling tunable ...

Electrically Tunable Room‐Temperature Microwave Oscillations in GaN/AlN Triple‐Barrier Resonant Tunneling Diodes

Advanced Electronic Materials, Volume 12, Issue 9, 11 May 2026.
III‐nitride semiconductors have revolutionized optoelectronics, enabling transformative technologies such as high‐efficiency LEDs and lasers. However, their use in intersubband optoelectronics has remained limited. This work marks an important step forward by demonstrating highly coherent inter‐well resonant tunneling injection in III‐nitride ...

High-power oscillations exceeding 1 mW using a single resonant-tunneling diode oscillator in the 0.6–0.7 THz range

Applied Physics Express
Conventional resonant-tunneling-diode (RTD) terahertz (THz) oscillators with rectangular cavity resonators typically exhibit low output power due to resistive losses in the resonator and surrounding RTD structure.

Design and Simulation of III‐Nitride‐Based Polarization‐Matched Resonant‐Tunneling Diodes with Quaternary AlGaInN Quantum Wells and Ternary AlInN Double Barriers

physica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 12, December 2025.
This article proposes novel III‐nitride‐based resonant‐tunneling diodes (RTDs) with polarization‐matched (PM) nano‐heterostructures consisting of quaternary AlGaInN quantum wells and ternary AlInN double barriers. The simulation results exhibit that the PM‐RTD structures effectively suppress the formation of polarization‐induced built‐in electric ...

A 3D Printing Strategy for Hard Curved Surfaced Circuits: From Materials to Applications

Advanced Science, Volume 12, Issue 36, September 25, 2025.
Conventional PCB etching (multi‐step) and indirect transfer techniques fail to meet structural electronics’ demands for lightweight, miniaturized, and customized manufacturing. 3D‐printed conformal circuits enable direct integration of conductive traces into substrates or onto surfaces, achieving integrated structural‐functional fabrication.
