Lateral Profile of Doping Concentration Extracted From the C‐V Characteristics in Self‐Aligned Top‐Gate Coplanar InGaZnO Thin‐Film Transistors

open access: yesAdvanced Electronic Materials, EarlyView.
For self‐aligned top‐gate amorphous InGaZnO thin‐film transistors (TFTs), a capacitance‐voltage‐based extraction technique that directly reconstructs a lateral doping profile and key parameters is proposed. The extracted profiles are validated by direct comparison with the transfer‐length method.

Research Progress and Applications of Non‐Carrier‐Injection Electroluminescence

open access: yesAdvanced Electronic Materials, EarlyView.
Non‐carrier‐injection electroluminescence (NCI‐EL) uses AC fields and displacement currents to trigger light from internal charge reservoirs, enabling minimalist emitters with remotely coupled terminals. This review maps shared mechanisms across organics, GaN, quantum dots, and TMDCs, compares planar, interdigital, single‐terminal, and coaxial designs,

Unity power factor converter [PDF]

open access: yes, 1980
A unity power factor converter capable of effecting either inversion (dc-to-dc) or rectification (ac-to-dc), and capable of providing bilateral power control from a DC source (or load) through an AC transmission line to a DC load (or source) for power ...

Acoustic Impedance‐Tailored High‐Performance Ultrasound‐Driven Triboelectric Nanogenerators

open access: yesAdvanced Energy Materials, EarlyView.
An acoustic impedance–mismatched triboelectric nanogenerator is presented for efficient ultrasound energy harvesting in implantable medical devices. Concave and convex membrane patterning induces controlled acoustic impedance mismatch, which boosts output by ∼200% and ensures stable operation over 100 million cycles and six weeks in vivo, highlighting ...

Oxygen‐Driven Structural Reorganization by Trace Water Enabling Fast Li‐Ion Transport in a Pliable Solid Electrolyte

open access: yesAdvanced Energy Materials, EarlyView.
Trace water is acting as a constructive mediator in 2LiCl–GaF3, markedly increasing ionic conductivity while reorganizing local coordination. Hydration creates localized Li+ solvation environments and partially dissociates ion pairs, enhancing Li‐ion mobility.
