Low‐Field Giant Dielectric Tunability by Polaron‐Mediated Interfacial Polarization in Pulsed‐Laser‐Deposited‐Nanocrystalline/Amorphous Composite BaTiO3 Thin Films

open access: yesAdvanced Electronic Materials, EarlyView.
Comparison of tunability efficiency between vacuum‐deposited PLD‐BTO films grown at Td = 550°C in the present study and representative previous reports. ABSTRACT Electrically tunable dielectric thin films are essential components for next‐generation low‐voltage electronic devices.

Drift Reduction in 2D PtSe2 Piezoresistive Pressure Sensors Through an On‐Chip Wheatstone Bridge

open access: yesAdvanced Electronic Materials, EarlyView.
Drift is a major source of error affecting the accuracy and repeatability of sensors. A Wheatstone bridge (WSB) enables high sensitivity, accuracy, and the elimination of common‐mode drift. We apply the WSB concept to highly sensitive piezoresistive pressure sensors made with two‐dimensional layered platinum diselenide transducers.

Decoupled Dielectric Optimization and YbOx Contact Engineering in All‐Spray‐Processed Oxide Thin‐Film Transistors

open access: yesAdvanced Electronic Materials, EarlyView.
Fully spray‐processed oxide thin‐film transistors are advanced by decoupling dielectric quality from contact energetics. Thermochemically densified MgO suppresses defect‐mediated leakage and improves electrostatic control, while an ultrathin YbOx interlayer induces a 1.67 eV work‐function shift that boosts mobility from ∼40 to ∼94 cm2 V−1 s−1.

Broadband Near‐Field Computational Microwave Imaging Enabled by Nonperiodic Dispersive Unit‐Cell Loading in a Passive Metasurface

open access: yesAdvanced Electronic Materials, EarlyView.
A compact passive engineered surface converts changes in microwave frequency into many distinct illumination patterns, allowing nearby objects to be imaged without mechanical scanning, active tuning, or a large antenna array. Operating from 18 to 28 GHz, the single‐port system uses measured field patterns to reconstruct metallic targets and distinguish
