Polaronic and Electrochemical Signatures in Group IVB (Ti, Zr, Hf) Oxides: Unified SKP–DFT Insights for Tunable Transport in Energy and Electronic Devices

Advanced Functional Materials, Volume 36, Issue 1, 2 January 2026.
Charge carrier concentration and mobility in TiO2, ZrO2, and HfO2 powder films are experimentally mapped as a function of temperature. The results uncover polaron‐mediated transport regimes and field‐activated conduction, enabling the design of oxide‐based electronic and energy devices with thermally tunable functionality.

Investigating Experimental Short Term Imprint Dynamics in Ferroelectric Hafnium Oxide Through Phase‐Field Modeling

Advanced Functional Materials, Volume 36, Issue 6, 19 January 2026.
Phase‐field modeling reveals the mechanisms behind short‐term ferroelectric imprint in Hf0.5Zr0.5O2 polycrystalline thin films. Combined with a charge trapping model, the proposed framework accurately reproduces coercive field shifts with pause time and their recovery through field cycling in polarization‐voltage measurements, offering valuable ...

Near‐Sensor Analog Computing via Monolithic 3D Piezoelectric Sensor–FeFET for Tactile Sensing System

Advanced Functional Materials, Volume 36, Issue 7, 22 January 2026.
A monolithic 3D‐integrated tactile system combines a piezoelectric sensor and ferroelectric field‐effect transistor (FeFET) to process both static and dynamic pressure signals directly at the sensor node. The system enables in‐sensor analog noise filtering with multi‐level memory states, achieving high sensitivity and ultra‐low power operation (≈10 nW),

Revisiting Ferroelectric‐Gated Phototransistors: A Tripartite Synapse‐Inspired Approach to In‐Sensor Image Processing

Advanced Materials, Volume 38, Issue 1, 2 January 2026.
A ferroelectric‐gated phototransistor (FGPT) enables linear and multilevel modulation of photoconductance through partial polarization switching and photogating effects. The device achieves photonic non‐volatility over a 153 dB dynamic range and performs in‐sensor processing under unstructured illumination, demonstrating enhanced face recognition ...
