Operando Tracking of Oxygen‐Vacancy Dynamics and Negative Capacitance in Ca‐Doped BiFeO3
Advanced Functional Materials, EarlyView.Operando electrochemical impedance spectroscopy, combined with electrocoloration, enables a direct correlation between real‐space ionic redistribution and the corresponding frequency‐domain electrical response. In lateral Ca‐doped BiFeO3 devices, time‐resolved impedance snapshots capture the evolution from bulk‐dominated mixed conduction to an ...

From Photometric-Motion to Shape from Shading
, 2004 A new approach to shape estimation from shading input has been recently introduced through the processes of disparity-based photometric stereo (DBPS) and Green's function shape from shading (GSFS). Both processes start from a pair of constraints - a

Advanced Functional Materials, EarlyView.This Perspective highlights atom probe tomography as a powerful tool for understanding the atomic‐scale defect chemistry in HfO2‐based ferroelectrics. 3D mapping of dopants, point defects, and interface chemistry can provide new insight into defect‐driven mechanisms underpinning the ferroelectricity in the system and guide the design of more reliable ...

Two Coexisting Pathways to Volatility in Valence‐Change Memory Devices
Advanced Functional Materials, EarlyView.Volatile VCM‐type memristive devices exhibit current relaxation after resistive switching, but their microscopic origin remains debated. Using pulsed measurements and a new Tunnel‐DLTS approach on Pt/SrTiO3/Nb:SrTiO3 devices, we show that post‐SET volatility is predominantly ionic, while electronic contributions—arising from quasi‐Fermi‐level ...

Constructing a Depth Map from Images
, 1983 This paper describes two methods for constructing a depth map from images. Each method has two stages. First, one or more needle maps are determined using a pair of images.

Electrostatic Superlattices Beyond 1:1 Stoichiometry
Advanced Functional Materials, EarlyView.Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl

Advanced Functional Materials, EarlyView.A new class of sulfur‐free, oxygen‐bridged dibenzofuran‐based polymers is developed for ultrahigh‐refractive‐index applications. The rigid π‐extended architecture and enhanced molecular polarizability enable exceptional optical performance, combining refractive indices up to 1.848 with high Abbe numbers and full visible transparency. This work offers a

Binary‐to‐Ternary Reconfigurable Transistors Using Plasma‐Assisted MoS2
Advanced Functional Materials, EarlyView.A binary‐to‐ternary reconfigurable transistor is demonstrated using a dual‐gated molybdenum disulfide homojunction with localized O2 plasma treatment. The device exhibits on/intermediate and intermediate/off current ratios of 102 and 104, respectively, and the intermediate state is electrically tunable in the ternary mode.
