Magnetic Precursor to the Structural Phase Transition in V2O3

Advanced Electronic Materials, EarlyView.
V₂O₃, a model Mott insulator, undergoes a metal‐insulator transition linked to structural and magnetic transitions, though the underlying mechanism remains unclear. Through muon‐spin rotation and X‐ray diffraction on strain‐engineered thin films, a magnetic precursor to the structural transition is identified, emphasizing the key role of magnetism in ...

A Strategic Approach for Enhanced p‐Type Doping of WSe2 p‐MOSFETs Using an Atomic Oxidation Process

Advanced Electronic Materials, EarlyView.
A robust approach to p‐type doping in monolayer WSe2 is demonstrated using phase‐engineered WSeyOx / WSe2 / WSeyOx heterostructures formed via atomic oxidation. Self‐limited surface oxidation enables non‐destructive charge transfer doping while preserving intrinsic channel properties.

Nonlinear Optical Imaging of Entangled Heterophase Polydomains in Ferroelectric BZT Films

Advanced Electronic Materials, EarlyView.
A non‐destructive, label‐free nonlinear optical imaging methodology is presented for the characterization of heterophase polydomains in ferroelectric materials. Through advanced second‐harmonic generation microscopy, tetragonal and rhombohedral domain structures are visualized directly, and local strain distributions in BaZr₀.₂Ti₀.₈O₃ films are ...

Determining Exciton Diffusion Length in Organic Semiconductors: Unifying Macro‐ and Microscopic Perspectives

Advanced Energy Materials, EarlyView.
Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells

Advanced Energy Materials, EarlyView.
Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize
