Tuning Optoelectronic Properties and Photoelectrochemical Performance of β‐TaON via Vanadium Doping

Small, EarlyView.
Vanadium‐doped β‐TaON is studied to elucidate how controlled cation substitution modulates crystal and electronic structures and photoelectrochemical performance. Moderate vanadium incorporation (<10 at.%) retains phase purity, narrows the bandgap, and improves charge transport, whereas excessive doping (>10 at.%) induces secondary phases that suppress

Finite Size‐Effects in Martensite Microstructure of Magnetic Shape Memory Films

Small, EarlyView.
Magnetic shape memory alloys are a promising multifunctional material system for integration into microsystems. Their multifunctionality arises from the coexistence of ferroelasticity and ferromagnetism. While size‐effects in ferromagnetic microstructure are well understood, corresponding experiments on the ferroelastic microstructure are sparse.

Fast Switching and High Polarization in Ferroelectric Hf0.5Zr0.5O2 Films

Small Science, EarlyView.
Ferroelectric Hf0.5Zr0.5O2 thin films are grown under tuned redox conditions to simultaneously achieve high polarization and fast switching. Control of defect dipoles and internal fields enables stable domain wall motion without compromising performance. This work provides a pathway for designing fast and energy‐efficient ferroelectric devices.

Universal Fabrication of Graphene/Perovskite Oxide Hybrid Heterostructures

Small Structures, EarlyView.
This study presents a universal, catalyst‐free method for the direct growth of monolayer graphene on perovskite oxides without the need for transfer. The process yielded uniform graphene formation across different insulating substrates under identical conditions, revealing a substrate‐independent growth mechanism.

Strain Engineering of SrTiO3

, 2019
Due to their tendency to form ionic states, transition metal oxides and especially SrTiO3 exhibit extraordinary ferroelectric properties. However, they typically exhibit these extraordinary properties close to the ferroelectric phase transition temperature, which usually deviates significantly room temperature.
