Monolithic Oxidation Enables Ultrathin Vertically Graded Tantalum Oxide for Low‐Voltage, Low‐Variability Memristive Switching

Advanced Functional Materials, EarlyView.
Monolithic UV‐ozone oxidation of Ta forms an ultrathin Ta2O5/TaOx bilayer enabling resistive switching with a vertical defect gradient. A stoichiometric surface layer over an oxygen‐deficient sublayer promotes localized filament nucleation near the top interface, enabling low‐voltage operation, and reduced cycle‐to‐cycle variability.

Extraordinary n‐type Tellurium‐Free Thermoelectric Performance of Y‐Doped BiSe via Synergistic Effect of Vacancies and Band Engineering

Advanced Functional Materials, EarlyView.
Yttrium doping in Sb‐alloyed BiSe synergistically induces Bi vacancies and flattens conduction bands, simultaneously slashing lattice thermal conductivity by 50% and boosting the power factor. The optimized n‐type Bi0.64Sb0.3Y0.06Se delivers a peak zT of 0.91 at 393 K (average zT 0.76, 300–523 K) and an 8‐pair module with 4.6% conversion efficiency ...

Intrinsic Milk Luminescence: Underlying Mechanism and Application for Quality Visualization

Aggregate
Intrinsic milk photoluminescence (PL), though empirically observed, remains insufficiently explored in terms of mechanism and application. This work illustrates the general dual‐emission characteristics of milk and elucidates their distinct origin: blue ...

Direct Channel Implantation of B and BF2 Ions for Functional Control of Oxygen Vacancies in Oxide Semiconductor Thin Film Transistors

Advanced Functional Materials, EarlyView.
Direct channel implantation of B and BF2 ions was employed to fabricate amorphous IGZO TFTs with improved electrical and stability properties. B and BF2 implantation modulate oxygen vacancies within the IGZO channel. The field‐effect mobility of ion‐implanted IGZO TFTs was enhanced as compared to pristine IGZO TFTs.

Giant Electrostriction in Halide Perovskites Revisited With Double‐Modulation Interferometry

Advanced Functional Materials, EarlyView.
A giant electrostrictive effect in lead halide perovskites had been reported previously. This work uses sensitive interferometry to measure the electromechanical response of various halide perovskite samples. The results reveal no intrinsic electrostrictive compression. Instead, the materials expand primarily under an applied electric field as a result
