Nanoscale Ripples at the Surface of SrTiO3 Irradiated by a Broad Low‐Energy Ar+ (7 keV) Ion Beam

Small, EarlyView.
Broad Ar ion beam irradiation creates self‐organized ripple nanostructures on oxide surfaces. A schematic illustrates the process, while cross‐sectional STEM imaging captures the ripple morphology. Complementary elemental mapping by EELS highlights nanoscale chemical variations, linking ion‐beam nanostructuring with structural and compositional ...

Atomic Step–Terrace Ordering Enables Unprecedentedly Low Pop‐in Stress Scatter in GaN (0001)

Small, EarlyView.
Step–terrace GaN surfaces with monoatomic topography were realized using catalyst‐referred etching. On these surfaces, pop‐ins occurred at ideal strength with a record‐low stress scatter of 2.3%, providing compelling evidence that atomic‐scale surface ordering plays a critical role in triggering incipient plasticity. Atomic‐scale surface irregularities,

Toward Efficient and Reliable Chemical Upgrading Using Solid Oxide Electrochemical Reactors, Mechanisms, Challenges, and Design Principles

Small, EarlyView.
Solid oxide electrochemical reactors (SOERs) offer a compelling pathway for coupling renewable electricity with chemical manufacturing, but their real application is still limited by low efficiency and instability. This review systematically summarizes SOER reaction mechanisms, performance‐limiting factors, and recent progress toward high‐efficiency ...

Creation of heavily La-doped SrTiO3 thermoelectric films achieved by freeze-dry pulsated orifice ejection method and laser powder bed fusion

Smart Materials in Manufacturing
Achieving both fine grain sizes and high doping levels simultaneously holds great promise for improving the dimensionless figure of merit (zT) of oxide thermoelectric materials; however, this remains a global challenge.

Energy-loss structure in core-level photoemission satellites of SrTiO3, SrTiO3 : La, and SrTiO3 : Nb

Energy-loss structure in core-level photoemission satellites of SrTiO3, SrTiO3 : La, and SrTiO3 : Nb
The core-level x-ray photoemission spectroscopy (XPS) satellites of single-crystalline SrTiO3, SrTiO3:La, and SrTiO3:Nb in situ fractured in ultrahigh vacuum were compared with the electron-energy-toss spectrum and theoretical electron-energy-loss :functions from first-principles electronic structure calculations. Experimental core-level XPS satellites
