Simple (YGa)2O3/F‐SnO2 Heterojunction‐Based Solar‐Blind Ultraviolet Photodetector Operable in Two Modes With Superb Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
Yttrium doping was proposed to expand the bandgap and inhibit the oxygen vacancies of Ga2O3 to form (YGa)2O3 alloy with reduced background carriers and trap centers. Beneficially, simple vertical‐structured (YGa)2O3/FTO heterojunction photodetectors exhibit superb performance with particularly low dark current and fast photoresponse in both self‐driven

300 Femtosecond pulses at 497 nanometer generated by an excimer laser pumped cascade of distributed feedback dye lasers.

open access: yes, 1988
The setup is a cascade of 3 lasers: A competing cavity dye laser pumped by a XeCl excimer laser, followed by two distributed feedback dye lasers. The typical durations of the pulses from the lasers are 100 ps, 5 ps, and 300 fs, respectively.

Dopant Activation in Ta‐Doped SnO2 via Postdeposition Annealing for Transparent Electrodes

open access: yesphysica status solidi (a), Volume 223, Issue 11, 10 June 2026.
This study explores the thermal activation of tantalum dopants in room‐temperature deposited tin oxide films. By optimizing deposition pressure, dopant concentration, and annealing temperature, the dominant conduction mechanism shifts from oxygen vacancies to activated dopants. The resulting transparent electrodes achieve high optical transmittance and

Effect of Atomic Layer Deposition of Ultra‐Thin Oxide on Reactivity and Durability of Perovskite Oxygen Electrodes

open access: yesAdvanced Materials, Volume 38, Issue 32, 8 June 2026.
This table of contents illustrates that the mechanism for mitigating Sr segregation depends strongly on the chemistry of the coating layer. HfO2 electrostatically stabilizes the surface by lowering the surface oxygen vacancies, which serve as the driving force for Sr migration. On the other hand, Al2O3 and Fe2O3 react with segregated Sr to form Sr‐Al‐O

Narrow band tuning with small long pulse excimer lasers

open access: yes, 1985
We discuss frequency narrowing and tuning with simple dispersion elements with small long-pulse excimer lasers. The improved performance over short-pulse lasers is discussed and attributed to the increased number of round trips.

Spin‐Orbit Torque Induced by Switchable Crystal Inversion Symmetry Breaking

open access: yesAdvanced Materials, Volume 38, Issue 31, 2 June 2026.
An exotic crystal inversion symmetry breaking in SrRuO3/BiFeO3 heterostructure is revealed, and it can be reversibly manipulated by the ferroelectric polarization of BiFeO3. This crystal inversion symmetry breaking can dramatically enhance the spin‐orbit torque efficiency in the SrRuO3 layer by more than 60%, providing an alternative to design an ...
