Structural, Superconducting and Magnetic Properties of Oxygen‐Annealed Fe1+yTe Thin Films

open access: yesAdvanced Physics Research, EarlyView.
FeTe:Ox films exhibit exchange bias below their Néel temperatures, which coexists with superconductivity. STEM analysis reveals the structural changes induced by oxygen treatment. DFT calculations indicate that interstitial oxygen suppresses antiferromagnetism and promotes superconductivity.

A Prospective, Multicenter, Open Label Study Investigating the Implementation of a Standardized Algorithm for Coronary CaLcificatiOn With PlaquE Modification Using UltraSound Guidance to Improve Procedural and Clinical Outcomes (CYCLOPES): Design and Rationale of the CYCLOPES Trial

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Introduction Moderate‐to‐severe calcification is present in ~20%–30% of patients undergoing coronary angiography. Coronary lesion modification is often necessary to facilitate optimal stent delivery and expansion, with several dedicated devices now approved for calcium modification before stent implantation. The CYCLOPES study aims to evaluate

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

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
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

Origins of the Pangkaimen Au Deposit in the Northern Great Xing'an Range, China: Evidence From Geochronological, Geochemical, Fluid Inclusion, and H–O–S–Pb Isotope Data

open access: yesGeological Journal, EarlyView.
The Pangkaimen Au–Ag deposits belong to the epithermal Au deposits, which are of great significance for guiding the research and development of this type of gold deposit. Metallogenic model diagram of Pangkaimen Au–Ag deposit. ABSTRACT The gold (Au) metallogenic belt in the northern Great Xing'an Range is characterised by the wide occurrence of the ...

Radioluminescence and photoluminescence of Th:CaF$_2$ crystals

open access: yes, 2015
We study thorium-doped CaF$_2$ crystals as a possible platform for optical spectroscopy of the Th-229 nuclear isomer transition. We anticipate two major sources of background signal that might cover the nuclear spectroscopy signal: VUV-photoluminescence,

Elucidating the origin of open‐circuit voltage in ternary organic solar cells with a nonfullerene and a fullerene acceptor

open access: yesInfoMat, EarlyView.
Fullerenes tend to alloy with polymer:nonfullerene acceptor hosts, yielding composition‐dependent increases in open‐circuit voltage while recombination remains governed by the charge‐transfer state energy and is independent of the nature of the third component.

Microwave pumped excimer lasers

open access: yesConference on Lasers and Electro-Optics, 1981
Microwave excitation is a simple practical method of pumping high-pressure rare-gas-halide laser systems which avoids the discharge instabilities of typical avalanche discharges. Thus long pulse high-repetition rate operation is possible. In addition, the device can be easily constructed with high-vacuum halogen compatible materials and is free from ...

Domain engineered gallium oxide phototransistors enabling intelligent ultraviolet vision with dynamic gating

open access: yesInfoMat, EarlyView.
Single‐domain Si‐doped β‐Ga2O3 thin films grown on off‐axis sapphire eliminate domain boundaries, improving transport and photogating. Gate‐pulse modulation suppresses persistent photoconductivity, yielding ultrafast response and high detectivity. Integrated into a 24 × 24 array, the devices enable high frame rate DUV imaging and energy‐efficient ...
