Hopping mechanism and Griffiths singularity in La0.7Ca0.25Sr0.05MnO3/Mn3O4 composite nanoparticles
This study investigates the electronic and magnetic properties of La0.7Ca0.25Sr0.05MnO3/Mn3O4 composite nanoparticles, focusing on the interplay between charge transport mechanisms and magnetic fluctu...
Effect of multi-physical field long-term aging on DC partial discharge of BOPP films
As the key insulation medium of dry DC capacitors, biaxially oriented polypropylene (BOPP) films are prone to partial discharge (PD) during long-term operation. To investigate the influence of long-te...
Mn3−xZnxTa2O8: Inducing multiferroelectricity in a linear magnetoelectric material
Zn for Mn substitution has been studied in the linear magnetoelectric Mn3Ta2O8. Although limited, the Zn substitution has a strong impact on the magnetic properties, inducing a spectacular, narrow, an...
Deposition of spinel IGZO thin films with increased indium contents on textured GZO templates
Spinel indium gallium zinc oxide (IGZO) has been identified as an interesting alternative to amorphous IGZO (a-IGZO) due to its higher resilience to the formation of oxygen deficiencies. Currently, it...
Magnetic field gradient-controlled plasma tuning in capacitively coupled discharges via electron beam injection
This study employs 1D particle-in-cell/Monte Carlo collision simulations to systematically investigate the modulation of capacitively coupled plasma by a unidirectional electron beam under tunable mag...
Generation of subnanosecond electromagnetic pulses by a meter-long laboratory spark discharge: A source in the near-cathode region
Ultra-wideband (UWB) subnanosecond electromagnetic pulses (EMPs) generated by a 1.3 m long positive spark discharge with a Marx generator having an operating voltage of about 1 MV are studied experime...
Band structure engineering and interfacial charge modulation in ReS2/1T′-MoS2 and ReS2/1T′-WS2 heterostructures for tunable hydrogen adsorption
In this work, we employ first-principles calculations including the spin–orbit coupling effects (SOC) to investigate the electronic structure and hydrogen evolution reaction (HER) activity of two nove...
Phase contents and piezoelectric activity in lead-free ferroelectric solid solutions containing (Ba, Ca)(Me, Ti)O3 (Me = Zr or Sn)
The coexistence of ferroelectric P4mm and Amm2 phases is studied in advanced perovskite-type (Ba0.95Ca0.05)(Zr0.05Ti0.95–x(Zn1/3Ta2/3)x)O3 and Ba0.92Ca0.08Sn0.09Ti0.91O3 solid solutions (0 ≤ x ≤ 0.02)...
Alternating-current induced-charge electrokinetic self-propulsion of metallodielectric Janus particles in confined microchannels within a wide frequency range
Induced-charge electrokinetics (ICEK) enables versatile microscale transport of asymmetric particles like Janus particles (JPs), but its underlying mechanisms remain incompletely understood—especially...
Kilovolt-class β-Ga2O3 field-plated Schottky barrier diodes with MOCVD-grown intentionally 1015 cm−3 doped drift layers
We report on the growth optimization of intentionally low-doped (1015 cm−3) high-quality beta-gallium oxide (β-Ga2O3) drift layers of up to 10 μm thick via metalorganic chemical vapor deposition (MOCV...
Carrier-assisted recombination in anatase TiO2
Differential optical transmission experiments performed on TiO2 layers reveal a carrier population decay that follows a power-law over several orders of magnitude in both time and signal amplitude, ac...
Electric-field effects on multi-photon magneto-optical absorption spectra in two-dimensional graphene: A new approach from the quantum kinetic equation method
In this paper, we perform a detailed theoretical analysis of the multi-photon magneto-optical absorption spectrum and the full width at half-maximum (FWHM) in monolayer graphene under the simultaneous...
Propulsion of diodes in aqueous suspension under alternating-current or light stimulation
Micro- or nano-diodes suspended in water can propel controllably under alternating-current fields or light without the need for fuels such as hydrogen peroxide or urea. This makes them promising candi...
Thermodynamic feasibility of nanoenergetic systems based on metal oxynitrides
A comprehensive computational study was conducted to identify and evaluate nano-energetic systems utilizing aluminum (Al) as the fuel and a range of metal oxynitrides as oxidizers. The primary objecti...
