This study utilizes 4D-STEM combined with EDS to characterize how diffusion-induced grain boundary migration in NiCr alloys alters local microstructure and generates anisotropic coherency strain, particularly at high chromium concentrations.
This paper presents simple formulae for calculating residual stresses in solid circular cylinders after severe elastic–plastic torsion, demonstrating how tension–compression asymmetry significantly alters the stress state upon unloading and providing a tool for calibrating advanced plasticity models.
This study utilizes SCAPS-1D numerical simulations to demonstrate that FeSi₂-driven SnS-based thin-film solar cells can achieve a maximum efficiency of 25.06% through optimized layer thicknesses and band alignment, while revealing that their performance is significantly limited by thermally activated interface recombination and shallow trap states.
This paper investigates information scrambling in noisy encoding-decoding quantum circuits, deriving an analytic expression for the algebraic out-of-time-order correlator that reveals a "butterfly effect" where infinitesimal noise induces macroscopic scrambling in the thermodynamic limit.
This study utilizes SCAPS-1D simulations to demonstrate that optimizing the thickness and bandgap of a Cs₂InSbCl₆-based double perovskite solar cell yields a high power conversion efficiency of nearly 28% with reduced recombination losses and acceptable thermal stability, establishing it as a promising candidate for next-generation photovoltaics.
This paper demonstrates that the nonlinear anomalous Hall effect, driven by the Berry curvature dipole and significantly enhanced by broken chiral symmetry, serves as a robust probe for detecting topological phase transitions and sign reversals in strained, valley-polarized twisted bilayer dice lattices far from charge neutrality.
This study utilizes SCAPS-1D simulations to optimize CISSe/CdS/ZnO/SLG solar cells by analyzing the impact of illumination direction, contact properties, and absorber parameters, ultimately identifying a top-illuminated configuration with an optimized bandgap and electron affinity that achieves a maximum power conversion efficiency of 33.34%.
This paper presents a modifier-free, defect-induced electrostatic anchoring strategy using CeO2 nanoparticles and BN nanosheets to create a robust silicone gel composite that achieves exceptional dielectric breakdown strength and thermal stability at 250 °C, overcoming the limitations of traditional chemical modifiers for extreme-temperature power device encapsulation.
This paper demonstrates that chlorine-based defects in 4H-SiC serve as a promising wafer-scalable platform for chip-scale quantum memories by exhibiting room-temperature spin coherence, optically detected magnetic resonance, and zero-phonon line emission across the entire telecommunication range.
This numerical study utilizing SCAPS-1D simulation demonstrates that optimizing device architecture, bandgap engineering, and transport layers can significantly enhance the power conversion efficiency of lead-free CsPbI₃ and Cs₂TiBr₆ perovskite solar cells, with the Cs₂TiBr₆-based configuration achieving a peak efficiency of 22.29%.
