This study utilizes synchrotron X-ray diffraction and calorimetry to demonstrate that the NASICON-type NaFeCr(PO) undergoes a temperature-driven order-disorder transition where Na-ion redistribution within the [FeCr(PO)] framework drives a symmetry-lowering structural change from a monoclinic ordered phase to a rhombohedral disordered phase.
This study demonstrates that the honeycomb CuSe monolayer on Cu(111) undergoes a reversible structural transition between stripe and hole phases, which is driven by the interplay of selenium coverage and annealing temperature.
This paper introduces efficient quantum circuits for fermionic excitation operators on ion trap quantum computers that leverage the global Mølmer-Sørensen interaction to achieve optimal parallelism, reducing gate counts by factors of 2 and 4 for single and double excitations respectively, thereby significantly improving speed and error performance.
This study synthesizes and characterizes eight (Sb,Bi)(S,Se)(Br,I) chalcohalide compounds via physical vapor deposition, revealing tunable bandgaps and efficient photoluminescence while establishing structure-property relations through experimental carrier dynamics analysis and DFT calculations to guide their optimization for optoelectronic applications.
This study utilizes temperature-dependent Raman and photoluminescence spectroscopy on encapsulated selenium thin films to demonstrate that short-range structural disorder and grown-in stress, rather than being intrinsic, are highly sensitive to processing variations and act as dominant non-radiative recombination centers that limit photovoltaic performance, thereby highlighting the critical need for precise synthesis control to optimize selenium-based solar technologies.
This study demonstrates that cation substitution and crystal symmetry in inorganic antiperovskite nitrides () critically govern nonradiative recombination dynamics, with hexagonal achieving the longest carrier lifetimes through a synergistic balance of reduced nonadiabatic coupling and enhanced dephasing.
This study reveals that while the body-centered tetragonal phase is thermodynamically stable for small zinc oxide nanoparticles, the atom-by-atom deposition process drives a phase transition to the more stable wurtzite structure through a specific ion redistribution that compensates for emerging polar facets.
This paper establishes a comprehensive group-theory framework for assigning symmetry labels and total crystal angular momentum to excitonic states, enabling the derivation of selection rules, conservation laws, and enhanced computational efficiency for the Bethe-Salpeter equation, as demonstrated through applications to LiF, monolayer MoSe2, and bulk hBN.
This study demonstrates that substituting the A-site cation in carbide antiperovskites from Ca to Sr significantly modulates carrier lifetimes and relaxation dynamics, with CaCSe exhibiting an 18-fold longer lifetime than SrCSe due to enhanced lattice fluctuations that suppress nonradiative recombination.
This paper reports that the layered diluted magnetic semiconductor (Ba,K)(Cd,Mn)As exhibits bulk ferromagnetism and a colossal negative magnetoresistance of approximately -100% at low fields, establishing it as a promising platform for low-temperature magnetoresistive applications.
