Re-evaluating photoluminescent defects in Cu2_2O

Using density functional theory with rigorous convergence and consistency checks, this study refutes the long-held assignment of specific photoluminescence lines in Cu2_2O to copper and oxygen vacancies, demonstrating instead that oxygen interstitials, copper interstitials, and a specific split copper vacancy are the only native defects responsible for robust in-gap states.

Engineering Quantum Phases in Two Dimensions via Vacancy-Induced Electronic Reconstruction

This paper demonstrates that atomic vacancies in two-dimensional semiconductors can actively engineer topological phase transitions, such as quantum spin Hall and quantum anomalous Hall states, by forming an emergent electronic subspace through the hybridization of defect states, thereby transforming trivial insulators into topological quantum matter.

Spontaneous Polarization Suppression of Exciton-Exciton Annihilation in 3R-Stacked MoS2_2 Bilayers

This study demonstrates that the spontaneous polarization inherent in 3R-stacked MoS2_2 bilayers suppresses exciton-exciton annihilation through repulsive dipole-dipole interactions, thereby enabling high-density excitonic regimes essential for efficient optoelectronic applications.

Thermodynamic accessibility of Li-Mn-Ti-O cation disordered rock-salt phases

By combining first-principles calculations and X-ray diffraction experiments, this study maps the Li-Mn-Ti-O phase diagram to reveal that specific disordered rock-salt compositions exhibit order-disorder transition temperatures significantly lower than conventional synthesis conditions, thereby enabling optimized, lower-temperature production of high-energy-density battery cathodes.

Single-pair charge-2 Weyl-Dirac composite semimetals

By systematically classifying magnetic space groups and predicting a realization in chiral boron allotropes, this study resolves the long-standing question of whether a minimal heterogeneous configuration of a single Weyl point and a single Dirac point can exist, revealing it as a unique topological state in specific chiral space groups that yields ultralong Fermi arcs.
