Electrode electronic structure strongly affects reorganization energy
—
What the study found The study found that the electrode density of states, the distribution of electronic states available in the electrode, plays a central role in governing reorganization energy during interfacial electron transfer. The authors report that this effect outweighs the electrode’s conventionally assumed role. Why the authors say this matters The authors conclude…
Screening finds 180 materials with significant altermagnetic spin splitting
What the study found The study found 180 materials with significant altermagnetic spin splitting. These materials include both metallic and semiconducting systems, and some representative cases discussed are UCr2Si2C, NbMnP, and YRuO3. Why the authors say this matters The authors say altermagnetism is promising for next-generation spintronics because it can produce sizable spin splitting in…
Theory predicts trion signatures in ARPES spectra
What the study found The study presents a first theoretical analysis of how trions, or charged excitons, may appear in angle-resolved photoemission spectroscopy (ARPES) spectra of monolayer transition-metal dichalcogenides. It reports that the extra charge carrier changes the spectral position and shape compared with neutral excitons, and that mass-imbalanced trions are predicted to show a…
EAC-Net predicts charge density with high accuracy
What the study found EAC-Net is a model for predicting real-space charge density that combines accuracy with a physically grounded atomic decomposition. The authors report that it can achieve errors typically below 1% across the periodic table and generalize well to diverse chemical environments. Why the authors say this matters The study suggests that EAC-Net…
