Localized Excitons and Exciton-Phonon Coupling in Antiferromagnetic AgCrP2S6
Jessica McDivitt, Dimitar Pashov, Mark van Schilfgaarde +4
AgCrP2S6 combines a low-symmetry thiophosphate framework with an antiferromagnetic Cr sublattice and nonmagnetic Ag sites, providing a setting in which covalency and magnetic local…
Bright and Dark Excitons in CrSBr: Local Ligand-Field Character and Band-Coherent Optical Selection Rules
Swagata Acharya, Jessica McDivitt, Dimitar Pashov +3
Magnetic van der Waals semiconductors such as CrSBr host an intricate exciton landscape whose physical interpretation has converged only recently. A many-body Feynman diagrammatic…
Spin-quenching in molecule-transition-metal-dichalcogenide heterostructure through inverse proximity effect
Swagata Acharya, Dimitar Pashov, Daphne Lubert-Perquel +2
A functional heterostructure is central to integrated circuitry in quantum photonics, optoelectronics, neuromorphic computing, spintronics, and straintronics. Recently, heterostruc…
Modulating Endothermic Singlet Fission by Controlling Radiative Rates in Perylene Dimers
Nadezhda V. Korovina, Shea OSullivan, Jennica Kelm +3
Endothermic singlet fission (SF), an exciton multiplication process that produces a pair of high-energy triplet excitons (T1T1), is appealing for photovoltaic or photoelectrochemic…
