MAGNETIC EFFECTS ON TRIPLET EXCITON INTERACTIONS
WebA magnetic exciton is one such rare example found in magnetic insulators. However, it is relatively rare to observe that external variables control matter-light interaction. Here, it is reported that the broken inversion symmetry of multiferroicity can act as an external knob enabling magnetic excitons in the van der Waals antiferromagnet NiI 2 . WebFeb 18, 2024 · Herein, utilizing low-temperature magneto-photoluminescence (PL) measurement, we provide the direct PL spectral feature of the dark exciton in CsPbBr 3 … tick tack toe unblocked

WebOct 27, 2024 · The pair of green arrows illustrates the exciton scattering paths, with the arrow thickness being proportional to the scattering amplitude. The red dome is the calculated exciton center-of-mass wave function, strongly localized on the skyrmion. (b) DFT-based spin-resolved band structure of the CrI 3 monolayer. Color codes the spin … All our NiPS3 crystals were grown by a chemical vapour transport method18. We handled all the powdered elements (purchased from Sigma-Aldrich)—nickel (99.99% purity), phosphorus (99.99%) and sulfur (99.998%)—inside an argon-filled glove box in order to minimize possible oxidation. They were weighed and … See more Few-layer NiPS3 samples were prepared on Si substrates with a 285 nm layer of SiO2 by mechanical exfoliation from a bulk single crystal of … See more We used a NiPS3 single crystal of about 1 mm × 0.7 mm for the RIXS experiments at the I21 beamline of the Diamond Light Source, UK.
