PMID: 32639717
ACS Nano. 2020 Jul 28;14(7):8528-8538. doi: 10.1021/acsnano.0c02803. Epub 2020 Jul 13.

Neutral and charged excitons (trions) in atomically thin materials offer important capabilities for photonics, from ultrafast photodetectors to highly efficient light-emitting diodes and lasers. Recent studies of van der Waals (vdW) heterostructures comprised of dissimilar monolayer materials have uncovered...

InSe as a case between 3D and 2D layered crystals for excitons.

Nature communications

Shubina TV, Desrat W, Moret M, Tiberj A, Briot O, Davydov VY, Platonov AV, Semina MA, Gil B.
PMID: 31375686
Nat Commun. 2019 Aug 02;10(1):3479. doi: 10.1038/s41467-019-11487-0.

InSe is a promising material in many aspects where the role of excitons is decisive. Here we report the sequential appearance in its luminescence of the exciton, the biexciton, and the P-band of the exciton-exciton scattering while the excitation...

Phonons in Short-Period GaN/AlN Superlattices: Group-Theoretical Analysis, .

Nanomaterials (Basel, Switzerland)

PMID: 33499097
Nanomaterials (Basel). 2021 Jan 22;11(2). doi: 10.3390/nano11020286.

We report the results of experimental and theoretical studies of phonon modes in GaN/AlN superlattices (SLs) with a period of several atomic layers, grown by submonolayer digital plasma-assisted molecular-beam epitaxy, which have a great potential for use in quantum...

Steels with sub-micrometre grain sizes usually possess high toughness and strength, which makes them promising for lightweighting technologies and energy-saving strategies. So far, the industrial fabrication of ultrafine-grained (UFG) alloys, which generally relies on the manipulation of diffusional phase...

High-Quality All-Inorganic Perovskite CsPbBr.

Nano letters

Nanostructured all-inorganic metal halide perovskites have attracted considerable attention due to their outstanding photonic and optoelectronic properties. Particularly, they can exhibit room-temperature exciton-polaritons (EPs) capable of confining electromagnetic fields down to the subwavelength scale, enabling efficient light harvesting and...

Personalized behavior management as a replacement for medications for pain control and mood regulation.

Scientific reports

Davydov DM, Galvez-Sánchez CM, Montoro CI, de Guevara CML, Reyes Del Paso GA.
