Angle-resolved photoemission spectroscopy (ARPES), with its exceptional sensitivity to both
the binding energy and the momentum of valence electrons in solids, provides unparalleled …

Atomically thin transition metal dichalcogenides (TMDs) are 2D semiconductors with tightly
bound excitons and correspondingly strong light–matter interactions. Owing to the weak van …

Moiré superlattices in atomically thin van der Waals heterostructures hold great promise for
extended control of electronic and valleytronic lifetimes,,,,,–, the confinement of excitons in …

Abstract Interlayer excitons (ILXs)—electron–hole pairs bound across two atomically thin
layered semiconductors—have emerged as attractive platforms to study exciton …

Semiconducting two-dimensional materials with chemical formula MoSi2X4 (X= N, P, or As)
are studied by means of atomistic ground-and excited-state first-principles simulations. Full …

Atomically thin semiconductors such as transition metal dichalcogenide (TMD) monolayers
exhibit a very strong Coulomb interaction, giving rise to a rich exciton landscape. This makes …

The exciton, a bound state of an electron and a hole, is a fundamental quasiparticle induced
by coherent light–matter interactions in semiconductors. When the electrons and holes are …

We experimentally demonstrate time-resolved exciton propagation in a monolayer
semiconductor at cryogenic temperatures. Monitoring phonon-assisted recombination of …

Vertical heterostructures of transition metal dichalcogenides (TMDs) host interlayer excitons
with electrons and holes residing in different layers. With respect to their intralayer …

We demonstrate the feasibility of the time-linear scaling formulation of the GW method [Phys.
Rev. Lett. 124, 076601 (2020) PRLTAO 0031-9007 10.1103/PhysRevLett. 124.076601] for …
