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

Hard x-ray photoelectron spectroscopy (HAXPES) is establishing itself as an essential
technique for the characterisation of materials. The number of specialised photoelectron …

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

Many textbook physical effects in crystals are enabled by some specific symmetries. In
contrast to such 'apparent effects','hidden effect X'refers to the general condition where the …

It has been recently shown that monolayers of transition metal dichalcogenides (TMDs) in
the 2H structural phase exhibit relatively large orbital Hall conductivity plateaus within their …

Monolayers of transition metal dichalcogenides (TMDs) in the 2 H structural phase have
been recently classified as higher-order topological insulators (HOTIs), protected by C 3 …

Recent experimental observation of an unexpectedly large current-induced spin-orbit torque
in surface oxidized Cu on top of a ferromagnet pointed to a possibly prominent role of the …

The dynamics of momentum-dark exciton formation in transition metal dichalcogenides is
difficult to measure experimentally, as many momentum-indirect exciton states are not …

Using an effective Dirac model, we study the orbital Hall effect (OHE) in bilayers of transition
metal dichalcogenides with 2H stacking (2H-TMD). We use first-order perturbation theory in …

Excitons, Coulomb‐bound electron–hole pairs, are the fundamental excitations governing
the optoelectronic properties of semiconductors. Although optical signatures of excitons …
