X-ray driven displacive excitation of coherent phonons
Oleg Dogadov, Remi Claude, Christoph Emeis +29
Modulating electron-phonon coupling offers a route to control structural displacements and tune material functionality. Valence-to-conduction band transitions, however, provide lim…
Nonequilibrium dynamics of high energy transitions in monolayer WSe
Oleg Dogadov, Jorge Cervantes-Villanueva, Nicholas Olsen +6
High-energy optical transitions in monolayer transition-metal dichalcogenides exhibit characteristics that are markedly distinct from those of lower-lying band-edge excitons. These…
Excitonic Mott transition without population inversion
Oleg Dogadov, Armando Genco, Allison R. Cadore +12
Exciton dissociation via the excitonic Mott transition (EMT) governs the high-density optical response of semiconductors and sets fundamental limits for optoelectronic devices. The…
Valleytronics in 2D Materials Roadmap
Kyle L. Seyler, Giancarlo Soavi, Bent Weber +30
Valleytronics exploits non-equivalent energy extrema in the electronic band structure of crystalline solids -- the valley degree of freedom -- to encode, manipulate, and read out i…
Dissecting intervalley coupling mechanisms in monolayer transition metal dichalcogenides
Oleg Dogadov, Henry Mittenzwey, Micol Bertolotti +8
Monolayer (1L) transition metal dichalcogenides (TMDs) provide a unique opportunity to control the valley degree of freedom of optically excited charge carriers due to the spin-val…
Photo-generated charge-transfer excitons in NiO revealed by ultrafast time-resolved resonant inelastic x-ray scattering
Giacomo Merzoni, Leonardo Martinelli, Sergii Parchenko +32
Strong electronic correlation can lead to insulating behavior and to the opening of large optical gaps, even in materials with partly filled valence shells. Although the non-equili…
Time-domain observation of interlayer exciton formation and thermalization in a MoSe/WSe heterostructure
Veronica R. Policht, Henry Mittenzwey, Oleg Dogadov +11
Vertical heterostructures (HS) of transition metal dichalcogenides (TMDs) host interlayer excitons (ILX), with electrons and holes residing in different layers. With respect to the…
Parametric Nonlinear Optics with Layered Materials and Related Heterostructures
O. Dogadov, C. Trovatello, B. Yao +2
Nonlinear optics is of crucial importance in several fields of science and technology with applications in frequency conversion, entangled-photon generation, self-referencing of fr…
