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…
Roadmap for Photonics with 2D Materials
F. Javier García de Abajo, D. N. Basov, Frank H. L. Koppens +145
Triggered by the development of exfoliation and the identification of a wide range of extraordinary physical properties in self-standing films consisting of one or few atomic layer…
Spatiotemporal imaging of nonlinear optics in van der Waals waveguides
Ding Xu, Zhi Hao Peng, Chiara Trovatello +6
Van der Waals (vdW) semiconductors have emerged as promising platforms for efficient nonlinear optical conversion, including harmonic and entangled photon generation. Although majo…
Time-dependent screening explains the ultrafast excitonic signal rise in 2D semiconductors
Valerie Smejkal, Florian Libisch, Alejandro Molina-Sanchez +2
We calculate the time evolution of the transient reflection signal in an MoS monolayer on a SiO/Si substrate using first-principles out-of-equilibrium real-time methods. Ou…
The ultrafast onset of exciton formation in 2D semiconductors
Chiara Trovatello, Florian Katsch, Nicholas J. Borys +11
The equilibrium and non-equilibrium optical properties of single-layer transition metal dichalcogenides (TMDs) are determined by strongly bound excitons. Exciton relaxation dynamic…
Strongly coupled coherent phonons in single-layer MoS
C. Trovatello, H. P. C. Miranda, A. Molina-Sánchez +15
We present a transient absorption setup combining broadband detection over the visible-UV range with high temporal resolution (20fs) which is ideally suited to trigger and de…
