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…
Discontinuous character of the ultrafast exciton Mott transition in monolayer WS
Subhadra Mohapatra, Samuel Palato, Nicholas Olsen +2
There are conflicting predictions and reports on the character of the exciton Mott transition (EMT) in monolayer transition metal dichalcogenides. It could be either a discontinuou…
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…
Real-Space Imaging of the Band Topology of Transition Metal Dichalcogenides
Madisen Holbrook, Julian Ingham, Daniel Kaplan +11
The topological properties of Bloch bands are intimately tied to the structure of their electronic wavefunctions within the unit cell of a crystal. Here, we show that scanning tunn…
A 2D van der Waals Material for Terahertz Emission with Giant Optical Rectification
Taketo Handa, Chun-Ying Huang, Yiliu Li +7
Exfoliation and stacking of two-dimensional (2D) van der Waals (vdW) crystals have created unprecedented opportunities in the discovery of quantum phases. A major obstacle to the a…
Coupling of Electronic Transitions to Ferroelectric Order in a 2D Semiconductor
Chun-Ying Huang, Daniel G. Chica, Zhi-Hao Cui +16
A ferroelectric material often exhibits a soft transvers optical (TO) phonon mode which governs it phase transition. Charge coupling to this ferroelectric soft mode may further med…
Twisted nonlinear optics in monolayer van der Waals crystals
Tenzin Norden, Luis M. Martinez, Nehan Tarefder +13
In addition to a plethora of emergent phenomena, the spatial topology of optical vortices enables an array of applications spanning communications to quantum photonics. Nonlinear o…
Impact of a monolayer on the nanoscale thermoelastic response of silicon heterostructures
Davide Soranzio, Denny Puntel, Manuel Tuniz +18
Understanding the thermoelastic response of a nanostructure is crucial for the choice of materials and interfaces in electronic devices with improved and tailored transport propert…
Spontaneous Exciton Dissociation in Transition Metal Dichalcogenide Monolayers
Taketo Handa, Madisen A. Holbrook, Nicholas Olsen +8
Since the seminal work on MoS2 monolayers, photoexcitation in atomically-thin transition metal dichalcogenides (TMDCs) has been assumed to result in excitons with large binding ene…
