Phason-mediated interlayer exciton diffusion in WS2/WSe2 moiré heterostructure
Antonio Rossi, Jonas Zipfel, Indrajit Maity +13
Moiré potentials in two-dimensional materials have been proven to be of fundamental importance to fully understand the electronic structure of van der Waals heterostructures, from…
Graphene-driven correlated electronic states in one dimensional defects within WS
Antonio Rossi, John C. Thomas, Johannes T. Küchle +19
Tomonaga-Luttinger liquid (TLL) behavior in one-dimensional systems has been predicted and shown to occur at semiconductor-to-metal transitions within two-dimensional materials. Re…
Hyperspectral imaging of excitons within a moiré unit-cell with a sub-nanometer electron probe
Sandhya Susarla, Mit H. Naik, Daria D. Blach +9
Electronic and optical excitations in two-dimensional moiré systems are uniquely sensitive to local atomic registries, leading to materials- and twist-angle specific correlated ele…
Nonvolatile Electric-Field Control of Inversion Symmetry
Lucas Caretta, Yu-Tsun Shao, Jia Yu +20
In condensed-matter systems, competition between ground states at phase boundaries can lead to significant changes in material properties under external stimuli, particularly when…
Autonomous Investigations over WS and Au{111} with Scanning Probe Microscopy
John C. Thomas, Antonio Rossi, Darian Smalley +14
Individual atomic defects in 2D materials impact their macroscopic functionality. Correlating the interplay is challenging, however, intelligent hyperspectral scanning tunneling sp…
Electric Field Control of Chirality
Piush Behera, Molly A. May, Fernando Gómez-Ortiz +18
Polar textures have attracted significant attention in recent years as a promising analog to spin-based textures in ferromagnets. Here, using optical second harmonic generation bas…
Ultrafast optical melting of trimer superstructure in layered 1T'-TaTe2
Khalid M. Siddiqui, Daniel B. Durham, Frederick Cropp +12
Quasi-two-dimensional transition-metal dichalcogenides are a key platform for exploring emergent nanoscale phenomena arising from complex interactions. Access to the underlying deg…
Enhanced nonlinear interaction of polaritons via excitonic Rydberg states in monolayer WSe2
Jie Gu, Valentin Walther, Lutz Waldecker +7
Strong optical nonlinearities play a central role in realizing quantum photonic technologies. In solid state systems, exciton-polaritons, which result from the hybridization of mat…
Rigid band shifts in two-dimensional semiconductors through environmental screening
Lutz Waldecker, Archana Raja, Malte Rösner +9
We investigate the effects of environmental dielectric screening on the electronic dispersion and the band gap in the atomically-thin, quasi two-dimensional (2D) semiconductor WS$_…
Intrinsic Lifetime of Higher Excitonic States in Tungsten Diselenide Monolayers
Samuel Brem, Jonas Zipfel, Malte Selig +7
The reduced dielectric screening in atomically thin transition metal dichalcogenides allows to study the hydrogen-like series of higher exciton states in optical spectra even at ro…
Coulomb engineering of the bandgap in 2D semiconductors
Archana Raja, Andrey Chaves, Jaeeun Yu +13
The ability to control the size of the electronic bandgap is an integral part of solid-state technology. Atomically-thin two-dimensional crystals offer a new approach for tuning th…
Excitonic linewidth and coherence lifetime in monolayer transition metal dichalcogenides
Malte Selig, Gunnar Berghäuser, Archana Raja +7
Atomically thin transition metal dichalcogenides (TMDs) are direct-gap semiconductors with strong light-matter and Coulomb interaction. The latter accounts for tightly bound excito…
