Inhomogeneous saturation of excitons in monolayer transition-metal dichalcogenides
Blake T. Hipsley, Adam Alfrey, Steven T. Cundiff
We observe that the apparent inhomogeneous broadening, as measured by two-dimensional coherent spectroscopy (2DCS), of the exciton resonance in transition-metal dichalcogenide mono…
Quantitative Benchmarking of Spectroscopic Homogeneous and Inhomogeneous Linewidth Separation
Adam Alfrey, Cole Tait, Joshua R. Hendrickson +1
Separating homogeneous and inhomogeneous contributions to a spectral linewidth is essential for connecting optical spectra to microscopic dephasing and disorder. We quantitatively…
Revealing Strain and Disorder in Transition-Metal Dichalcogenides Using Hyperspectral Photoluminescence Imaging
Adam Alfrey, Cole Tait, Takashi Taniguchi +2
Hyperspectral photoluminescence (HSPL) imaging provides spatially resolved spectral information for monolayer transition-metal dichalcogenides (TMDs), enabling the detection of sub…
Magneto-Moiré Excitons in Twisted Bilayer CrSBr
Qiuyang Li, Anton Shubnic, Nishkarsh Agarwal +15
Moiré superlattices in van der Waals materials have revolutionized the study of electronic and excitonic systems by creating periodic electrostatic potentials. Extending this conce…
Twist Engineering of Anisotropic Excitonic and Optical Properties of a Two-Dimensional Magnetic Semiconductor
Qiuyang Li, Xiaohan Wan, Senlei Li +12
Two dimensional (2D) van der Waals (vdW) magnetic semiconductors are a new class of quantum materials for studying the emergent physics of excitons and spins in the 2D limit. Twist…
Large Exciton Binding Energy in the Bulk van der Waals Magnet CrSBr
Shane Smolenski, Ming Wen, Qiuyang Li +13
Excitons, bound electron-hole pairs, influence the optical properties in strongly interacting solid state systems. Excitons and their associated many-body physics are typically mos…
Magnetic Exciton-Polariton with Strongly Coupled Atomic and Photonic Anisotropies
Qiuyang Li, Xin Xie, Adam Alfrey +10
Anisotropy plays a key role in science and engineering. However, the interplay between the material and engineered photonic anisotropies has hardly been explored due to the vastly…
Imaging dynamic exciton interactions and coupling in transition metal dichalcogenides
Torben L. Purz, Eric W. Martin, William G. Holtzmann +6
Transition metal dichalcogenides (TMDs) are regarded as a possible materials platform for quantum information science and related device applications. In TMD monolayers, the dephas…
Nanoscale trapping of interlayer excitons in a 2D semiconductor heterostructure
Daniel N. Shanks, Fateme Mahdikhanysarvejahany, Christine Muccianti +8
For quantum technologies based on single excitons and spins, the deterministic placement and control of a single exciton is a long-standing goal. MoSe2-WSe2 heterostructures host s…
Temperature dependent moiré trapping of interlayer excitons in MoSe2-WSe2 heterostructures
Fateme Mahdikhanysarvejahany, Daniel N. Meade, Christine Muccianti +12
MoSe2-WSe2 heterostructures host strongly bound interlayer excitons (IXs) which exhibit bright photoluminescence (PL) when the twist-angle is near 0° or 60°. Over the past several…
2D Semiconductor Nonlinear Plasmonic Modulators
Matthew Klein, Bekele H. Badada, Rolf Binder +8
A plasmonic modulator is a device that controls the amplitude or phase of propagating plasmons. In a pure plasmonic modulator, the presence or absence of a pump plasmonic wave cont…
