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…
