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…
Extracting Spectral Diffusion in Two-Dimensional Coherent Spectra via the Projection Slice Theorem
Cesar Perez, Steven Cundiff
A robust and streamlined method is presented for efficiently extracting spectral diffusion from two-dimensional coherent spectra by employing the projection-slice theorem. The meth…
Probing Complex Decoherence Processes in Materials for Quantum Applications
Albert Liu, Matthew W. Day, Steven T. Cundiff
The primary consideration in developing new material platforms for quantum applications is to optimize coherence. Despite its importance, decoherence processes remains challenging…
Indirect Excitons and Many-body Interactions in InGaAs Double Quantum Wells
Christopher L. Smallwood, Rachel Owen, Matthew W. Day +6
Spatially indirect excitons in semiconductor quantum wells are relevant to basic research and device applications because they exhibit enhanced tunability, delocalized wave functio…
Dephasing of InAs quantum dot p-shell excitons using two-dimensional coherent spectroscopy
Takeshi Suzuki, Rohan Singh, Galan Moody +5
The dephasing mechanisms of p-shell and s-shell excitons in an InAs self-assembled quantum dot ensemble are examined using two-dimensional coherent spectroscopy (2DCS). 2DCS provid…
Ultrafast Spin Dynamics in Optically Excited Bulk GaAs at Low Temperatures
M. Krauss, R. Bratschitsch, Z. Chen +2
This paper presents a study of electron spin dynamics in bulk GaAs at low temperatures for elevated optical excitation conditions. Our time-resolved Faraday rotation measurements y…
Temperature dependence of the electron spin g factor in GaAs
W. Zawadzki, P. Pfeffer, R. Bratschitsch +4
The temperature dependence of the electron spin factor in GaAs is investigated experimentally and theoretically. Experimentally, the factor was measured using time-resolved…
