Two-dimensional plasma density evolution local to the inversion layer during sawtooth crash events using Beam Emission Spectroscopy
Sayak Bose, William Fox, Dingyun Liu +4
We present methods for analyzing Beam Emission Spectroscopy (BES) data to obtain the plasma density evolution associated with rapid sawtooth crash events at the DIII-D tokamak. BES…
Laboratory study of the torus instability threshold in solar-relevant, line-tied magnetic flux ropes
Andrew Alt, Clayton E. Myers, Hantao Ji +7
Coronal mass ejections (CME) occur when long-lived magnetic flux ropes (MFR) anchored to the solar surface destabilize and erupt away from the Sun. This destabilization is often de…
Suppressing Diffusion-Mediated Exciton Annihilation in 2D Semiconductors Using the Dielectric Environment
Aaron J. Goodman, Der-Hsien Lien, Geun Ho Ahn +5
Atomically thin semiconductors such as monolayer MoS2 and WS2 exhibit nonlinear exciton-exciton annihilation at notably low excitation densities (below ~10 excitons/um2 in MoS2). H…
Ultrafast Charge Transfer at a Quantum Dot/2D Materials Interface Probed by Second Harmonic Generation
Aaron J. Goodman, Nabeel S. Dahod, William A. Tisdale
Hybrid quantum dot (QD) / transition metal dichalcogenide (TMD) heterostructures are attractive components of next generation optoelectronic devices, which take advantage of the sp…
Phase-Modulated Degenerate Parametric Amplification Microscopy
Yunan Gao, Aaron J. Goodman, Pin-Chun Shen +2
Second-order nonlinear optical interactions, including second harmonic generation (SHG) and sum-frequency generation (SFG), can reveal a wealth of information about chemical, elect…
Exciton Trapping Is Responsible for the Long Apparent Lifetime in Acid-Treated MoS2
Aaron J. Goodman, Adam P. Willard, William A. Tisdale
Here, we show that deep trapped "dark" exciton states are responsible for the surprisingly long lifetime of band-edge photoluminescence in acid-treated single-layer MoS2. Temperatu…
