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…
Nonequilibrium dynamics of localized and delocalized excitons in colloidal quantum dot solids
Elizabeth M. Y. Lee, William A. Tisdale, Adam P. Willard
Self-assembled quantum dot (QD) solids are a highly tunable class of materials with a wide range of applications in solid-state electronics and optoelectronic devices. In this pers…
Ideal Bandgap in a 2D Ruddlesden-Popper Perovskite Chalcogenide for Single-junction Solar Cells
Shanyuan Niu, Debarghya Sarkar, Kristopher Williams +12
Transition metal perovskite chalcogenides (TMPCs) are explored as stable, environmentally friendly semiconductors for solar energy conversion. They can be viewed as the inorganic a…
High Repetition-Rate Femtosecond Stimulated Raman Spectroscopy with Fast Acquisition
Matthew N. Ashner, William A. Tisdale
Time-resolved femtosecond stimulated Raman spectroscopy (FSRS) is a powerful tool for investigating ultrafast structural and vibrational dynamics in light absorbing systems. Howeve…
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…
