Ultrafast symmetry control in photoexcited quantum dots
Burak Guzelturk, Joshua Portner, Justin Ondry +23
Symmetry control is essential for realizing unconventional properties, such as ferroelectricity, nonlinear optical responses, and complex topological order, thus it holds promise f…
Excitonic Spin-Coherence Lifetimes in CdSe Nanoplatelets Increase Significantly with Core/Shell Morphology
Phillip I. Martin, Shobhana Panuganti, Joshua C. Portner +4
We report spin-polarized transient absorption for colloidal CdSe nanoplatelets as functions of thickness (2 to 6 monolayer thickness) and core/shell motif. Using electro-optical mo…
Dynamic lattice distortions driven by surface trapping in semiconductor nanocrystals
Burak Guzelturk, Benjamin L. Cotts, Dipti Jasrasaria +26
Nonradiative processes limit optoelectronic functionality of nanocrystals and curb their device performance. Nevertheless, the dynamic structural origins of nonradiative relaxation…
Low-threshold stimulated emission using colloidal quantum wells
Chunxing She, Igor Fedin, Dmitriy S. Dolzhnikov +4
Semiconductor nanocrystals can be synthesized using inexpensive, scalable, solution-based techniques, and their utility as tunable light emitters has been demonstrated in various a…
Spin-dependent exciton quenching and intrinsic spin coherence in CdSe/CdS nanocrystals
Kipp J. van Schooten, Jing Huang, William J. Baker +3
Large surface to volume ratios of semiconductor nanocrystals cause susceptibility to charge trapping, which can modify luminescence yields and induce single-particle blinking. Opti…
