Tracking thermal transport in colloidal quantum dot films using in-situ time-resolved X-ray diffraction
Eliza Wieman, Nejc Nagelj, Ethan Curling +9
Colloidal quantum dots (QDs) and their thin-films are increasingly used in electronic and photonic devices replacing traditional bulk semiconductors. However, thermal properties of…
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…
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…
