Correlating activity and defects in (photo)electrocatalysts using in-situ transient optical microscopy
Camilo A. Mesa, Michael Sachs, Ernest Pastor +8
(Photo)electrocatalysts capture sunlight and use it to drive chemical reactions such as water splitting to produce H2. A major factor limiting photocatalyst development is their la…
Direct Observation of Ultrafast Singlet Exciton Fission in Three Dimensions
Arjun Ashoka, Nicolas Gauriot, Aswathy V. Girija +7
We present quantitative ultrafast interferometric pump-probe microscopy capable of tracking of photoexcitations with sub 10 nm spatial precision in three dimensions with 15 fs temp…
Directed Energy Transfer from Monolayer to NIR Emitting PbS-CdS Quantum Dots
Arelo O. A Tanoh, Nicolas Gauriot, Géraud Delport +9
Heterostructures of two-dimensional (2D) transition metal dichalcogenides (TMDs) and inorganic semiconducting zero-dimensional (0D) quantum dots (QDs) offer unique charge and energ…
Optical and electronic properties of colloidal CdSe Quantum Rings
James Xiao, Yun Liu, Violette Steinmetz +14
Luminescent colloidal CdSe nanorings are a new type of semiconductor structure that have attracted interest due to the potential for unique physics arising from their non-trivial t…
Ultrafast Tracking of Exciton and Charge Carrier Transport in Optoelectronic Materials on the Nanometer Scale
Christoph Schnedermann, Jooyoung Sung, Raj Pandya +6
We present a novel optical transient absorption and reflection microscope based on a diffraction-limited pump pulse in combination with a wide-field probe pulse, for the spatio-tem…
