Nonlinear Anisotropic Dielectric Metasurfaces for Ultrafast Nanophotonics

Autor: Yuri S. Kivshar, Lucia Ganzer, Mohsen Rahmani, Costantino De Angelis, Ben Hopkins, Giuseppe Della Valle, Tatjana Stoll, Dragomir N. Neshev, Giulio Cerullo, Stefano Longhi

Publikováno v: ACS Photonics. 4:2129-2136

We report on the broadband transient optical response from anisotropic nanobrick amorphous silicon particles, exhibiting Mie-type resonances. A quantitative model is developed to identify and disentangle the three physical processes that govern the u

Two-Dimensional Electronic Spectroscopy Unravels sub-100 fs Electron and Hole Relaxation Dynamics in Cd-Chalcogenide Nanostructures

Autor: Francesco Tassone, Federico Branchi, Julien Réhault, Ilka Kriegel, Tatjana Stoll, Francesco Scotognella, Giulio Cerullo

Publikováno v: The Journal of Physical Chemistry Letters

We use two-dimensional electronic spectroscopy (2DES) to disentangle the separate electron and hole relaxation pathways and dynamics of CdTe nanorods on a sub-100 fs time scale. By simultaneously exciting and probing the first three excitonic transit

Unraveling electron and hole relaxation dynamics in colloidal CdTe nanorods: a two-dimensional electronic spectroscopy study

Autor: Giulio Cerullo, Francesco Tassone, Ilka Kriegel, Julien Réhault, Federico Branchi, Francesco Scotognella, Tatjana Stoll

Publikováno v: Ultrafast Phenomena and Nanophotonics XXI.

In this work we study the ultrafast exciton dynamics in CdTe nanorods by using two-dimensional electronic spectroscopy (2DES). By simultaneously exciting the lowest three excitonic transitions (i.e. S1, S2 and S3) we extract the electron and hole rel

Dissecting charge relaxation pathways in CdSe/CdS nanocrystals using femtosecond two-dimensional electronic spectroscopy

Autor: Kenneth L. Knappenberger, Chongyue Yi, Julien Réhault, Jeremy W. Jarrett, A. Oriana, Tatjana Stoll, Federico Branchi, Giulio Cerullo

Exciton relaxation dynamics of CdSe and quasi-type-II CdSe/CdS core/shell nanocrystals were examined using femtosecond two-dimensional electronic spectroscopy (2DES). The use of 2DES allowed for determination of structure-specific and state-resolved
