Investigating the electronic structure of confined multiexcitons with nonlinear spectroscopies.
Samuel Palato,Hélène Seiler,Harry Baker,Colin Sonnichsen,Patrick J. Brosseau,Patanjali Kambhampati +5 more
TL;DR: This work reports on the investigation of the electronic structure of MX in colloidal CdSe QDs using time-resolved photoluminescence, state-resolving pump-probe, and two-dimensional spectroscopies and outlines the limits of the simple concept of binding energy.

TL;DR: In this article, perovskites support a new state of quantum confined excitonic polarons, which is a state of interest for quantum entanglement and magnetism.

Photophysical Action Spectra of Emission from Semiconductor Nanocrystals Reveal Violations to the Vavilov Rule Behavior from Hot Carrier Effects
TL;DR: In this article, the authors show that the latter rule of molecular spectroscopy is generally violated in semiconductor nanocrystals via hot carrier effects and show that quantum yield spectra arise because of enhanced hot carrier trapping rates.

Ultrafast hole relaxation dynamics in quantum dots revealed by two-dimensional electronic spectroscopy
Patrick J. Brosseau,Jaco J. Geuchies,Dipti Jasrasaria,Arjan J. Houtepen,Eran Rabani,Patanjali Kambhampati +5 more
TL;DR: In this paper , the population dynamics of correlated electron-hole pairs (bound excitons) in semiconducting quantum dots (QDs) is investigated for developing fundamental understanding of nanoscale photophysics as well as for the optimal design of devices.

Fifth-order two-quantum absorptive two-dimensional electronic spectroscopy of CdSe quantum dots.
TL;DR: Two-quantum variants of two-dimensional electronic spectroscopy (2DES) have previously been used to characterize multi-exciton interactions in molecules and semiconductor nanostructures though many implementations are limited by phasing procedures or non-resonant signals.
