Two-Dimensional Electronic Spectroscopy reveals liquid like structural dynamics in semiconductor perovskites

Your library or personal account may give you access

Abstract

Two-Dimensional Electronic (2DE) spectroscopy is performed on bulk nanocrystals of semiconductor perovskites of two different classes. The anti-diagonal linewidths reveal liquid like structural dynamics due to ultrafast polaron formation on the 300 fs timescale.
