Determining the carrier decay kinetics in QCSE-exhibiting materials: An accurate interpretation of transient absorption spectroscopy data

Carrier dynamics is fundamental in the optimal performance of optoelectronic devices. TAS experiments can be used to study carrier dynamics at a particular wavelength. However, the
$\Delta \alpha$
kinetics in QCSE-exhibiting materials turns out to be only approximate. This paper proposes a more accurate method to determine carrier dynamics.
