Description of Excitonic Absorption Using the Sommerfeld Enhancement Factor and Band-Fluctuations
K. Lizárraga, P. Llontop, L. A. Enrique-Morán +7
One of the challenges of excitonic materials is the accurate determination of the exciton binding energy and bandgap. The difficulty arises from the overlap of the discrete and con…
