Non-extensive entropy of modified Gaussian quantum dot under polaron effects

Abstract

The effect of electron–phonon (e–p) interaction on the non-extensive Tsallis entropy of a modified Gaussian quantum dot has been investigated. In this work, the LO-phonons, SO-phonons and LO + SO-phonons have been considered. It is found that the entropy increases with enhancing the confinement potential range and depth. The entropy decreases with considering the electron–phonon interaction. The electron–LO + SO-phonon interaction has the largest contribution to the entropy.
