Effect of the screening on the polaron mass in a semiconductor hollow nanocylinder

The effect of the screening effect of the electron–phonon interaction on a weakly coupling Frohlich polaron mass has been investigated in a semiconductor hollow nanocylinder (HNC). General analytical expressions for the polaron mass have been obtained in arbitrary values of nanocylinder radius r0, t...
