Abstract

The effects of temperature T, average number of optical phonons N, the phonon frequency \(\omega \) and slab thickness d in a polar slab were investigated using the linear combination operator and unitary transformation methods. The results showed that the phonon frequency \(\omega \) increases with increasing temperature T, but the average number of optical phonons N and phonon frequency \(\omega \) decreases with the increase in slab thickness d. When the slab thickness is <5 nm, N decreases sharply, and when the slab thickness is <10 nm, the phonon frequency \(\omega \) and slab thickness d changed significantly.
