### Abstract

The effects of temperature T, average number of optical phonons N, the phonon frequency $$\omega$$ ω 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 $$\omega$$ ω increases with increasing temperature T, but the average number of optical phonons N and phonon frequency $$\omega$$ ω 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 $$\omega$$ ω and slab thickness d changed significantly.
