Abstract
The relationship of an asymmetrical Gaussian potential among average number of optical phonons N, temperature T and slab thickness d, in a polar slab was investigated using linear combination operator and unitary transformation methods. The results showed that the phonon frequency [Formula: see text] increases with increased temperature T, but the average number of optical phonons N and temperature T decreases with increased slab thickness d.
