The surface excitations are investigated in the three‐medium system of an ionic crystal, vacuum, and a type II semiconductor superlattice by making use of Maxwell's equations. The dispersion relations for the plasmon–optical phonon coupled modes are obtained on the interface between these two materials. The surface modes are discussed in detail in both, the high‐ and low‐frequency regions for the weak coupling limit.
