摘要：

The linear-chain approximation is used to calculate the spectrum of confined longitudinal-optical (LO) phonon frequencies in short-period strained-layer superlattices. The frequencies for confined LO-phonon modes are reported explicitly for the case of GaAs/GaP short-period strained-layer superlattices grown in the 〈001〉 direction. These results are compared with the few existing experimental measurements for such superlattices.
