摘要：

We report Raman spectra of cubic Zn1-xCdxS grown by metalorganic vapor-phase epitaxy and metalorganic molecular-beam epitaxy on (001) GaAs substrates. Two longitudinal-optical (LO) modes and one transverse-optical mode are observed, and their behavior is similar to that of the one-mode type. However, the signal intensity of the lower-frequency LO phonon is strong compared with that in hexagonal Zn1-xCdxS, which exhibits a typical one-mode behavior. We also observe two additional peaks that are tentatively attributed to disorder-activated modes.
