Nearly lattice-matched ZnS x Se 1--x (0 x < 0.1) grown heteroepitaxially on (001) GaAs substrates was studied by Raman spectroscopy. We observed clearly Raman scattering on the plasmon-longitudinal optical (LO) phonon coupled mode at the GaAs side of the ZnS x Se 1--x -GaAs interfacial region under
