Spectroscopy of the Surface Polaritons in the CdXZn(1-X)P2Solid Solutions.
Here we report on the analysis of the effect of the doping of CdP2single crystals by ZnP2nanoclusters on the dispersion of the surface polaritons (SP). The ATR spectroscopic technique has been applied to excite the SP in the CdXZn(1-X)P2system. Analysis of the obtained spectra has shown that the doping of CdP2single crystals by ZnP2nanoclusters result in the position and the width of the dispersion branches of the SP. This effect is more pronounced in the low frequency dispersion branches. These SP branches are originated from phonons which correspond to the motion of the cation sublattice.
