Abstract

In this paper, theoretical study on the surface phonon–polariton (SPP) modes of wurtzite (α-) structure indium nitride(InN)semi-infinite crystal is presented. Based on an anisotropy model, the surface polariton (SP) dispersion curve ofα-InNis simulated. The characteristics of this dispersion curve are discussed. The relevant experimental information by attenuated total reflection method is given. For comparison, the SP dispersion curve of cubic (β-) structure InN simulated based on isotropy model is also presented. Due to optical anisotropic, the SP dispersion curve ofα-InNexhibits an extra branch as well as an extra SPP mode as compared toα-InN. In addition, the SPP mode ofα-InNis found to be 4 cm-1smaller than that ofβ-InN.
