摘      要：We present a theoretical study on the composition dependence of the surface phonon polariton （SPP） mode in wurtzite structure α-InxGa1-xN ternary alloy over the whole composition range. The SPP modes are obtained by the theoretical simulations by means of an anisotropy model. The results reveal that the SPP mode of α-InxGa1-xN semiconductors exhibits one-mode behaviour. From these data, composition dependence of the SPP mode with bowing parameter of-28.9 cm^-1 is theoretically obtained.
