Dispersions and mode patterns of the AlN and graphene-AlN. The dispersion curves (a) without and (b) with graphene. The E_x distributions corresponding to the color points (c) C (800 cm⁻¹) and (e) E (880 cm⁻¹) labeled in panel (a), and the E_x distributions corresponding to the color points (d) D (800 cm⁻¹) and (f) F (950 cm⁻¹) labeled in panel (b).
