Dynamic tuning of Bloch modes in anisotropic phonon polaritonic crystals
Figure | Dynamic tuning of Bloch modes in the α-MoO₃ PoC/graphene device. a , Schematic of an α-MoO 3 PoC/graphene device, consisting of a square periodically perforated α-MoO 3 /graphene heterostructure on a SiO 2 (285 nm)/Si substrate. b Theoretically calculated band structure of the α-MoO 3 PoC as a function of E F at a fixed frequency of 931 cm −1 . The yellow dashed lines indicate the free space light cone. Inset: the first Brillouin zone of the square-type PoC. Cre
