Figure | Dynamic tuning of Bloch modes in the α-MoO₃ PoC/graphene device. a, Schematic of an α-MoO3 PoC/graphene device, consisting of a square periodically perforated α-MoO3/graphene heterostructure on a SiO2 (285 nm)/Si substrate. b Theoretically calculated band structure of the α-MoO3 PoC as a function of EF 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.
