Abstract Here we analyze the propagation of Dyakonov surface waves(DSWs) at the interface between isotropic dielectric material and graphene-hBN hyperstructure (GhH) whose physical properties and optical topological transition regions can be controlled by varying the Fermi energy level of graphene sheets via electrostatic biasing. Various properties of the DSWs supported at the interface have been theoretically investigated, including the confinement factor and the polarization hybridization factor. By analyzing the electric-field intensity distribution of the DSWs excited by the linearly polarized dipole, it is found that the propagation direction of the DSWs can be controlled by the chemical potential of graphene. It is shown that the GhH supporting the DSWs with high wavenumber allows the enhanced amplitude of the spontaneous emission rate (SER) for one emitters to be flexibly controlled by the voltage applied to graphene.

石墨烯-hBN 超结构中的可调谐 Dyakonov 表面波

摘要 在这里，我们分析了 Dyakonov 表面波 (DSW) 在各向同性介电材料和石墨烯-hBN 超结构 (GhH) 之间的界面处的传播，其物理性质和光学拓扑跃迁区域可以通过静电改变石墨烯片的费米能级来控制。偏见。已从理论上研究了界面处支撑的 DSW 的各种特性，包括限制因子和极化杂化因子。通过分析线性极化偶极子激发的DSWs的电场强度分布，发现DSWs的传​​播方向可以通过石墨烯的化学势来控制。
