WebOct 8, 2024 · Real space honeycomb lattice: The honeycomb lattice of graphene show in Fig. 2(a) is not a Bravais lattice. Instead, it can be viewed as bipartite lattice composed of two interpenetrating triangular sublattices. Thus, such lattice with a basis contains two identical carbon atoms per primitive unit cell. WebSep 1, 2024 · The triple-site honeycomb lattice unit cell can achieve topological phase transitions in three ways, which are changing the position or size of the cylinders, and rotating the cylinders. • We design a frequency-selective beam splitter, by changing the rotation angle of the dielectric rods. Abstract
