Fig. 3: The band structures and corner states of Ta2Ni3Te5 monolayer.
From: Quadrupole topological insulators in Ta2M3Te5 (M = Ni, Pd) monolayers
The orbital-resolved band structures of a \({d}_{{z}^{2}}\) orbitals of Ta atoms, b dxz orbitals of NiA atoms, and c px orbitals of Te atoms. d The comparison between band structures of maximally localized Wannier functions and DFT results. e (01)-edge states around Γ. f The charge distribution of four corner states. The insert shows the energy spectrum of the tight-binding model with open boundaries in x and y directions.
