Figure 2: (a) Top and side view of the crystal structures of ZrBr monolayers. (b) Phonon dispersions. (c) Band structure without SOC, with SOC and obtained from MLWFs indicated by gray solid line, blue solid line and red dashed line, respectively. Insets show the zoom-in view of the orbital resolved band structure near the Γ point. (d)Band structure of the1Dribbon with nontrivial edge states highlighted in red.
