From: Uniaxial strain-induced mechanical and electronic property modulation of silicene
Band structures and shift directions of Dirac points of silicene. Band structures of silicene: (a) without strain, under AC strains of (b) 12.4% and (c) 15.7%, and under ZZ strains of (d) 7.5%, and (e) 13.0%, respectively. The red dashed line denotes the Fermi level. Insets: magnified portion of band structures near the Dirac point. (f) Shift directions of Dirac points of silicene under small tensile strains.
