(color online) The shifts of Dirac point along ΓY for the germanene under 6% uniaxial strain applied along armchair (a) and zigzag (b) edges, respectively. The insets show the deviation of Dirac point referred to its position in the free-standing germanene as a function of the applied strain. Only the bands those cross to form Dirac point are shown for clarity. The notations of k-points Γ₁, T₁, and Y₁ are illustrated in Fig. 2(b).
