(a) Electron band structure of A(3)-GDYNR under different stress (− 1.5 to 3.GPa); (b) electron band structure of Z(3)-GDYNR under different stress (− 3.5 to 7.5 GPa); (c, d) A(3)-GDYNR and Z(3)-GDYNR band gap changes under different stress (green line), cell parameter a0 changes with different stress (red line); (e, f) plots of the effective mass of A(3)-GDYNR and Z(3)-GDYNR with different stress applied perpendicular to the plane.
