Particularly, the energy dispersion relationship of the conduction/valence band was explored in detail. At the {\\Gamma} point, the energy levels of both bands are significantly altered by applied uniaxial strain, which results in an evident change of band gap. In contrast, for the K vectors far away from {\\Gamma}, the variation of the conduction/valence band with strain is much reduced.
