文献中
The structural and electronic properties  are investigated using the first-principles pseudopotential method as implemented in the ABINIT code. The Brillouin zones are sampled with a 10 × 1 × 8 Monkhorst-Pack k mesh. The cutoff energy for the plane-wave expansion is set to be 800 eV. For the structural relaxation, the exchange-correlation energy is in the form of Perdew-Burke-Ernzerhof (PBE) with generalized gradient approximation (GGA). Both the geometries and atomic positions are fully relaxed until the force acting on each atom is less than 0 .5 × 10−3eV/˚A. In the calculations of the electronic structures, the Tran-Blaha modified Becke-Johnson (TB-mBJ) potential [25 ]isused, which can reproduce accurate band gaps for many semi-conductors.
我的计算:
用castep
The Brillouin zones are sampled with a 8 × 2× 5 Monkhorst-Pack k mesh. The cutoff energy for the plane-wave expansion is set to be 180 eV. For the structural relaxation, the exchange-correlation energy is in the form of Perdew-Burke-Ernzerhof (PBE) with generalized gradient approximation (GGA). Both the geometries and atomic positions are fully relaxed until the force acting on each atom is less than 0.03eV/˚A.

至少你得说明你是什么软件,设置什么,
文献又是如何(说不清的,直接给出文献名称)
才能判断合不合理.

你算的带隙不一致,但是相当于这里的形状基本上差不多。 因为你把横坐标变成比较大的就行
