The electronic properties of low-dimensional nanomaterials have attracted intense attention. The electronic properties of SnCH3 monolayer nanosheets and nanoribbons hydrogenated along the zigzag and armchair borders are investigated with density functional theory. Energy gap is an important aspect of electronic properties. The elastic strain and width are introduced to research the variation of energy gap. The computation results show that the energy gap can be easily tuned under strain and width. Moreover, the band gap decreases when increasing the stretch strain or decreasing the compress strain. Therefore, the SnCH3 nanomaterials are anticipated to play an important role in strain sensors, electronics, and optical electronics.
