摘要：

The SiC₇ siligraphene (g-SiC₇) is a novel 2D nanomaterial with graphene-like structure. Based on theoretical calculations, we have systematically investigated the structure, stability, electronic and optical properties of g-SiC₇ siligraphene. The calculated results reveal that g-SiC₇ siligraphene is a semiconductor with a direct band gap of 1.13 eV, which can be easily tuned by applying biaxial strain or perpendicular electric field. Such a g-SiC₇ siligraphene shows superior optical absorbance to sunlight and is better than that of g-SiC₂ siligraphene and single-layer black phosphorus (phosphorene) in near infrared and visible photon ranges, thus holding great potential for photovoltaics applications as a light donor material.
