Fig. 3From: Strain Tunable Bandgap and High Carrier Mobility in SiAs and SiAs2 Monolayers from First-Principles StudiesBand structures of monolayer SiAs and SiAs2 calculated by PBE and HSE06. The electronic orbital decomposition of band structures of monolayers SiAs and SiAs2 are represented as a and b, respectively. The red dots denote s orbital, while blue, yellow, and green are px,py, and pz, respectively. The Fermi level is set as zero and indicated with a dot lineBack to article page
