Combining the bond-order-length-strength corrected tight-binding (BOLS-TB) theory and the density functional theory (DFT) calculation, we clarified the energetic origin of the width-dependent band gap (Eg) expansion of the zigzag and armchair-edged antimonene nanoribbons (SbNRs) terminated by atomic...
