Abstract: Abstract 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)… read more here.

Abstract: Quantum Hall states can be characterized by their chiral edge modes. Upon softening the edge potential, the edge has long been known to undergo spontaneous reconstruction driven by charging effects. In this Letter we demonstrate… read more here.
