Dual nature of localized phase defects in the In/Si(111) atomic wire array: impurities and short topological solitons
Abdus Samad Razzaq, Sun Kyu Song, Tae-Hwan Kim +2
We demonstrate the existence of atomically-sized topological solitons in a quasi one-dimensional charge density wave system: indium atomic wires on Si(111). Performing joint scanni…
