Tip-Induced Etching and Vacancy Island Evolution on 2H-TaS<sub>2</sub> Revealed by STM

Tip-Induced Etching and Vacancy Island Evolution on 2H-TaS<sub>2</sub> Revealed by STM

Recent research on 2D materials using scanning probe microscopy reveals that the surface of transition metal dichalcogenides can be etched during the measurement via either a tunneling-field-driven or a scanning probe-driven process. The tip-induced manipulation of the surface structure and defects...
