Scanning Probe Nanopatterning and Layer‐by‐Layer Thinning of Black Phosphorus

Nanopatterning and layer‐by‐layer thinning of black phosphorus is demonstrated with conductive atomic‐force‐microscope anodic oxidation. The liquid‐phase patterning byproduct is readily removed by water rinsing. An alternating‐current bias enables direct nanopatterning and thinning on insulating sub...

Beschreibung
Zusammenfassung:	Nanopatterning and layer‐by‐layer thinning of black phosphorus is demonstrated with conductive atomic‐force‐microscope anodic oxidation. The liquid‐phase patterning byproduct is readily removed by water rinsing. An alternating‐current bias enables direct nanopatterning and thinning on insulating substrates such as SiO2/Si. Field‐effect transistors with patterned channels show significant improvements in current modulation by up to a factor of 50.
