Query: Mechanical manipulation and exfoliation of boron nitride flakes by
  micro-plowing with an AFM tip   We demonstrate a simple method to manipulate and exfoliate thick hexagonal
boron nitride (h-BN) flakes using an atomic force microscope (AFM) cantilever
and tip mounted to a micromanipulator stage. Thick flakes of tens to hundreds
of nanometers can be thinned down to large area, few-layer and monolayer
flakes. We characterize the resulting thinned-down flakes using AFM and Raman
spectroscopy. This technique is extendable to other two dimensional, van der
Waals materials.
