Nanoscale sculpting of hBN with an electron beam and characterization via PL microscopy and ionic transport
Rachael N. KeneippUniversity of Pennsylvania, Philadelphia, Pennsylvania, USA _______________________________________ Creating sub- to few-nanometer defects and nanopores in hexagonal boron nitride (hBN) opens opportunities for engineering quantum emitters and for nanofluidic and sensing applications. Using the electron beam in the aberration-corrected scanning transmission electron microscope, we demonstrate modification, thinning, and drilling of features in few-layer hBN…
