Query: Direct Imaging of Charge Redistribution due to Bonding at Atomic
  Resolution via Electron Ptychography   Phase imaging in electron microscopy is sensitive to the local potential
including charge redistribution from bonding. We demonstrate that electron
ptychography provides the necessary sensitivity to detect this subtle effect by
directly imaging the charge redistribution in single layer boron nitride.
Residual aberrations can be measured and corrected post-collection, and
simultaneous atomic number contrast imaging provides unambiguous sub-lattice
identification. Density functional theory calculations confirm the detection of
charge redistribution.
