Spectroscopy and dichroic mapping of the BN nanobamboo sample from spectro-ptychography. (a) B 1s absorption spectra from amplitude ptychography reconstruction. Spectra of vertical (green), horizontal (blue) BN nanobamboo and the lacy carbon support (red) measured with LH polarized light are shown. (b) Chemical and dichroic mapping from fits of the B 1s stack (42 images from 178 to 210 eV) to the spectra in (a) (same color coding). (c) N 1s absorption spectra from amplitude ptychography reconstruction. Spectra of vertical (green), horizontal (blue) BN nanobamboo and the lacy carbon support (red) measured with LH polarized light are shown. (d) Chemical and dichroic mapping from fits of the N 1s stack (43 images from 396 to 428 eV) to the spectra in (c) (same color coding).
