Nanoscale crystal grain characterization via linear polarization X-ray ptychography

Chem Commun (Camb). 2020 Nov 3;56(87):13373-13376. doi: 10.1039/d0cc06101h.

Abstract

X-ray linear dichroism and X-ray birefringence microscopy are yet to be fully utilized as instruments in the microstructural characterization of crystalline materials. Here, we demonstrate analyser-free X-ray linear dichroism microscopy using spectroscopic hard X-ray ptychography. First experiments enabled a spectroscopic and microstructural characterisation of polycrystalline vanadium pentoxide on the nanoscale, outside of diffraction-contrast based methods.
