Individual Titanate Nanoribbons Studied by 3D-Resolved Polarization Dependent X‑ray Absorption Spectra Measured with Scanning Transmission X‑ray Microscopy

Polarization dependent X-ray absorption spectroscopy (XAS) is a powerful probe of the anisotropic electronic structure of bulk single crystals, but its application to nanostructured samples is challenging. Here we describe a method for obtaining linearly polarized XAS spectra along three orthogonal axes of an individual nano-object using scanning transmission X-ray microscopy (STXM). The technique is applied to a single sodium titanate …
