Image shows the “stripes” (the alternating yellow and blue regions) of electronic charge alignment found in a ferroelectric thin film. It was reconstructed from a series of x-ray diffraction patterns (like those shown at the bottom of the image). The positions of the diffraction measurements are indicated by the open dots. The bright spot shows the shape and intensity of the x-ray nano-beam footprint at a single point.
Imaging Nanoscale Polarization in Ferroelectrics with Coherent X-Rays

Seeing the fine-scale properties of materials relevant to nanotechnology is a prominent challenge that currently can be met only under ideal conditions.
