The researchers obtained the image using a technique called electron ptychography. It involves shooting a beam of electrons, about a billion of them per second, at a target material. The beam moves infinitesimally as the electrons are fired, so they hit the sample from slightly different angles each time—sometimes they pass through cleanly,
Sounds like x-ray diffraction, but with electrons.

This technique uses higher energy electrons than electron diffraction measurements and that translates to smaller wavelength. It means you can "image" at atomic resolution.
