Description

Pelz leads a large team that solves tiny structures with a new electron method, in work from twenty twenty-three. A strong electron scope can show the atoms in a sample. But the old way to build a three dimensional view fails with mixed nano samples that hold light parts. Such mixed samples were a blind spot.

Their method, ptychographic atomic electron tomography, used tens of millions of diffraction patterns. It rebuilt an atomic level tilt series of a carbon nanotube. That tube held a complex sandwich of zirconium and tellurium. Class averaging and fine tracking of the atomic peaks made the view sharp. The step extends atomic imaging to complex, mixed nano samples that older methods could not resolve in three dimensions.
