Electron Tomography of Electromagnetic Fields, Potentials and Sources

Project: Research

Project Description

This project adds a new dimension to conventional scalar tomography, by developing and implementing vector field electron tomography on a transmission electron microscope. Non-interferometric phase retrieval methods will allow the reconstruction of three-dimensional (3D) electromagnetic fields, potentials and sources, at a spatial resolution approaching the nanoscale. The proposed methodology is flexible, robust and quantitative, and will find widespread applications to elucidating the 3D electromagnetic structure of materials, such as: current distributions in superconductors, field distributions in semiconductors and magnetic fields in patterned nanomagnets, magnetotactic bacteria, or even novel magnetic proteins.
