Tomography to determine crystal structure in 3d

Project Goals and Description:
Strain plays a critical role in all realms of solid-state materials technology, from batteries to semiconductors to metals. Full three-dimensional strain profiles around simple strained objects such as dislocations and at interfaces have been simulated, but never fully characterized on atomic length scales. This proposed work will develop methods to use scanning nanobeam electron diffraction algorithms for three-dimensional data reconstructions to map strain in three dimensions for various nanostructures. The work to develop these algorithms in MATLAB in this project will lead to the development and validation of a general technique to enable 3d strain mapping of many materials.
