Abstract
Measuring the three-dimensional (3D) distribution of chemistry in nanoscale matter is a longstanding challenge. This paper presents fused multi-modal electron tomography, achieving high-resolution 3D chemical mapping for various nanomaterials. Multi-modal data fusion links elastic and inelastic scattering signals, enabling sub-nanometer 3D resolution of chemistry even at low electron doses. The technique is validated across multiple material systems.
