Nanostructured materials at the atomic scale: determining the composition using quantitative analytical electron tomography.

During my PhD research, we developed and performed electron tomography experiments in order to measure the positions of the atoms in a nanostructure. However, the burning questions in the field of nanoscience can no longer be solved by only determining the atomic structure. Nowadays, it becomes crucial to measure the chemical nature and even the oxidation state of each individualatom in a nanostructure as well. Therefore, the aim of this project is to push the limits of electron tomography beyond the state-of-the-art and to provide a complete 3D quantitative chemical characterisation of complex hetero-nanosystems down to the atomic scale.
