Nanofabrication of 3D topological materials
Using state-of-the-art 3D printing techniques based on focused electron and ion beams, we fabricate 3D topological materials for applications in nanoelectronics.
By creating complex 3D geometries, we investigate new effects emerging result of the coupling between geometry and the order parameter of the system (e.g. the magnetization).
We have for instance reported how topological stray fields and topological spin states can be locally generated by exploiting chiral nanoscale geometries.
