For the Integrated Quantum Photonics Group at Humboldt-Universität zu Berlin (led by Dr. Tim Schröder), I was allowed to illustrate the effect of nitrogen-vacancy defect centers in diamond nanostructures.

nanopillar Schematic sketch of an NV incorporated in a nanopillar. Green laser irradiation causes ionization of present surface and bulk defects, i.e. charges are released and move within the lattice, for example, to other defects that act as charge traps. This dynamic induces fluctuations of the electrostatic environment of the NV and leads to spectral diffusion of the NV ZPL.
