Towards better superconductors by periodic nanopatterning

Bachelor thesis | Natuurkunde (BSc)

We used modern clean room technologies to produce thin nanopatterned superconductors in an aim to increase their critical temperature. These experiments are based on existing simulations which indicate that a large change in the electron-phonon coupling parameter lambda is attainable. The simulations were explored in an effort to find an optimal hole geometry and an attempt was made to extend them to a hexagonal lattice of atoms. We obtained ~50nm circular holes spaced 120nm on both MoGe and NbSe2 while also producing contacts to measure these small structures.
