Spatially Correlated Microstructure and Superconductivity in Polycrystalline Boron-Doped Diamond
F. Dahlem, P. Achatz, O.A. Williams, D. Araujo, E. Bustarret, H. CourtoisScanning tunneling spectroscopies are performed below 100 mK on polycrystalline boron-doped diamond films characterized by transmission electron microscopy and transport measurements. We demonstrate a strong correlation between the local superconductivity strength and the granular structure of the films. The study of the spectral shape, amplitude, and temperature dependence of the superconductivity gap enables us to differentiate intrinsically superconducting grains that follow the BCS model, from grains showing a different behavior involving the superconducting proximity effect.
