Nanostructures made from superconducting boron doped diamond

Abstract

We report on the transport properties of nanostructures made from boron-doped superconducting diamond. Starting from nanocrystalline superconducting boron-doped diamond thin films, grown by Chemical Vapor Deposition, we pattern by electron-beam lithography devices with dimensions in the nanometer range. We show that even for such small devices, the superconducting properties of the material are well preserved: for wires of width less than $100nm$, we measure critical temperatures in the Kelvin range and critical field in the Tesla range.
