Abstract

It is important for a new superconducting device application to demonstrate Josephson effect by homoepitaxial all diamond junction. Using only CVD diamond, we have fabricated stacked SNS (superconductor-normal conductor superconductor) Josephson junction where normal state diamond film is sandwiched by superconducting diamond films. The current-voltage (I-V) characteristics of the junction showed clear Josephson properties at 2 K.
