Dependence of the superconducting transition temperature on the doping level in single crystalline diamond films

Etienne Bustarret, Jozef Kacmarcik, Christophe Marcenat +4

Homoepitaxial diamond layers doped with boron in the 10^20-10^21 /cm3 range are shown to be type II superconductors with sharp transitions (~0.2K) at temperatures increasing from 0…
