Abstract

The superconducting transition temperatures (T_C) of (1 1 1) and (0 0 1) boron-doped diamond films deposited by microwave plasma assisted chemical vapor deposition (MPCVD) are investigated in the wide boron concentration range of 1 × 10²⁰ - 1 × 10²² cm^-3. The critical boron concentrations of superconductor to insulator transition in (1 1 1) and (0 0 1) films are 3 × 10²⁰ cm^-3. T_C in (1 1 1) films does not have the tendency to saturate up to 1 × 10²² cm^-3, while T_C in (0 0 1) films saturates.
