Many studies on superconductivity of boron-doped diamond (BDD) have been done, and it is well known that the superconducting transition temperature Tc of BDD films depend on the boron concentration and the growth direction. Uniaxial like pressure along (111) direction was applied on boron-doped (111) diamond films synthesized by CVD method using a diamond-anvil cell (DAC) up to 18.5 GPa. The Tc was decreased as previous report, however the changing rate is smaller than other experiments with hydrostatic pressures and a theoretical prediction.
