Research Abstract

In this study, we adopted the new high-pressure synthetic technique, which carbonate is used as diamond producing catalysts, and achieved to prepare the boron doped superconducting diamond crystal under lower P-T condition reported before. Our sample showed maximum superconducting transition temperature (T_c) at 10.3 K, which is the highest T_c ever reported about high-pressure synthetic diamond.
