Synthesis and characterization of boron and nitrogen co-doped diamond crystals under high pressure and high temperature conditions

Abstract

In this study, diamond crystals co-doped with boron and nitrogen were synthesized <italic>via</italic> a temperature gradient method at 5.3–5.8 GPa and 1300–1550 °C by adding B and N dopants to a system of carbon and an Fe-based solvent catalyst.
