In this work, we report the growth process of single crystal diamond by doping boron (B) and hexagonal boron nitride (h-BN) in the system of Fe70Ni30 alloy catalyst and graphite. The doping of B and h-BN has signifi-cant effect on the growth condition and morphology of diamonds. The lowest growth pressure of h-BN doped diamond is 6.2Gpa and the crystals have a green strip morphology. This results indicates that B and h-BN have different effects on the diamond growth and have different ways to replace carbon atoms. We analyze the effect of doping B and N at-oms on the structure of diamond,and the chemical environment of B and N atoms in diamond by using X-ray diffrac-tion and photoelectron spectroscopy. The mechanism of B and N doped diamond is also demonstrated.
