Figure 2 (IMAGE) Institute for Basic Science Caption Diamonds of various morphologies as grown under different growth conditions. (a) Growth by using a liquid metal alloy of Ga/Ni/Fe/Si (77.75/11.00/11.00/0.25 at%) under methane/hydrogen (1/20 molar ratio). (b) Growth by using a liquid metal alloy of Ga/Ni/Fe/Si (77.50/11.00/11.00/0.50 at%) under methane/hydrogen (1/20 molar ratio). (c) Growth by using a liquid metal alloy of Ga/In/Ni/Fe/Si (38.88/38.87/7.33/14.67/0.25 at%) under methane/hydrogen (1/20 molar ratio). (d) Growth by using a liquid metal alloy of Ga/Ni/Fe/Si (77.75/11.00/11.00/0.25 at%) under methane/hydrogen (1/5 molar ratio).
