Research Abstract |
Previously, we have discovered transformation from neutron-irradiated highly oriented pyrolytic graphite (HOPG) to amorphous diamond under shock compression. Here, we show the band gap energy of amorphous diamond is estimated to be 4 eV, which is similar to the value reported for the amorphous diamond synthesized from C60 fullerene by shock compression. In addition, we utilized HOPG foils irradiated with a neutron dose of about a half of the previous study, and found the transformation to the amorphous diamond. Also, we reported the synthesis of transparent graphitic tiles from carbon nanowalls by shock compression. It was suggested that the transparent tile is a mixture of amorphous diamond and superhard graphitic material.
