| Outline of Final Research Achievements |
For the future application of electronic materials, we investigates the conductivity of nano-polycrystalline diamond synthesized by high-pressure and high-temperature technique. Also to control its conductivity, we tried impurity doping on the diamond. We observed semiconducting conductivity for the nano-polycrystalline diamond at temperatures higher than 400 degree C. Also, optical characteristics were investigated on that. When nano-polycrystalline diamond was synthesized with InP, it seemed to be introduced into the crystal. We prepared single crystalline diamond and put P ion implantation on its surface. After applying high pressure and high temperature for the diamond, unexpected pyramidal microstructure was formed on the surface.
