| Outline of Final Research Achievements |
In order to understand the novel pressure-induced interaction between hydrogen and carbon π electron system having graphite structure, few layer graphene and hexagonal boron nitride were pressurized in the helium or hydrogen gas and their pressure-induced structural-change were carried out in situ. The electronic structure has the large difference between graphite and hexagonal boron nitride, however, both structures were influenced by hydrogen under pressure up to 3 GPa.
We also tried the DFT calculations of the structures of graphite and hexagonal boron nitride pressurized under high pressure hydrogen atmosphere. The results showed that both did not show hydrogen stage or slightly small amount of hydrogen was accommodated in the inter layers.
