| Outline of Final Research Achievements |
We designed a host-guest system which will incorporates hydrogen atoms in the Rydberg state into its interstitial spaces and tried to apply it to an innovative battery system having huge electromotive force due to its high energy excited state. The crystal lattice of a metallic perovskite, Mn3Cu1-x GeｘN was greatly and irreversibly expanded after the DC hydrogen plasma treatment and its origin is suggested to be hydride ions (H-) incorporated into the interstitial space surrounded by Mn-Cu(Ge) octahedral coordination cages. From the result of optical and electrical characterizations, it was concluded that this Mn 3 Cu 1-x GexN system showed a metal to a wide gap semiconductor transition accompanied by the huge lattice expansion due to the interstitial hydride ions. . Unfortunately we cannot confirm the Rydberg state of this system even under the deep UV light irradiation.
