| Outline of Final Research Achievements |
Ti-Ni-Si amorphous alloys that have nano-porus structures generated by dealloying and anodizing are expected to be a new material for capacitors or electricity storage devices. To clarify local structures and electronic properties in the nano-porus Ti-Ni-Si amorphous alloys, local structures around Ti-Ti/Ti-Ni/Ni-Ni atoms in Si host and interactions between them are investigated by using the first principles calculation. The structures of nano-porus Ti-Si alloys obtained by removing Ni atoms from a precursor Ti-Ni-Si alloy are also investigated as a simulation of the dealloying process.
