Fermi surface topology of deuterium-doped vanadium: Compton scattering study
The deuteration-induced effect on the Fermi surface (FS) topology of V was investigated by the synchrotron-based Compton scattering technique with 115 keV X-rays. The three-dimensional occupation number density (OND) of alpha -VD sub(0.64 single crystal and V single crystal was reconstructed by the...

| description | The deuteration-induced effect on the Fermi surface (FS) topology of V was investigated by the synchrotron-based Compton scattering technique with 115 keV X-rays. The three-dimensional occupation number density (OND) of alpha -VD sub(0.64 single crystal and V single crystal was reconstructed by the directional Compton profiles along 13-18 directions. The observed OND shows that the FS topology of alpha -VD) sub(0).64.differs from that of V at Gamma , N, and H points in the crystal momentum space, which are hole position for V. This indicates that electrons that originate from deuterium modify the upper part of the host metal d bands (3rd and 4th bands) at the Fermi level E sub(F, and forms the metal-hydrogen bonding states with the lower part of the host metal d band (1st band).) |
