Highly hydrogen-sensitive thermal desorption spectroscopy system for quantitative analysis of low hydrogen concentration (~1 x 10^16 atoms/cm3) in thin-film samples
Taku Hanna, Hidenori Hiramatsu, Isao Sakaguchi +1
We developed a highly hydrogen-sensitive thermal desorption spectroscopy (HHS-TDS) system to detect and quantitatively analyze low hydrogen concentrations in thin films. The system…
Superconductivity in 1111-type CaFeAsF1-xHx induced by selective hydrogen elimination
Taku Hanna Yoshinori Muraba Satoru Matsuishi, Hideo Hosono
The difference in thermal stability of F- and H- in 1111-type iron based superconductors, allows selective hydrogen elimination from non-superconductive CaFeAsF0.8H0.2 by thermal a…
Two-dome structure in electron-doped iron arsenide superconductors
Soshi Iimura, Satoru Matuishi, Hikaru Sato +6
Iron arsenide superconductors based on the material LaFeAsO1-xFx are characterized by a two-dimensional Fermi surface (FS) consisting of hole and electron pockets yielding structur…
Hydrogen in layered iron arsenide: indirect electron doping to induce superconductivity
Taku Hanna, Yoshinori Muraba, Satoru Matsuishi +3
Utilizing the high stability of calcium and rare earth hydrides, CaFeAsF1-xHx (x = 0.0-1.0) and SmFeAsO1-xHx (x = 0.0-0.47) have been first synthesized using high pressure to form…
