Journal ArticleDOI
Lead-Free Highly Efficient Blue-Emitting Cs3Cu2I5 with 0D Electronic Structure
TL;DR: New halide materials that meet the requirements of: (i) nontoxicity, (ii) high PLQY, and (iii) ease of fabrication of thin films via the solution process are explored.
Journal ArticleDOI
Two-dome structure in electron-doped iron arsenide superconductors
Soshi Iimura,Satoru Matsuishi,Hikaru Sato,Taku Hanna,Yoshinori Muraba,Sung Wng Kim,Sung Wng Kim,Jungeun Kim,Masaki Takata,Hideo Hosono +9 more
TL;DR: Density functional theory calculations reveal that the three Fe 3d bands (xy, yz and zx) become degenerate at x=0.36, whereas the FS nesting is weakened monotonically with x, implying that the band degeneracy has an important role to induce high T(c).
Journal ArticleDOI
Discovery of earth-abundant nitride semiconductors by computational screening and high-pressure synthesis
Yoyo Hinuma,Taisuke Hatakeyama,Yu Kumagai,Lee A. Burton,Hikaru Sato,Yoshinori Muraba,Soshi Iimura,Hidenori Hiramatsu,Isao Tanaka,Isao Tanaka,Hideo Hosono,Fumiyasu Oba +11 more
TL;DR: The screening of ternary zinc nitride semiconductors using first-principles calculations of electronic structure, stability and dopability identifies as-yet-unreported CaZn2N2 that has earth-abundant components, smaller carrier effective masses than gallium nitride and a tunable direct bandgap suited for light emission and harvesting.
Journal ArticleDOI
Formation and Characterization of Hydrogen Boride Sheets Derived from MgB2 by Cation Exchange.

TL;DR: The experimental realization of 2D hydrogen boride sheets with an empirical formula of H1B1 is reported, produced by exfoliation and complete ion-exchange between protons and magnesium cations in magnesium diboride (MgB2) with an average yield of 42.3% at room temperature.

TL;DR: The superconductivity in iron pnictide compounds occurs near a magnetic phase and magnetic spin fluctuations are prime candidates for the superconducting pairing mechanism as mentioned in this paper, and it has been shown that a second magnetic phase, next to another super-conducting phase, is found at higher doping levels.
