Organic Molecular Dynamics and Charge-carrier Lifetime in Lead Iodide Perovskite MAPbI
A. Koda, H. Okabe, M. Hiraishi +4
The long charge carrier lifetime of the hybrid organic-inorganic perovskites (HOIPs) is the key for their remarkable performance as a solar cell material. The microscopic mechanism…
Anomalous diamagnetism of electride electrons in transition metal silicides
M. Hiraishi, K. M. Kojima, H. Okabe +5
Intermetallic silicide compounds, LaScSi and YSi, known for being hydrogen (H) storage materials, are drawing attention as candidates for electrides in which anions are sub…
Electronic structure of interstitial hydrogen in In-Ga-Zn-O semiconductor simulated by muon
K. M. Kojima, M. Hiraishi, H. Okabe +7
We report on the local electronic structure of interstitial muon (Mu) as pseudo-hydrogen in In-Ga-Zn oxide (IGZO) semiconductor studied by muon spin rotation/relaxation (SR) exp…
Local Electronic Structure of Interstitial Hydrogen in Iron Disulfide
H. Okabe, M. Hiraishi, S. Takeshita +3
The electronic structure of interstitial hydrogen in a compound semiconductor FeS (naturally -type) is inferred from a muon study. An implanted muon (Mu, a pseudo-hydrogen)…
Electronic correlation in the quasi-two-dimensional electride YC
M. Hiraishi, K. M. Kojima, I. Yamauchi +10
Magnetic properties of the electride compound YC were investigated by muon spin rotation and magnetic susceptibility on two samples with different form (poly- and single-crysta…
Cage Electron-Hydroxyl Complex State as Electron Donor in Mayenite
M. Hiraishi, K. M. Kojima, M. Miyazaki +6
It is inferred from the chemical shift of muon spin rotation (SR) spectra that muons implanted in pristine (fully oxidized) mayenite, [CaAlO[$\square_…
