Strongly Anharmonic Organic Cation Vibrations in Hybrid Lead Halide Perovskite CH3NH3PbI3 on Electronic Ground State
Kunie Ishioka, Terumasa Tadano, Masatoshi Yanagida +2
Ultrafast vibrational dynamics of inorganic-organic hybrid lead halide perovskite CH3NH3PbI$ in the room-temperature tetragonal phase is investigated under moderate photoexcitation…
Direct Observation of Sub-picosecond Hole Injection from Lead Halide Perovskite by Differential Transient Transmission Spectroscopy
Kunie Ishioka, Bobby G. Barker, Masatoshi Yanagida +2
Efficient charge separation at the interfaces between the perovskite and with the carrier transport layers is crucial for perovskite solar cells to achieve high power conversion ef…
Polar Antiferromagnets Produced with Orbital-Order
Naoki Ogawa, Yasushi Ogimoto, Yoshiaki Ida +3
Polar magnetic states are realized in pseudocubic manganite thin films fabricated on high-index substrates, in which a Jahn-Teller (JT) distortion remains an active variable. Sever…
Nonlinear Optical Response of SrTiO3/LaAlO3 Superlattices
N. Ogawa, K. Miyano, M. Hosoda +4
The electronic symmetry of the SrTiO3/LaAlO3 interface was investigated by optical second harmonic generation, using superlattices with varying periodicity to study the evolution o…
Structural study on Pr0.55(Ca[1-y]Sr[y])0.45MnO3 thin films on perovskite (011) substrate
Yusuke Wakabayashi, Naoko Takubo, Kenjiro Miyano +1
Structural study on the photo-switching system Pr{0.55}(Ca{1-y}Sr y){0.45}MnO3 thin films on perovskite (011) substrate has been made with synchrotron radiation diffraction experim…
Relative contributions of lattice distortion and orbital ordering to resonant x-ray scattering in manganites
M. Nakamura, M. Izumi, N. Ogawa +3
We investigated the origin of the energy splitting observed in the resonant x-ray scattering (RXS) in manganites. Using thin film samples with controlled lattice parameters and orb…
