    Raman scattering studies of the lattice dynamics in layered MoS2

    We report non-resonant and resonant Raman scattering studies of layered MoS2. Owing to its reduced dimensionality, few layered MoS2 is more sensitive to the difference between inter- and intra-layer coupling, whi...

    Electroporation markedly improves Slee** Beauty transposon-induced tumorigenesis in mice

    The Slee** Beauty (SB) transposon system is an important tool for genetic studies. It is used to insert a gene of interest into the host chromosome, thus enabling permanent gene expression. However, this sys...

    Local current–voltage behaviors of preferentially and randomly textured Cu(In,Ga)Se2 thin films investigated by conductive atomic force microscopy

    Electrical transport properties on polycrystalline Cu(In,Ga)Se2 (CIGS) (Ga/(In+Ga) ≈35%) thin films were examined by conductive atomic force microscopy. The CIGS thin films with a (112) preferential or random tex...

    High Rate in situ YBa2Cu3O7 Film Growth Assisted by Liquid Phase

    High-rate (10 nm/s) in situ YBa2Cu3O7 (YBCO) film growth was demonstrated by molecular beam epitaxy with electron beam co-evaporation at a system pressure of approximately 5 × 10-5 Torr. To explain the phase stab...

    Neutron-diffraction studies of YMnO3

    We have made thermal expansion and neutron-diffraction studies of YMnO3, and found that our bulk measurements showed anomalous behavior at TN=80 K. The analysis of the neutron-diffraction data shows that the magn...

    Magnetic structure studies of ErMnO3

    ErMnO3 forms in a hexagonal structure with P63cm space group. Our neutron-diffraction studies from room temperature to 10 K show that ErMnO3 undergoes an antiferromagnetic transition at around 80 K, consistent wi...

    Structural and ferroelectric properties of Bi4Ti3O12 thin films on IrO2 prepared by rf magnetron sputtering

    Bismuth titanate, Bi4Ti3O12, thin films were grown on IrO2/SiO2/Si substrates by radio-frequency magnetron sputtering. Crystallinity and microstructure of the films were characterized over a wide range of oxygen ...

    Epitaxial Sr-Bi-Ta Oxide Films of Cubic Fluorite-Like Structure

    Epitaxial Sr-Bi-Ta oxide films of a cubic fluorite-like structure were grown by pulsed laser deposition. As the laser fluence increased, the lattice constant decreased. It was revealed that the Ta ion concentr...

    Lanthanum-substituted bismuth titanate for use in non-volatile memories

    Non-volatile memory devices are so named because they retain information when power is interrupted; thus they are important computer components. In this context, there has been considerable recent interest1,2 in ...

    Effects of Interfacial States on Asymmetric Polarization Switchings of Epitaxial Bi4Ti3O12 Thin Films

    Epitaxial Bi4Ti3O12 (BTO) films with La0.5Sr0.5CoO3 (LSCO) or Pt bottom electrodes were grown on MgO(001) substrates by pulsed laser deposition. Surprisingly, a symmetric Pt/BTO/Pt capacitor showed a highly asymm...
