Eu2O3 thin films were epitaxially grown on (001)LaAlO3 (LAO) substrates using a polymer-assisted deposition technique. Microstructural studies by x-ray diffraction and transmission electron microscopy show that the films are epitaxial with an orientational relationship of (001)Eu2O3¦¦(001)LAO and [1&1macr;0]Eu2O3¦¦[100]LAO. We have found a systematic change in the out-of-plane lattice parameter of Eu2O3 (a⊥) with the annealing temperature, which is believed to be from different strain effects.

    The dc electric-field (E) dependence of the dielectric constant ([variant_greek_epsilon]) in PbZr0.52Ti0.48O3 (PZT) thin films has been studied at cryogenic temperatures in the dc electric-field range of 0–820 kV/cm. Significant suppression of [variant_greek_epsilon] is observed by an...

    We report on the diagnostic of ultrafast pulses by frequency-resolved optical gating (FROG) based on strong third-harmonic generation (THG) in amorphous organic thin films. The high THG conversion efficiency of these films allows for the characterization of sub-nanojoule short pulses emitting at...

    Films fabricated using the glancing angle deposition technique are subject to significant variations in several important film parameters across a sample due to geometric conditions that are not uniform across the substrate. This paper presents a method to quantify the non-uniformities in these...

    Single-crystal Nb-doped Pb(Zr,Ti)O3 (PNZT) films were grown on electric conducting single-crystal Nb-doped SrTiO3 (Nb:STO) wafers by a sol-gel method. Although the films were of the same composition and prepared under the same condition, different crystal phases with corresponding preferential...

    The physical origin of quantum-size effects (QSEs) and its impact on the decay length of electrons in Pb thin films are studied by first-principles calculations. We show that QSE is not only size but also wavevector dependent: being maximum at [formula] due to strong interlayer coupling between...
