The electric-field (E-field) controlled exchange bias (EB) in a Co90Fe10/BiFeO3 (BFO)/SrRuO3/PMN-PT heterostructure has been investigated under different tensile strain states. The in-plane tensile strain of the BFO film is changed from +0.52% to +0.43% as a result of external E-field applied to the PMN-PT substrate. An obvious change of EB by the control of non-volatile strain has been observe...

The photovoltaic performance of a quantum dot (QD)-sensitized solar cell consisting of CdS/CdSe/ZnS QDs loaded onto the surface of the three-dimensional (3D) flower-like TiO2 structure grown on an array (1D) of TiO2 nanorods (FTiR) is studied. The flower-like structure on the rod-shaped titania was synthesized using a double-step hydrothermal process. The FTiR array exhibited a 3D/1D composite ...

We investigate complex PT and non-PT-symmetric forms of the generalized WoodsSaxon potential. We also look for exact solutions of the Schrödinger equation for the PT and/or non-PT-symmetric potentials of the kind mentioned above. Nikiforov-Uvarov method is used to obtain their energy eigenvalues and associated eigenfunctions. PACS:03.65.Fd, 03.65.Ge, 02.30.Gp

We discuss eigenvalue problems of the form −w+Pw = λw with complex polynomial potential P (z) = tzd+. . ., where t is a parameter, with zero boundary conditions at infinity on two rays in the complex plane. In the first part of the paper we give sufficient conditions for continuity of the spectrum at t = 0. In the second part we apply these results to the study of topology and geometry of the r...

Here we proposed a novel architectural design of a ternary MnO2-based electrode - a hierarchical Co3O4@Pt@MnO2 core-shell-shell structure, where the complemental features of the three key components (a well-defined Co3O4 nanowire array on the conductive Ti substrate, an ultrathin layer of small Pt nanoparticles, and a thin layer of MnO2 nanoflakes) are strategically combined into a single entit...

Starting from Lagrangian principles we develop a formalism suitable for describing coupled optical parity-time symmetric systems.

Inelastic nuclear resonant scattering spectra of Fe atoms were measured on crystalline alloys of Pt3 Fe that were chemically disordered, partially ordered, and L12 ordered. Phonon partial density of states curves for Fe were obtained from these spectra. Upon disordering, about 10% of the spectral intensity underwent a distinct shift from 25 to 19 meV. This change in optical modes accounted for ...

there is considerable agreement among linguists that thematic analysis offers writers insights into manuscripts that may be rejected by international journals due to thematic organization problems. whereas many comparative studies have provided valuable information about thematic progression (tp), the role of peripheral themes (pts) has almost been neglected. using the revised model of the tp p...
