This research investigated different types of convex contractions in the setting of extended $ b $-metric spaces from the point of view of the existence and uniqueness of their fixed points. The assumptions imposed on involved mappings refer to conve

The valence band (VB) electronic structure and VB alignments at heterointerfaces of strained epitaxial stannate ASnO3 (A=Ca, Sr, and Ba) thin films are characterized using in situ X-ray and ultraviolet photoelectron spectroscopies, with band gaps eva

Here we use density functional theory calculations to study the impact of various spin configurations of magnetic ions on structure and properties of BiFeO3 (BFO). Low-spin and intermediate-spin electronic configurations of Fe in tetragonal BFO impac

Polycrystalline BiFeO3 (BFO) films have been prepared by using magnetic-field-assisted pulsed laser deposition (PLD), and the microstructure and ferroelectric properties have been investigated. A high deposition rate has been achieved, and a columnar

Ferroelectric materials are currently integrated in nonvolatile memory devices, whose principle is to allocate 0 and 1 logic bits to opposite orientations of the spontaneous polarization vector that are permitted by crystal symmetry. Typically made o

Stoichiometric films were prepared by rf-magnetron sputtering from a Pb(Zr 0.54 Ti 0.46 )O 3 ceramic target onto Au-electroded substrates of alumina. During deposition the substrate holder was kept at a temperature of 300 °C. Post-deposition heat tr

Ba(Zr x Ti 1− x )O 3 ceramics with x = 0.10 and 0.18 prepared via solid state, with high-density, homogeneous microstructures and similar grain size were investigated. The dielectric data showed that the relaxor properties are induced by increasing

In this paper we reexamine the possibility of using ferroelectric materials for adaptive learning artificial intelligence applications, by exploiting their capability to be set in electrically-controlled multivalue polarization states. Our experiment
