Electrical Field Driven Structural Evolutions of Polymorphic Nanodomains in Ferroelectric Ba(Zr,Ti)O₃ Films

Structural and Electrical Properties of Polymorphic Pentacene Thin Films

Due to its outstanding carrier transport capabilities the aromatic hydrocarbon pentacene is still one of the most promising out of all organic semiconducting materials investigated so far. Pentacene appears in several polymorphic structures that significantly differ with respect to the d(001) spacing. It is shown, that precise control of the epitaxial growth process of thin films enables not on...

Thickness-dependent evolutions of domain configuration and size in ferroelectric and ferroelectric-ferroelastic films

Tunable metallic conductance in ferroelectric nanodomains.

Metallic conductance in charged ferroelectric domain walls was predicted more than 40 years ago as the first example of an electronically active homointerface in a nonconductive material. Despite decades of research on oxide interfaces and ferroic systems, the metal-insulator transition induced solely by polarization charges without any additional chemical modification has consistently eluded t...

Structural, Electrical, Magnetic and Resistive Switching Properties of the Multiferroic/Ferroelectric Bilayer Thin Films

Bi0.8Pr0.2Fe0.95Mn0.05O₃/Bi3.96Gd0.04Ti2.95W0.05O12 (BPFMO/BGTWO) bilayer thin films with Multiferroic/Ferroelectric (MF/FE) structures were deposited onto Pt(111)/Ti/SiO₂/Si(100) substrates by using the sol-gel method with rapid thermal annealing. The BPFMO/BGTWO thin films exhibited well-saturated ferromagnetic and ferroelectric hysteresis loops because of the electro-magnetic coupling induce...

Structural and electrical properties of In-doped vanadium oxide thin films prepared by spray pyrolysis

The In-doped vanadium pentoxide nanostructures with different doping levels including 0, 10, 20 and 30 at.% were prepared by the spray pyrolysis technique. The prepared thin films were characterized by the x-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD results revealed that the films were crystalline in tetragonal phase. Increasing the In-doping level made the structure...
