Dielectric properties of ultrathin SrTiO3 and meta-SrTiO3 interfaces

, 2020
Using first-principles methods, we investigate the dielectric constants of free-standing ultrathin SrTiO3 film and the dielectric response of SrTiO3 interfaced with various metal electrodes.

Large voltage-controlled magnetic anisotropy in the SrTiO3/Fe/Cu structure

, 2017
First-principles calculations are performed to investigate the magnetic anisotropy and voltage-controlled magnetic anisotropy (VCMA) in the strontium titanate (SrTiO3)-based structure.

In situ thermal preparation of oxide surfaces

APL Materials, 2020
Substrate surfaces terminated with a specific surface reconstruction are a prerequisite for the controlled epitaxial growth of most materials. Focusing on SrTiO3 (001) substrates, it has recently been shown that in situ substrate termination by thermal ...

Ultra‐Low Power Consumption and Highly Durability in Sm:HfO2 Thin Film Ferroelectric Memristor for Edge Detection

Advanced Electronic Materials, EarlyView.
ABSTRACT With the continuous development of computer image processing, developing efficient and low‐power computing devices has become a key challenge. Memristors have integrated in‐situ storage and computing capabilities, making them an ideal choice for low‐power image processing computing architectures. However, current memristors are confronted with

Formation of epitaxial BaTiO3/SrTiO3 multilayers grown on Nb-doped SrTiO3 (001) substrates

, 2002
The formation of epitaxial BaTiO3/SrTiO3 multilayers; is studied in terms of the growth mechanism by investigating surface morphologies, crystalline orientations, microstructures, and structures of the interfaces, as well as by determining the dielectric

Extrinsic and Intrinsic Charge Transfer at Interfaces of Membrane‐Based Oxide Heterostructures

Advanced Electronic Materials, EarlyView.
Freestanding oxides have emerged as a new opportunity to tailor oxides outside of the typical epitaxial constraints. We present the fabrication of TiO2‐terminated SrTiO3 membranes via direct growth control. We demonstrate competing ionic and electronic charge transfer in LaAlO3/SrTiO3 bilayers using near ambient pressure XPS.

Scan‐Path‐ and Initial‐State‐Dependent Superdomain Switching in (111)‐Oriented PZT

Advanced Electronic Materials, EarlyView.
Scan trajectory and initial superdomain topology govern polarization switching in (111)‐oriented PZT. Automated AFM writing, pulsing experiments, and interferometric 3D‐PFM show that raster scans reproducibly stabilize ordered Type‐I stripe superdomains with constrained variant selection, whereas spiral trajectories generate frustrated mixed‐variant ...

Oscillation of the multiferroic/ferroelectric GdMnO3/SrTiO3 and YbMnO3/SrTiO3 interfaces in the EPR spectrum [PDF]

, 2015
© 2015 AIP Publishing LLC. The electron paramagnetic resonance (EPR) method was used to study thin manganite ytterbium YbMnO3 and gadolinium GdMnO3 films, with a thickness of 100?nm, deposited on a SrTiO3 virtual ferroelectric backing (GdMnO3/SrTiO3 and ...

Strain distribution in epitaxial SrTiO3 thin films [PDF]

, 2006
The lattice strain distributions of epitaxial SrTiO3 films deposited on LaAlO3 were investigated by in situ x-ray diffraction at the temperature range of 25-300 K, grazing incident x-ray diffraction, and high resolution x-ray diffraction.
