Epitaxial BiFeO3 multiferroic thin film heterostructures.
Enhancement of polarization and related properties in heteroepitaxially constrained thin films of the ferroelectromagnet, BiFeO3, is reported. Structure analysis indicates that the crystal structure of film is monoclinic in contrast to bulk, which is rhombohedral. The films display a room-temperature spontaneous polarization (50 to 60 microcoulombs per square centimeter) almost an order of magn...
متن کاملDomain wall resistivity in epitaxial thin film
This article reviews our recent experimental studies of domain wall (DW) resistivity in epitaxial transition metal ferromagnetic thin film microstructures with stripe domains. The results are presented and analysed in the context of models of DW scattering and conventional magnetoresistance (MR) effects in ferromagnetic metals. Microstructures of progressively higher magnetic anisotropy and thu...
متن کاملModeling and Control of Epitaxial Thin Film Growth
Thin film deposition is a manufacturing process in which tolerances may approach the size of individual atoms. The final film is highly sensitive to the processing conditions, which can be intentionally manipulated to control film properties. A lattice model of surface evolution during thin film growth captures many important features, including the nucleation and growth of clusters of atoms an...
متن کاملAtomic Structure and Properties of Epitaxial Thin-film Semiconductor Interfaces
Using high-resolution transmission electron microscopy we have studied atomic structure of interfaces between epitaxial thin films of metals, insulators or semiconductors on semiconductors. For epitaxial cobalt and nickel disilicide we find exceptionally uniform interfaces with a significant dependence of the schottky barrier height on interface structure. For epitaxial alkaline-earth fluorides...
متن کاملDepth resolved lattice-charge coupling in epitaxial BiFeO3 thin film
For epitaxial films, a critical thickness (tc) can create a phenomenological interface between a strained bottom layer and a relaxed top layer. Here, we present an experimental report of how the tc in BiFeO3 thin films acts as a boundary to determine the crystalline phase, ferroelectricity, and piezoelectricity in 60 nm thick BiFeO3/SrRuO3/SrTiO3 substrate. We found larger Fe cation displacemen...
