Available in PDF, EPUB and Kindle. Book excerpt: As a result of the progress towards, and potential realized in electronic and optical device applications, the interest in epitaxial oxide thin films continue to flourish. The understanding of epitaxial oxide heterostructures has progressed, including magnetic, magnetoresistive, dielectric, ferroelectric and superconducting oxide materials. This book focuses on the fundamental issues of oxide epitaxy, microstructural evolution in epitaxy, and physical properties of epitaxial oxide thin films and how these issues relate to device applications. The book provides a vehicle through which groups of scientists working on a set of diverse phenomena could interact and present findings on very common specific themes involving similar materials. Due to the explosive growth of work in the area of colossal magnetoresistive (CMR) materials, especially in epitaxial form, the book also offers a forum to critically examine the fundamental nature of CMR in epitaxial oxide thin films and the relationship between CMR and defect structure. Other areas of emphasis include: ferroelectric memories, nonlinear optical waveguides, microwave electronics and magnetic oxide thin films.

Available in PDF, EPUB and Kindle. Book excerpt: Our understanding and control of epitaxial oxide heterostructures has progressed along multiple frontiers including magnetic, dielectric, ferroelectric, and superconducting oxide materials. This has resulted in both independent rediscovery and the successful borrowing of ideas from ceramic science, solid-state physics, and semiconductor epitaxy. A new field of materials science has emerged which aims at the use of the intrinsic properties of various oxide materials in single-crystal thin-film form. Exploiting the potential of these materials, however, will only be possible if many fundamental and engineering questions can be answered. This book represents continued progress toward fulfilling that promise. Technical information on epitaxial oxide thin films from industry, academia and government laboratories is presented. Topics include: dielectrics; ferroelectrics; optics; superconductors; magnetics; magnetoresistance.

Available in PDF, EPUB and Kindle. Book excerpt: Epitaxial oxide thin films are used in many technologically important device applications. This work deals with the deposition and characterization of epitaxial WO3 and SrBi2Ta2O9 (SBT) thin films on single crystal oxide substrates. WO3 thin films were chosen as a subject of study because of recent findings of superconductivity at surfaces and twin boundaries in the bulk form of this oxide. Highly epitaxial thin films would be desirable in order to be able to create a device within a film without patterning it, by locally creating superconducting regions (e.g. twins) within an otherwise defect free film by reducing or doping the film with Na. Films were deposited by reactive magnetron sputtering at various temperatures on single crystal SrTiO3 (100) and R-sapphire substrates. X-ray diffraction studies showed that the optimised films were highly (001) oriented, quality of epitaxy improving with decreasing deposition temperature. AFM studies revealed columnar growth of these films. Films were heat treated with Na vapour in order to reduce or dope them with Na. Low temperature measurements of the reduced films did not show existence of any superconductivity. SBT is a ferroelectric oxide and its thin films are attractive candidates for non-volatile ferroelectric random access memory (FRAM) applications. High structural anisotropy leads to a high degree of anisotropy in its ferroelectric properties which makes it essential to study epitaxial SBT films of different orientations. In this study, SBT films of different orientations were deposited on different single crystal substrates by pulsed laser ablation. Highly epitaxial c-axis oriented and smooth SBT films were deposited on SrTiO3 (100) substrates. AFM studies revealed the growth of these films by 3-D Stranski-Krastanov mode. However, these films did not exhibit any ferroelectric activity. Highly epitaxial (116)-oriented films were deposited on SrTiO3 (110) substrates. These films were also very smooth with root mean square (RMS) roughness of 15-20 Å. Films deposited on TiO2 (110) were partially a-/b-axis oriented and showed the formation of c-axis oriented SBT and many impurities. Completely a-/b-axis oriented SBT films were deposited on LaSrAlO4 (110) substrates. Films deposited at non-optimal growth temperatures showed the formation of many impurities. Attempts were also made towards depositing Sr2RuO4 films on LaSrAlO4 (110) substrates, which can act as a bottom electrode for ferroelectric SBT films.

Available in PDF, EPUB and Kindle. Book excerpt: Using the deposition method best suited for depositing an oxide thin film can be the difference between measuring the intrinsic properties of the thin film and measuring extrinsic properties arising from defects, impurity phases, and contamination. In this work, unique synthesis routes for the deposition of three epitaxial oxide thin films is presented. Applying these new routes, new material properties were able to be discerned that had been concealed in thin films deposited utilizing conventional methods. Dual off-axis RF sputtering of Bi-rich BiFeO3̳ targets was employed to deposit a 1 [mu]m-thick multiferroic BiFeO3̳ film on various (111)p̳c̳-orientated substrates with cubic and orthorhombic symmetries. Using non-resonant x-ray magnetic scattering (NXMS) and neutron diffraction, the magnetic domain populations in the BiFeO3̳ were measured. We found that growing on reduced-symmetry substrate NdGaO3̳ (011)o̳, yields a BiFeO3̳ film with a single ferroelectric, structural, and magnetic domain consistent across the whole sample. The single domain remains stable even after switching a region of the sample ferroelectrically up to 10,000 times. Using NXMS polarimetry we confirm that there is a change in the magnetic polarity of the BiFeO3̳ domain after ferroelectric switching, demonstrating the coupling of the magnetic and ferroelectric orders in monodomain (111)p̳c̳-orientated BiFeO3 ̳ thin films. Using reactive RF sputtering of a pure Fe target, phase pure deposition of antiferromagnetic insulator [alpha]-Fe2O3̳ was achieved. SQUID magnetometry confirms the absence of any ferromagnetic minority domains in the film. We showed that the Morin transition temperature, above which [alpha]-Fe2̳O3̳ has a weak canted moment, decreases when reducing the thickness of the film. For films 10 nm and thinner, the Morin transition was suppressed completely. Using the XMLD contrast of the 10 nm-thick [alpha]-Fe2̳O3̳ film, X-ray Photoemission Electron Microscopy (PEEM) measurements uncovered a complex mosaic of sub-micron size antiferromagnetic domains connected by a network of antiferromagnetic spin vortices. The vortices were mostly found in vortex/antivortex pairs which could be annihilated through the application of an external magnetic field. When a 1 nm-thick Co layer was overlayed, the mosaic of domains present in the [alpha]-Fe2̳O3̳ was coupled to the Co which takes on the same mosaic pattern. Pulsed laser deposition of SrO and chemical vapor deposition of a TiO2̳ precursor gas were used simultaneously to deposit high quality SrTiO3 thin films in a hybrid deposition technique we called metal-organic pulsed laser deposition (MOPLD). We demonstrated a conductive 2-dimensional electron gas (2DEG) at the interface between MOPLD-grown SrTiO3 and PLD-grown LaAlO3̳, indicative that the SrTiO3̳ thin film is highly stoichiometric. The increased stoichiometry control afforded by MOPLD also grants the ability to control the point defects in the system. By decreasing the abundance of point defects, quantum properties of SrTiO3̳ become accessible.
