This book was released on 2014-06-05 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wide variety of materials systems and deposition strategies have been developed to produce epitaxial and polycrystalline thin films. In particular, controlling the morphology and microstructure of metal films at the nanometer and/or micron scale has become crucial for applications such as giant magnetoresistive devices, contacts and diffusion barriers in integrated circuits and photovoltaics, and multilayer X-ray mirrors. This book, first published in 2001, focuses on the interactions between different mechanisms of microstructure evolution and film-growth conditions. Two sections of the volume, including a joint effort with Symposium R, Morphology and Dynamics of Crystal Surfaces in Molecular and Colloid Systems, highlight the fundamental mechanisms of epitaxial growth. Additional topics include: multilayers - stress in thin films; early stages of film growth - mechanical properties; texture in polycrystalline films; grain growth - barrier layers; and silicides and organic thin films - pulsed laser deposition.

Book Synopsis Growth Mechanism and Interface Effects on Microstructure of Perovskite-type Barium Titanate-based Epitaxial Films by : Jie He
Download or read book Growth Mechanism and Interface Effects on Microstructure of Perovskite-type Barium Titanate-based Epitaxial Films written by Jie He and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This work was motivated and focused on the growth mechanism, microstructures and interfaces of barium titanate, BaTiO3 (BTO), based epitaxial thin films. Transimission electron microscopy (TEM), high resolution TEM (HRTEM), electron diffraction (ED) have been mainly employed in this study for microstructure investigations of BTO-based epitaxial thin films with the assistance of other materials characterization methods, such as X-ray diffraction (XRD), atomic force microscopy (AFM), Nanoindentation testing, etc. As a basic studying model, epitaxial BTO films were first deposited on the (001) MgO substrate using RF magnetron sputtering to provide fundamental knowledge of the film growth for BTO based thin films. The epitaxial BTO films show a tetragonal crystal structure (a = 4.02 Å and c = 4.11 Å) with epitaxial nanodomains induced from the rough film/substrate interface due to the modification of the substrate surface characteristics (steps, terraces, and kinks) during the deposition process. Two new phases of - calculus [gamma]y (Ba10TiO26) and Hß (BaTi8O24) were formed on the MgO substrate using RF magnetron sputtering. The atomic structures of the two new phases were determined and examined. The [gamma]y phase has a monoclinic structure, Cm, a=16.49 Å̊̊, b=8.94 Å, c=3.94 Å, y=77°. The Hß phase has a monoclinic structure, Cm, a = 17.88̊Å̊, b = 7.21Å, c = 3.94 Å̊̊̊, y =82°. Both [gamma]y and Hß phases have four different oriented domains. The orientation relationship between domains and MgO substrate is discussed. Initail study shows that these new phases possess novel and interesting properties. The doped BTO films with different dopant (Sr2 and Zr4) fabricated using pulsed laser deposition (PLD) have been studied for doping effects, interface effects and film growth mechanism. The (Ba, Sr)TiO3 (BST) epitaxial films grown on 1.2° and 5.3° miscut substrates consist of lager commensurate domains, and correspondly show higher dielectric constant and dielectric tunability, and lower average modulus and hardness than those of the films grown on the 3.5° miscut substrate. The results suggest that the differences on the interfacial structure have a tremendous effect on the properties of the films. The investigation on epitaxial Ba(Zr, Ti)O3 (BZT) and 2% Mn doped Ba(Zr, Ti)O3 (Mn:BZT) thin films grown on MgO substrate revealed the formation of twin-coupled domains on the epilayer by sharing their {111}/{110} planes as common planes. The structure evolution from epilayer to nanopillars is accomplished by alternatively introducing {111} and {110} twin boundaries, resulting in gradual shrinking or enlarging of the lateral size of the epitaxial grains/twin coupled nanopillars. The formations of twin domains, sharing planes and structure transition mechasim have been discussed in detail. Eventually, the microstructures and layer interfaces of [Mn:BZT//Mn:BST]N multilayer films consisting of 2% Mn doped (Ba, Sr)TiO3 (Mn:BST) and Mn:BZT layers on MgO (001) substrates with various deposition rates, deposition period numbers N were studied to provide an integral view of the formation of multilayer films in BTO system. All the [Mn:BZT//Mn:BST]N multilayer films present epitaxial quality and induced {111}/{110} twin-coupled domains initially formed at different film thickness/layers. The film/substrate interface has an important role for the formation of twin domains and the proportion of twin domain structures in the entire films. The layer interfaces between Mn:BST and Mn:BZT with period compression and extension strains were observed and discussed. The microstructure evolution and structure-related nano-mechanical properties of the multilayer films have been systematically investigated.
Book Synopsis Mechanisms for Intrinsic Stress Evolution During and After Polycrystalline Film Growth by : Hang Yu (Ph. D.)
Download or read book Mechanisms for Intrinsic Stress Evolution During and After Polycrystalline Film Growth written by Hang Yu (Ph. D.) and published by . This book was released on 2013 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growth of polycrystalline films involves poorly understood kinetic processes that occur far from equilibrium and lead to complex co-evolution of the surface, microstructure and intrinsic stress of the films. Here we present a comprehensive study consisting of in situ stress measurements, microstructure characterization, and analytical modeling for various polycrystalline systems. We find that in systems of high atomic mobility, the stress change after polycrystalline film growth can be attributed to a fast reversible surface process and a slow irreversible bulk process. The fast process is weakly dependent on temperature and is associated with changes in the shape of grain surfaces. The slow process is strongly dependent on temperature and is mostly associated with grain growth in the bulk of the film. We also discovered a turnaround phenomenon in which, under conditions of intermediate atomic mobility, the stress evolves from a tensile toward a compressive state, and then turns around to evolve toward a tensile state. This stress turnaround phenomenon is strongly dependent on the substrate temperature and deposition rate, and can be attributed to an increase of the grain size during film deposition. Grain growth during deposition not only leads to a tensile component of the intrinsic stress, but also changes the grain size dependence of the compressive component. The compressive component results from incorporation of excess adatoms in grain boundaries, and the magnitude of the compressive stress is controlled by a competition between adatom incorporation in 2D islands and incorporation at grain boundaries. We also investigated the effect of the angle of incidence of the flux of depositing atoms on stress and structure evolution during polycrystalline film growth. We find that as the angle of incidence increases, the coalescence thickness increases and the stress becomes less compressive or more tensile. We attribute these phenomena to the enhanced surface roughness, the shadowing effect, the steering effect and the presence of Ehrlich-Schwoebel barriers during oblique angle deposition. All these effects lead to suppression of the adatom-grain boundary incorporation process. Based on this thesis work, intrinsic stresses in polycrystalline films can be categorized into three types: Type I, the intermediate type and Type II. These behaviors are observed in systems of low, intermediate and high atomic mobility, respectively. Compressive stresses develop in Type II behavior and tensile stresses develop in Type I behavior. The transition of the stress behavior from Type I, to the intermediate type and to Type II is continuous and can be achieved by adjusting deposition conditions. Whether the post-coalescence stress is tensile, or compressive, or evolving from compressive to tensile depends on the homologous temperature, the deposition rate and the angle of the incidence of the flux of depositing atoms.
