Download or read book Characterization of Nanostructures written by Sverre Myhra and published by CRC Press. This book was released on 2012-06-12 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: The techniques and methods that can be applied to materials characterization on the microscale are numerous and well-established. Divided into two parts, Characterization of Nanostructures provides thumbnail sketches of the most widely used techniques and methods that apply to nanostructures, and discusses typical applications to single nanoscale objects, as well as to ensembles of such objects. Section I: Techniques and Methods overviews the physical principles of the main techniques and describes those operational modes that are most relevant to nanoscale characterization. It provides sufficient technical detail so that readers and prospective users can gain an appreciation of the strengths and limitations of particular techniques. The section covers both mainstream and less commonly used techniques. Section II: Applications of Techniques to Structures of Different Dimensionalities and Functionalities deals with the methods for materials characterization of generic types of systems, using carefully chosen illustrations from the literature. Each chapter begins with a brief description of the materials and supplies a context for the methods for characterization. The volume concludes with a series of flow charts and brief descriptions of tactical issues. The authors focus on the needs of the research laboratory but also address those of quality control, industrial troubleshooting, and online analysis. Characterization of Nanostructures describes those techniques and their operational modes that are most relevant to nanoscale characterization. It is especially relevant to systems of different dimensionalities and functionalities. The book builds a bridge between generalists, who play vital roles in the post-disciplinary area of nanotechnology, and specialists, who view themselves as more in the context of the discipline.

This book was released on 2017 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scanning transmission electron microscopy (STEM) is a key tool in the advancement of materials science. As nanoscale materials and atomically sharp interfaces become increasingly technologically relevant, STEM provides feedback on the individual atoms, defects and interfaces that matter in the material. Two areas where STEM characterization is critical for materials advancement are electrochemical energy materials, such as battery electrodes and fuel cell electrocatalysts, and complex oxide materials, which exhibit a diverse array of properties. Electrochemical energy systems, including battery electrodes and electrocatalysts for fuel cells, are critical for the future of clean transportation. For these materials, investigation of the nanoscale processes which occur in liquid electrolytes is critical for understanding their performance in real devices. Encapsulating a thin layer of liquid in the TEM for in situ characterization is an exciting approach for gaining a detailed understanding of the underlying mechanisms of energy conversion and storage. The first half of this dissertation discusses the development and use of liquid-cell and electrochemical-cell TEM. First, I discuss the limitations and opportunities of EELS in thick liquids. I further discuss an electrochemical cell for the TEM, and its application to fuel cell electrocatalysts and battery materials. I was able to observe Pt-Ni octahedral catalyst particles degrade and lose their shape, and detect lithium ions move in a charging and discharging battery cathode (LiFePO4) with nanoscale detail by mapping the electronic structure. The second part of the dissertation focuses on complex oxides, which host a wide range of electronic and magnetic properties. Oxide interfaces, such as thin-film heterostructures and domain walls, are often atomically abrupt and produce novel functionalities. In particular, ferroelectric domain walls are rich sources of emergent phenomena – such as two-dimensional conductive sheets that form in an otherwise insulating solid – due to their unusual electronic properties or symmetry breaking. We probed how ferroelectric distortions change at domain walls with STEM for ErMnO3. From the STEM images, we calculated the order parameter at many domain walls in ErMnO3 to create a statistical picture of the ferroelectricity at these topological defects, and also observed how the order parameter changes near vortex structures. We further apply these methods to lutetium ferrite superlattices, where we use feedback from STEM to design a near-room-temperature multiferroic material in which ferroelectricity enhances the magnetism. We find that there are confined charged domain walls in the superlattice that additionally boost magnetism.

This book was released on 2008-12-02 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains invited and contributed papers presented at the conference on ‘Microscopy of Semiconducting Materials’ held at the University of Cambridge on 2-5 April 2007. The event was organised under the auspices of the Electron Microscopy and Analysis Group of the Institute of Physics, the Royal Microscopical Society and the Materials Research Society. This international conference was the fifteenth in the series that focuses on the most recent world-wide advances in semiconductor studies carried out by all forms of microscopy and it attracted delegates from more than 20 countries. With the relentless evolution of advanced electronic devices into ever smaller nanoscale structures, the problem relating to the means by which device features can be visualised on this scale becomes more acute. This applies not only to the imaging of the general form of layers that may be present but also to the determination of composition and doping variations that are employed. In view of this scenario, the vital importance of transmission and scanning electron microscopy, together with X-ray and scanning probe approaches can immediately be seen. The conference featured developments in high resolution microscopy and nanoanalysis, including the exploitation of recently introduced aberration-corrected electron microscopes. All associated imaging and analytical techniques were demonstrated in studies including those of self-organised and quantum domain structures. Many analytical techniques based upon scanning probe microscopies were also much in evidence, together with more general applications of X-ray diffraction methods.

Book excerpt: Today, the availability of bright and highly coherent electron sources and sensitive detectors has radically changed the type and quality of the information which can be obtained by transmission electron microscopy (TEM). TEMs are now present in large numbers not only in academia, but also in industrial research centers and fabs. This book presents in a simple and practical way the new quantitative techniques based on TEM which have recently been invented or developed to address most of the main challenging issues scientists and process engineers have to face to develop or optimize semiconductor layers and devices. Several of these techniques are based on electron holography; others take advantage of the possibility of focusing intense beams within nanoprobes. Strain measurements and mappings, dopant activation and segregation, interfacial reactions at the nanoscale, defect identification and specimen preparation by FIB are among the topics presented in this book. After a brief presentation of the underlying theory, each technique is illustrated through examples from the lab or fab.

Download or read book Ultrafast Electro thermal Transport Through Nanoscale Electronic Materials and Interfaces written by Christopher Perez and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although silicon-based nanofabrication technology has satisfied computational demands for decades, the aggressive scaling of complementary metal oxide semiconductor (CMOS) technology to sub-5 nm geometries poses challenges that must be addressed at the materials level. One example is tuning electro-thermal transport in metal nanostructures to enhance the transfer of information and the dissipation of heat in integrated circuits. The manipulation of these pathways can be further optimized by integrating low-temperature passivation materials with varying thermal conductivities. Furthermore, the emergence of photonic interconnects presents an opportunity for the integration of electro-optic components that rely heavily on the movement, transfer, and recombination of charge carriers within photosensitive materials. All the above are governed by the fundamental limits of physical transfer mechanisms in semiconductors, bringing electron and phonon engineering --the control of heat and charge carriers in materials-- to the forefront of CMOS hardware design. This work explores the fundamental mechanisms and limits of electron-phonon transport in four individual material systems which can comprise different parts of a broader, electro-thermally optimized electronic system using primarily time-domain thermoreflectance (TDTR) and scanning ultrafast electron microscopy (SUEM) as probes. First, we discuss the electro-thermal characterization of iridium (Ir) as an emerging metal for high aspect ratio nanostructures on account of its favorable resistivity scaling with thickness. The exceptionally defect-free metal films offer minimal confounding microstructural effects and allow the probing of thermal anisotropy and cross-plane quasi-ballistic thermal transport in epitaxial Ir(001) interposed between Al and MgO(001). Such effects reveal a transition between three dominant cross-plane thermal transport mechanisms which include electron dominant, phonon dominant, and electron-phonon energy conversion dominant regimes at different thicknesses. Finally, we develop a phenomenological model that correctly describes the dominant transport regimes, providing insight into the thickness-dependent interplay between carriers in metals as well as enabling quick evaluation and potential scalability to broader material systems. Next, we describe defect-modulated thermal transport in sputtered aluminum nitride (AlN) thin films for enabling wide-bandgap (WBG), high-temperature, and high-power electronic devices deposited at back-end of the line (BEOL) compatible temperatures (
