This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular dynamics (MD) simulations are performed to elucidate the physics surrounding secondary ion mass spectrometry (SIMS). During SIMS, an energetic projectile is bombarded against a surface, and material is lifted off the surface and analyzed. MD simulations provide a mesoscopic view of this process in order to gather a better understanding of the underlying physics. Significant work has already been performed to explore the effects of atomic and cluster projectiles, cluster sizes at low energies, and polymer chain length on the resulting ejection dynamics. This thesis has three objectives. The first is to redefine the best conceptual model for understanding cluster bombardment. We propose a model which likens cluster projectiles to a single large particle moving through a solid. The energy decay of cluster projectiles during the bombardment process is shown to follow a friction equation at short times. In addition, the projectile motion, energy deposition, and reaction dynamics are compared between a cluster projectile and single large bead to examine the accuracy of this model. Secondly, the optimal experimental parameters for maximizing ejection yield while reducing sample damage are investigated. The effect of incident angle and cluster projectile size is examined for multiple cluster types including a series of fullerenes, Au3, benzene, and naphthalene. The results are compared with experimental data to determine which parameters contribute to the greatest quality of data. Lastly, the reaction dynamics of a dissociative water sample following C60 and Au3 bombardment is modeled. The sample is able to dissociate into OH-, H+, and O2- ions, which has a very high activation energy. Therefore, we use this sample as an indicator of where a broad range of reactions can occur for molecular sample. The results aim as garnering a better understanding of the bombardment process for both theorists and experimentalists in the SIMS. In addition, experimentalists should be able to use this information to optimize the experimental parameters in order to maximize the quality of data obtained with SIMS.

Download or read book Two Dimensional Transition Metal Dichalcogenides written by Alexander V. Kolobov and published by Springer. This book was released on 2016-07-26 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the current status of theoretical and experimental progress in 2 dimensional graphene-like monolayers and few-layers of transition metal dichalcogenides (TMDCs). Semiconducting monolayer TMDCs, due to the presence of a direct gap, significantly extend the potential of low-dimensional nanomaterials for applications in nanoelectronics and nano-optoelectronics as well as flexible nano-electronics with unprecedented possibilities to control the gap by external stimuli. Strong quantum confinement results in extremely high exciton binding energies which forms an interesting platform for both fundamental studies and device applications. Breaking of spatial inversion symmetry in monolayers results in strong spin-valley coupling potentially leading to their use in valleytronics. Starting with the basic chemistry of transition metals, the reader is introduced to the rich field of transition metal dichalcogenides. After a chapter on three dimensional crystals and a description of top-down and bottom-up fabrication methods of few-layer and single layer structures, the fascinating world of two-dimensional TMDCs structures is presented with their unique atomic, electronic, and magnetic properties. The book covers in detail particular features associated with decreased dimensionality such as stability and phase-transitions in monolayers, the appearance of a direct gap, large binding energy of 2D excitons and trions and their dynamics, Raman scattering associated with decreased dimensionality, extraordinarily strong light-matter interaction, layer-dependent photoluminescence properties, new physics associated with the destruction of the spatial inversion symmetry of the bulk phase, spin-orbit and spin-valley couplings. The book concludes with chapters on engineered heterostructures and device applications such as a monolayer MoS2 transistor. Considering the explosive interest in physics and applications of two-dimensional materials, this book is a valuable source of information for material scientists and engineers working in the field as well as for the graduate students majoring in materials science.

Book excerpt: Failure analysis is the preferred method to investigate product or process reliability and to ensure optimum performance of electrical components and systems. The physics-of-failure approach is the only internationally accepted solution for continuously improving the reliability of materials, devices and processes. The models have been developed from the physical and chemical phenomena that are responsible for degradation or failure of electronic components and materials and now replace popular distribution models for failure mechanisms such as Weibull or lognormal. Reliability engineers need practical orientation around the complex procedures involved in failure analysis. This guide acts as a tool for all advanced techniques, their benefits and vital aspects of their use in a reliability programme. Using twelve complex case studies, the authors explain why failure analysis should be used with electronic components, when implementation is appropriate and methods for its successful use. Inside you will find detailed coverage on: a synergistic approach to failure modes and mechanisms, along with reliability physics and the failure analysis of materials, emphasizing the vital importance of cooperation between a product development team involved the reasons why failure analysis is an important tool for improving yield and reliability by corrective actions the design stage, highlighting the ‘concurrent engineering' approach and DfR (Design for Reliability) failure analysis during fabrication, covering reliability monitoring, process monitors and package reliability reliability resting after fabrication, including reliability assessment at this stage and corrective actions a large variety of methods, such as electrical methods, thermal methods, optical methods, electron microscopy, mechanical methods, X-Ray methods, spectroscopic, acoustical, and laser methods new challenges in reliability testing, such as its use in microsystems and nanostructures This practical yet comprehensive reference is useful for manufacturers and engineers involved in the design, fabrication and testing of electronic components, devices, ICs and electronic systems, as well as for users of components in complex systems wanting to discover the roots of the reliability flaws for their products.
