Download or read book Helium Ion Microscopy written by Gregor Hlawacek and published by Springer. This book was released on 2016-10-04 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the fundamentals of Helium Ion Microscopy (HIM) including the Gas Field Ion Source (GFIS), column and contrast formation. It also provides first hand information on nanofabrication and high resolution imaging. Relevant theoretical models and the existing simulation approaches are discussed in an extra section. The structure of the book allows the novice to get acquainted with the specifics of the technique needed to understand the more applied chapters in the second half of the volume. The expert reader will find a complete reference of the technique covering all important applications in several chapters written by the leading experts in the field. This includes imaging of biological samples, resist and precursor based nanofabrication, applications in semiconductor industry, using Helium as well as Neon and many more. The fundamental part allows the regular HIM user to deepen his understanding of the method. A final chapter by Bill Ward, one of the pioneers of HIM, covering the historical developments leading to the existing tool complements the content.

Available in PDF, EPUB and Kindle. Book excerpt: Helium Ion Microscopy: Principles and Applications describes the theory and discusses the practical details of why scanning microscopes using beams of light ions – such as the Helium Ion Microscope (HIM) – are destined to become the imaging tools of choice for the 21st century. Topics covered include the principles, operation, and performance of the Gaseous Field Ion Source (GFIS), and a comparison of the optics of ion and electron beam microscopes including their operating conditions, resolution, and signal-to-noise performance. The physical principles of Ion-Induced Secondary Electron (iSE) generation by ions are discussed, and an extensive database of iSE yields for many elements and compounds as a function of incident ion species and its energy is included. Beam damage and charging are frequently outcomes of ion beam irradiation, and techniques to minimize such problems are presented. In addition to imaging, ions beams can be used for the controlled deposition, or removal, of selected materials with nanometer precision. The techniques and conditions required for nanofabrication are discussed and demonstrated. Finally, the problem of performing chemical microanalysis with ion beams is considered. Low energy ions cannot generate X-ray emissions, so alternative techniques such as Rutherford Backscatter Imaging (RBI) or Secondary Ion Mass Spectrometry (SIMS) are examined.

Available in PDF, EPUB and Kindle. Book excerpt: Electrons, Neutrons and Protons in Engineering focuses on the engineering significance of electrons, neutrons, and protons. The emphasis is on engineering materials and processes whose characteristics may be explained by considering the behavior of small particles when grouped into systems such as nuclei, atoms, gases, and crystals. This volume is comprised of 25 chapters and begins with an overview of the relation between science and engineering, followed by a discussion on the microscopic and macroscopic domains of matter. The next chapter presents the basic relations involving mechanics, electricity and magnetism, light, heat, and related subjects which are most significant in the study of modern physical science. Subsequent chapters explore the nucleus and structure of an atom; the concept of binding forces and binding energy; the configuration of the system of the electrons surrounding the atomic nucleus; physical and chemical properties of atoms; and the structure of gases and solids. The energy levels of groups of particles are also considered, along with the Schrödinger equation and electrical conduction through gases and solids. The remaining chapters are devoted to nuclear fission, nuclear reactors, and radiation. This book will appeal to physicists, engineers, and mathematicians as well as students and researchers in those fields.

Download or read book Dissociative Recombination of Molecular Ions with Electrons written by Steven L. Guberman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dissociative Recombination of Molecular Ions with Electrons is a comprehensive collection of refereed papers describing the latest developments in dissociative recombination research. The papers are written by the leading researchers in the field. The topics covered include the use of microwave afterglows, merged beams and storage rings to measure rate coefficients and to identify the products and their yields. The molecules studied range in size from the smallest, H2+, to bovine insulin ions. The theoretical papers cover the important role of Rydberg states and the use of wave packets and quantum defect theory to deduce cross sections, rate constants and quantum yields. Several theoretical and experimental papers address the controversial topic of H3+ dissociative recombination and its importance in the interstellar medium. Dissociative recombination studies of other molecular ions in the interstellar medium and in cometary and planetary atmospheres are covered. Ionization is an important competitive process to dissociative recombination and its competition with predissociation and its role in the reverse process of the association of neutral species is presented. Dissociative attachment, in which an electron attaches to a neutral molecule, has many similarities to dissociative recombination. The topics covered include the accurate calculation of electron affinities, attachment to molecules, clusters, and to species absorbed on solid surfaces and electron scattering by a molecular anion.
