Book Description
Crack initiation and growth are key issues when it comes to the mechanical reliab- ity of microelectronic devices and microelectromechanical systems (MEMS). Es- cially in organic electronics where exible substrates will play a major role these issues will become of utmost importance. It is therefore necessary to develop me- ods which in situ allow the experimental investigation of surface deformation and fracture processes in thin layers at a micro and nanometer scale. While scanning electron microscopy (SEM) might be used it is also associated with some major experimental drawbacks. First of all if polymers are investigated they usually have to be coated with a metal layer due to their commonly non-conductive nature. Additi- ally they might be damaged by the electron beam of the microscope or the vacuum might cause outgasing of solvents or evaporation of water and thus change material properties. Furthermore, for all kinds of materials a considerable amount of expe- mental effort is necessary to build a tensile testing machine that ts into the chamber. Therefore, a very promising alternative to SEM is based on the use of an atomic force microscope (AFM) to observe in situ surface deformation processes during straining of a specimen. First steps towards this goal were shown in the 1990s in [1–4] but none of these approaches truly was a microtensile test with sample thicknesses in the range of micrometers. To the authors’ knowledge, this was shown for the rst time by Hild et al. in [5]. 16.

Physics at Surfaces
Author: Andrew Zangwill
Publisher: Cambridge University Press
ISBN: 1316583260
Category : Science
Languages : en
Pages : 470
Book Description
Physics at Surfaces is a unique graduate-level introduction to the physics and chemical physics of solid surfaces, and atoms and molecules that interact with solid surfaces. A subject of keen scientific inquiry since the last century, surface physics emerged as an independent discipline only in the late 1960s as a result of the development of ultra-high vacuum technology and high speed digital computers. With these tools, reliable experimental measurements and theoretical calculations could at last be compared. Progress in the last decade has been truly striking. This volume provides a synthesis of the entire field of surface physics from the perspective of a modern condensed matter physicist with a healthy interest in chemical physics. The exposition intertwines experiment and theory whenever possible, although there is little detailed discussion of technique. This much-needed text will be invaluable to graduate students and researchers in condensed matter physics, physical chemistry and materials science working in, or taking graduate courses in, surface science.

Molecular Interactions
Author: Aurelia Meghea
Publisher: BoD – Books on Demand
ISBN: 9535100793
Category : Medical
Languages : en
Pages : 386
Book Description
In a classical approach materials science is mainly dealing with interatomic interactions within molecules, without paying much interest on weak intermolecular interactions. However, the variety of structures actually is the result of weak ordering because of noncovalent interactions. Indeed, for self-assembly to be possible in soft materials, it is evident that forces between molecules must be much weaker than covalent bonds between the atoms of a molecule. The weak intermolecular interactions responsible for molecular ordering in soft materials include hydrogen bonds, coordination bonds in ligands and complexes, ionic and dipolar interactions, van der Waals forces, and hydrophobic interactions. Recent evolutions in nanosciences and nanotechnologies provide strong arguments to support the opportunity and importance of the topics approached in this book, the fundamental and applicative aspects related to molecular interactions being of large interest in both research and innovative environments. We expect this book to have a strong impact at various education and research training levels, for young and experienced researchers from both academia and industry.
