Book Description
Mechanical stress can be used to improve the device properties. Five commonly used mechanical stress study methods are enumerated in this thesis. However, only ultra-thin membrane and AFM method are suitable for applying the force to the nanostructures to realize the static and dynamic deformation. The mathematic model of AFM and ultra-thin membrane method can be obtained according to Euler-Bernoulli beam and thin-plate theory. Relaying on the FEM simulations, we find the nanostructure optimal orientation and position on membrane. Additionally, the transducer element properties are analysed at nanoscale. We focus on the piezoresistive and piezoelectric nanostructure. For piezoresistive transducer element, we introduce physical origin of the p-type silicon nanowire, single wall carbon nanotube. The innovative tunnel junctional nanostructures are also proposed. For piezoelectric nanostructure, an original AFM investigation method is presented. Our study can help us to adequately understand the electric transport behaviour of nanostructure at nanoscale under the mechanical stress impact and to design the innovation NEMS.

Book Description
This book is derived from the proceedings of the International Workshop on Nanomechanics held at Asilomar Conference Grounds in Pacific Grove, California on July 14-17, 2004. Approximately 70 leading experts from academia, government and industrial sectors in semiconductors, computers, communication, information technology, defense, energy, transportation and aerospace attended the Workshop (see the workshop photo taken on July 16, 2004). The main objective was to convene leading researchers in the nanotechnology community to assess the current state-of-the-art and disseminate recent progress, critical issues, barriers to applications, and directions for future research in nanomechanics. Miniaturization of structural components and functional devices such as electronic, optical, mechanical and electric-magnetic parts has been a recent trend, and the pace has accelerated over the past few years. Advances in micromanufacturing, semiconductor processing (e.g., etching, lithography, grafting, etc.), sensors, actuators and microprocessors have opened up a revolutionary path to the development of new technologies such as micro-electro-mechanical systems (MEMS), nano-electro-mechanical systems (NEMS), micro-engines, smart structures, smart controllers, lab-- a-chip devices, and even bio-medical sensing devices which can detect, analyze, decide and activate appropriate functions in real time. The above-mentioned devices, structures, or systems, have one issue in common. In order to perform their assigned functions, they must maintain their structural integrity and be reliable and durable during their entire designed service life. Thus, strength, durability, and time-dependent mechanical property degradation are major concerns for design engineers and device manufacturers, even though the parts are designed for electronic, magnetic, optical or other functions.

Book Description
Nanoscale and nanostructured materials have exhibited different physical properties from the corresponding macroscopic coarse-grained materials due to the size confinement. As a result, there is a need for new techniques to probe the mechanical behavior of advanced materials on the small scales. Micro and Nano Mechanical Testing of Materials and Devices presents the latest advances in the techniques of mechanical testing on the micro- and nanoscales, which are necessary for characterizing the mechanical properties of low-dimensional materials and structures. Written by a group of internationally recognized authors, this book covers topics such as: Techniques for micro- and nano- mechanical characterization; Size effects in the indentation plasticity; Characterization of low-dimensional structure including nanobelts and nanotubes; Characterization of smart materials, including piezoelectric materials and shape memory alloys; Analysis and modeling of the deformation of carbon-nanotubes. Micro and Nano Mechanical Testing of Materials and Devices is a valuable resource for engineers and researchers working in the area of mechanical characterization of advanced materials.

Book Description
Wave Propagation in Nanostructures describes the fundamental and advanced concepts of waves propagating in structures that have dimensions of the order of nanometers. The book is fundamentally based on non-local elasticity theory, which includes scale effects in the continuum model. The book predominantly addresses wave behavior in carbon nanotubes and Graphene structures, although the methods of analysis provided in this text are equally applicable to other nanostructures. The book takes the reader from the fundamentals of wave propagation in nanotubes to more advanced topics such as rotating nanotubes, coupled nanotubes, and nanotubes with magnetic field and surface effects. The first few chapters cover the basics of wave propagation, different modeling schemes for nanostructures and introduce non-local elasticity theories, which form the building blocks for understanding the material provided in later chapters. A number of interesting examples are provided to illustrate the important features of wave behavior in these low dimensional structures.

Book Description
The fabrication of MEMS has been predominately achieved by etching the polysilicon material. However, new materials are in large demands that could overcome the hurdles in fabrication or manufacturing process. Although, an enormous amount of work being accomplished in the area, most of the information is treated as confidential or privileged. It is extremely hard to find the meaningful information for the new or related developments. This book is collection of chapters written by experts in MEMS and NEMS technology. Chapters are contributed on the development of new MEMS and NEMS materials as well as on the properties of these devices. Important properties such as residual stresses and buckling behavior in the devices are discussed as separate chapters. Various models have been included in the chapters that studies the mode and mechanism of failure of the MEMS and NEMS. This book is meant for the graduate students, research scholars and engineers who are involved in the research and developments of advanced MEMS and NEMS for a wide variety of applications. Critical information has been included for the readers that will help them in gaining precise control over dimensional stability, quality, reliability, productivity and maintenance in MEMS and NEMS. No such book is available in the market that addresses the developments and failures in these advanced devices.

Book Description
Experimental Characterization, Predictive Mechanical and Thermal Modeling of Nanostructures and Their Polymer Composite focuses on the recent observations and predictions regarding the size-dependent mechanical properties, material properties and processing issues of carbon nanotubes (CNTs) and other nanostructured materials. The book takes various approaches, including dedicated characterization methods, theoretical approaches and computer simulations, providing a detailed examination of the fundamental mechanisms governing the deviations of the properties of CNTs and other nanostructured materials. The book explores their applications in materials science, mechanics, engineering, chemistry and physics due to their unique and appealing properties. The use of such materials is, however, still largely limited due to the difficulty in tuning their properties and morphological and structural features. Presents a thorough discussion on how to effectively model the properties of carbon nanotubes and their polymer nanocomposites Includes a size-dependent analysis of properties and multiscale modeling Outlines the fundamentals and procedures of computational modeling as it is applied to carbon nanotubes and other nanomaterials
