This book was released on 2012 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: A remote-sensing acoustic method for implementing position control feedback in Scanning Probe Microscopy (SPM) is presented. The capabilities of this feedback control using the new Whispering Gallery Acoustic Sensing (WGAS) method is demonstrated in a Shear-force Scanning Probe Microscope that uses a sharp probe attached to a piezoelectric Quartz Tuning Fork (QTF) firmly mounted on the microscope's frame. As the QTF is electrically driven its mechanical response reaches the SPM frame which then acts as a resonant cavity producing acoustic modes measured with an acoustic sensor strategically placed on the SPM head. The novelty of the WGAS resides in using an SPM frame with a perimeter closely matching the intervening acoustic wavelength to act as a resonant cavity. The whispering gallery cavity constitutes an acoustic amplifier for the mechanical motion of the QTF probe. The observed monotonic behavior of the whispering gallery acoustic signal as a function of the probe sample distance is exploited here for tip-sample distance control with nanometer sensitivity, thus allowing topographic characterization as the probe is scanned across the sample's surface. This thesis includes a description of a Labview based programming for the Field Programmable Gate Array (FPGA) card used in the automated control of the WGAS feedback microscope, a solution for improving the effective resolution of the Digital to Analog Converter (DAC) and initial results towards theoretically modeling the WGAS working principle.
Download or read book Acoustic Scanning Probe Microscopy written by Francesco Marinello and published by Springer Science & Business Media. This book was released on 2012-10-04 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: The combination of atomic force microscopy with ultrasonic methods allows the nearfield detection of acoustic signals. The nondestructive characterization and nanoscale quantitative mapping of surface adhesion and stiffness or friction is possible. The aim of this book is to provide a comprehensive review of different scanning probe acoustic techniques, including AFAM, UAFM, SNFUH, UFM, SMM and torsional tapping modes. Basic theoretical explanations are given to understand not only the probe dynamics but also the dynamics of tip surface contacts. Calibration and enhancement are discussed to better define the performance of the techniques, which are also compared with other classical techniques such as nanoindentation or surface acoustic wave. Different application fields are described, including biological surfaces, polymers and thin films.

Download or read book Scanning Probe Microscopy of Functional Materials written by Sergei V. Kalinin and published by Springer Science & Business Media. This book was released on 2010-12-13 with total page 563 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this book is to provide a general overview of the rapidly developing field of novel scanning probe microscopy (SPM) techniques for characterization of a wide range of functional materials, including complex oxides, biopolymers, and semiconductors. Many recent advances in condensed matter physics and materials science, including transport mechanisms in carbon nanostructures and the role of disorder on high temperature superconductivity, would have been impossible without SPM. The unique aspect of SPM is its potential for imaging functional properties of materials as opposed to structural characterization by electron microscopy. Examples include electrical transport and magnetic, optical, and electromechanical properties. By bringing together critical reviews by leading researchers on the application of SPM to to the nanoscale characterization of functional materials properties, this book provides insight into fundamental and technological advances and future trends in key areas of nanoscience and nanotechnology.

Download or read book Design Modeling and Control of Nanopositioning Systems written by Andrew J. Fleming and published by Springer. This book was released on 2014-05-15 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covering the complete design cycle of nanopositioning systems, this is the first comprehensive text on the topic. The book first introduces concepts associated with nanopositioning stages and outlines their application in such tasks as scanning probe microscopy, nanofabrication, data storage, cell surgery and precision optics. Piezoelectric transducers, employed ubiquitously in nanopositioning applications are then discussed in detail including practical considerations and constraints on transducer response. The reader is then given an overview of the types of nanopositioner before the text turns to the in-depth coverage of mechanical design including flexures, materials, manufacturing techniques, and electronics. This process is illustrated by the example of a high-speed serial-kinematic nanopositioner. Position sensors are then catalogued and described and the text then focuses on control. Several forms of control are treated: shunt control, feedback control, force feedback control and feedforward control (including an appreciation of iterative learning control). Performance issues are given importance as are problems limiting that performance such as hysteresis and noise which arise in the treatment of control and are then given chapter-length attention in their own right. The reader also learns about cost functions and other issues involved in command shaping, charge drives and electrical considerations. All concepts are demonstrated experimentally including by direct application to atomic force microscope imaging. Design, Modeling and Control of Nanopositioning Systems will be of interest to researchers in mechatronics generally and in control applied to atomic force microscopy and other nanopositioning applications. Microscope developers and mechanical designers of nanopositioning devices will find the text essential reading.
