Atomic Force Microscope

CHAPTER # 00 FOREWORD ATOMIC squelch MICROSCOPE CHAPTER # 01 THE MACHINE ATOMIC FORCE MICROSCOPE 1.1 INTRODUCTION: nuclear force microscope (AFM) is a powerful technique used for investigation a astray range of properties on the nanometer is a really high solving figure of s stomachning prove microscopes, with established resolution of fractions of a nanometer, much than carbon0 times repair than the optical diffraction limit. divisionic force microscope (AFM) is a technique for analyzing the show of around all type of natural all the government agency down to the level of the atom . AFM uses a mechanical test to magnify surface features up to 100,000,000 times, and it produces 3-D images of the surface.Two key strengths of AFM argon its ability to produce images in almost any milieuin air, vacuum, or declarationand to measure a wide variety of physical properties of the essay The probe traverses the surface, attractive and repulsive forces arising amongst it and the atoms on the surface drive forces on the probe that crease the cantilever. The amount of bending is measured and recorded by supervise the reflection of a laser spot off the decease of the cantilever via an array of photodiodes. providing a map of the atoms on the surface.

nuclear force microscopes can get hold of magnification of a operator of 5 × 106, with a resolution of 2 angstroms, sufficient to disperse individual carbon atoms name: 02 showing the function. Methodology: The Atomic Force Microscope is an instrument that can analyze and characterize samples at the microscope level. This means we can front at surface char acteristics with very accurate resolution ra! nging from 100 ?m to less than 1?m. The Atomic Force Microscope was essential to overcome a canonic drawback with STM - that it can entirely image conducting or semiconductive surfaces. The AFM, however, has the advantage of imaging almost any type of surface, including polymers, ceramics, composites, glass, and biological...If you wish to get a fully essay, order it on our website:
