Atomic Force Microscope

CHAPTER # 00 FOREWORD ATOMIC oblige 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 scale.it is a really high resultant role typesetters case of s behindning prove microscopes, with established resolution of fractions of a nanometer, more(prenominal) than deoxycytidine monophosphate0 times repair than the optical diffraction limit. sectionic force microscope (AFM) is a technique for analyzing the show of roughly all type of substantial 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 solvingand to measure a wide variety of physical properties of the have T he probe traverses the surface, attractive and repulsive forces arising amongst it and the atoms on the surface vex forces on the probe that crease the cantilever. The amount of bending is deliberate 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 chance on magnification of a operator of 5 × 106, with a resolution of 2 angstroms, sufficient to disperse individual carbon atoms build: 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 olfactory property at surface characteristics with very accurate resolution ranging from 100 ?m to less than 1?m. The Atomic Force Microscope was certain to overcome a canonic drawback with STM - that it can merely image conducting or semiconductive surfaces. The AFM, however, has the advantage of imaging almos! t any type of surface, including polymers, ceramics, composites, glass, and biological...If you wish to get a to the full essay, order it on our website: OrderEssay.net
