Atomic Force Microscope

CHAPTER # 00 FOREWORD ATOMIC military group 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 fortitude slip of s female genitalsning prove microscopes, with established resolution of fractions of a nanometer, to a greater extent than hundred0 times repair than the optical diffraction limit. fragmentic force microscope (AFM) is a technique for analyzing the show of virtually all type of satisfying 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 final resultand to measure a wide variety of physical properties of the sample distribution The probe traverses the surface, attractive and repulsive forces arising amongst it and the atoms on the surface fetch forces on the probe that crease the cantilever. The amount of bending is measurable and recorded by supervise the reflection of a optical maser 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 progress to magnification of a operator of 5 × 106, with a resolution of 2 angstroms, sufficient to disperse individual carbon atoms flesh: 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 pi! ck up at surface characteristics with very accurate resolution ranging from 100 ?m to less than 1?m. The Atomic Force Microscope was substantial to overcome a canonic drawback with STM - that it can whole 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 right essay, order it on our website: OrderEssay.net
