An ideal text for students as well as practitioners, this is a comprehensive introduction to the field of scanning electron microscopy (SEM) and X-ray microanalysis. The authors emphasize the practical aspects of the techniques described.
In the decade since the publication of the second edition of Scanning Electron Microscopy and X-Ray Microanalysis, there has been a great expansion in the capabilities of the basic scanning electron microscope (SEM) and the x-ray spectrometers. The emergence of the variab- pressure/environmental SEM has enabled the observation of samples c- taining water or other liquids or vapor and has allowed for an entirely new class of dynamic experiments, that of direct observation of che- cal reactions in situ. Critical advances in electron detector technology and computer-aided analysis have enabled structural (crystallographic) analysis of specimens at the micrometer scale through electron backscatter diffr- tion (EBSD). Low-voltage operation below 5 kV has improved x-ray spatial resolution by more than an order of magnitude and provided an effective route to minimizing sample charging. High-resolution imaging has cont- ued to develop with a more thorough understanding of how secondary el- trons are generated. The ?eld emission gun SEM, with its high brightness, advanced electron optics, which minimizes lens aberrations to yield an - fective nanometer-scale beam, and through-the-lens detector to enhance the measurement of primary-beam-excited secondary electrons, has made high-resolution imaging the rule rather than the exception. Methods of x-ray analysis have evolved allowing for better measurement of specimens with complex morphology: multiple thin layers of different compositions, and rough specimens and particles. Digital mapping has transformed classic x-ray area scanning, a purely qualitative technique, into fully quantitative compositional mapping.
The text has been used in educating over 3,000 students at the Lehigh SEM short course as well as thousands of undergraduate and graduate students at universities in every corner of the globe
The authors have made extensive changes to the text and figures in this edition as a result of their experience in teaching the various concepts of SEM and x-ray microanalysis

This text provides students as well as practitioners (engineers, technicians, physical and biological scientists, clinicians, and technical managers) with a comprehensive introduction to the field of scanning electron microscopy (SEM) and X-ray microanalysis. The authors emphasize the practical aspects of the techniques described. Topics discussed include user-controlled functions of scanning electron microscopes and x-ray spectrometers, the characteristics of electron beam - specimen interactions, image formation and interpretation, the use of x-rays for qualitative and quantitative analysis and the methodology for structural analysis using electron back-scatter diffraction. SEM sample preparation methods for hard materials, polymers, and biological specimens are covered in separate chapters. In addition techniques for the elimination of charging in non-conducting specimens are detailed. A data base of useful parameters for SEM and X-ray micro-analysis calculations and enhancements to the text chapters are available on an accompanying CD.
