The monograph is devoted to the consideration of methods of raster electron microscopy (REM) in relation to nanotechnology and includes not only the study of the characteristics of various nanomaterials, nanostructures and nanoobjects, but also the technology of their manufacture in situ. The book, edited by well-known scientists, contains articles and reviews of prominent specialists in areas related to nanotechnology. Various types of REM are considered, including high-resolution translucent microscopes, X-ray microanalysis, the latest methods of image acquisition by means of back-scattered electrons, as well as methods of electron cryomycroscopy for the study of bioobjects .. The use of REM includes the study of nanoparticles, nanowires, nanotubes, three-dimensional nanostructures, quantum dots, magnetic nanomaterials, photonic crystals, and biological nanostructures. The book is intended not only for a wide range of practical specialists in the field of nanotechnology, but can also be used by university students and developers of new types of raster electron microscopes.
