Recent advancements in Transmission Electron Microscopy is built upon the remarkable achievements of the transmission electron microscope, especially, with the aberration corrected object lens, which itself is the incoherent integration of the particle electron optics and modern wave imaging technology.This involves the particle-wave duality of electrons.This book answers questions by applying the de Broglie Hypothesis and Einstein's Theory of Relativity on the relationship between particles and electromagnetic waves to shed some light onto the electron microscopy. The first chapter explains what an electron is, which includes: (a) using the transmission electron microscope to observe the wave-particle duality of electrons, (b) the internal structure of the electron, (c) the electron as a confined electromagnetic vortices field in a corpuscle space. The following chapters, then, decipher the enigmatic relationship between the de Broglie wave of the electron and the internal electromagnetic flux circulatory motion, and analyze the spatiotemporal modification of the traveling electron corpuscle as it passes through the electron gun and magnetic lens. Based on the de Broglie wave of the traveling electron corpuscle at a certain velocity, the author defines the electron microscopy as the technology steering the velocity of the electron corpuscle assemble which encodes the information of periodic spatial grating constructed by the atoms and electromagnetic potential field, which surround the flying electrons. Then the author uses the space-time Talbot effects of the electrons to interpret the high resolution images, which was first developed by Ijima-Cowley, and expounds the contrast of the high resolution electron microscopy images as the intensity distribution of the assemble of corpuscle electron torus pulses train or beam at near field and at its far-field, which is a diffraction pattern. The final chapter of the book elaborates on how to understand the quantum electron microscopy. This book offers a comprehensive understanding what the quantum electron microscopy is, that may bring the microscopy field beyond the atom's spatial periodicity in materials.

Dr. Z. C. (Zhen Chuan) Kang received B.S in Department of Metal Physics and Chemistry at University of Beijing Science and Technology (1964), China; Dr.Sc. in Materials Science. At Université de Marseille III, France (1989). He studied diffraction physics and high resolution electron microscopy with Professor J. M.Cowley at center for solid state science in Arizon State University (1980-1982) and as a research professor in Department of Chemistry and Biochemistry at Arizona State University worked with Professor Leroy Eyring for mixed valency and non-stoichiometry of rare earth higher oxides. He explored the compositional and structural principles of fluorite-related oxygen-deficient non-stoichiometric rare earth higher oxides, RO2-d (0= d =1) (R=Ce, Pr, Tb) (Kang-Eyring module theory) and its applications in green energy technology such as the redox catalysis and hydrogen production by temperature swing with methane and water cycling. Recently he is interested in the relationship between the mysterious properties of functional oxides, containing rare earth and transition metal elements, and the degree of quantum freedom. He published patents, and books, more than 100 papers:

After he retired, he learns and search what is the transmission electron microscopy and what is an electron and why I could not use the high-resolution electron microscopy to solve the oxygen vacancies distribution in the fluorite-related oxygen-deficient non-stoichiometric rare earth higher oxides. The questions had haunted him in long time, However, a recent paper of professor A. Howie said that "In his (Ruska's) Nobel prize acceptance speech, Ernst Ruska admitted that he became aware of the wave properties of the electron only as late as 1931 when he had already made his invention" and the success of the modern electron microscopy is based on the wave imaging technology. The transmission electron microscopy forth would be made by "continued skirmishing on the wave-particle frontier". He has spend almost 5 years to write this book in the memory of Professor Leroy Eyring and John W. Cowley.
