Diffraction refers to the apparent bending of waves around small objects and the spreading out of waves past small apertures. In our context Electron Diffraction. Do moving electrons display wave nature? To answer this question you will direct a beam of electrons through a thin layer of carbon and analyze the resulting pattern. Theory. Louis de Broglie originated the idea that moving electrons may exhibit both particle and wave nature. He proposed that Electron Diffraction. A. Principles of Diffraction. Diffraction is the spreading of waves around obstacles. One consequence of diffraction is that sharp shadows are not produced. The phenomenon is most pronounced when the wavelength of the radiation is comparable to the linear dimensions of the obstacle. When a beam of This guide sheet outlines a method for the analysis of cubic crystal forms, this being useful to you for interpreting the transmission diffraction pattern produced by scattering electrons off a thin film target of polycrystalline aluminium. The apparatus also contains samples with hexagonal structures. These are pyrolytic graphite 9 Feb 2006 where p is the momentum, ? is the wavelength, and h is Planck's constant h = 6.626 10 34 J s = 4.136 10 15 eV s . To observe wave-like behavior, we require some kind of grating where the “distance between slits" is of order the wavelength. At typical laboratory energies, the electron's de Broglie determination at the scale of a few nm are well known. In practice, the approach is often limited due to the restriction on the angular range of the electron beam imposed by the small. Bragg angle for high energy electron diffraction, i.e. a large convergence angle of the incident beam results in overlapping information in the In this equation, h is Planck's constant and E = p2/(2m) is the kinetic energy of the particle in the non-relativistic regime. The wave aspect of particles was demonstrated first by an experiment on electron diffraction performed by C. H. Davisson and L. H. Germer. For his hypothesis on t$
