Using a TV Set to Show Electron Diffraction

We show the feasibility of constructing a simple set-up to demonstrate the diffraction of electrons starting from a standard TV set. Two concentric rings around a central maxima appears on the screen of the modified TV set corresponding to atomic planes (1, 0, 0) and (1, 1, 0) of a hexagonal structu...
