A Transmission Electron Microscope (TEM) is a kind of electron microscope that images by detecting electrons that pass through a sample (hence, the tranmission). This requires both very thin samples and much higher electron kinetic energies, at least an order of magnitude greater than a conventional Scanning Electron Microscope (SEM). If a particular TEM operates with an accelerating voltage of 150 kV, and therefore electrons with kinetic energies of 150 keV (recall KE = q∆V ), calculate the theoretical smallest...
