Abstract
Hollow-cone illumination in the electron microscope improves significa ntly the resolution in the images of thin crystalline specimens. Optim um imaging parameters are obtained by maximizing the central contrast of a weak point scatterer. The gain in resolution is demonstrated by m eans of simulated images of silicon in [110] orientation (dumbbell str ucture) and of YBa2Cu3O7 in [100] orientation.
