Re. Duninborkowski et Wo. Saxton, THE ELECTROSTATIC CONTRIBUTION TO THE FORWARD-SCATTERING POTENTIAL ATA SPACE-CHARGE LAYER IN HIGH-ENERGY ELECTRON-DIFFRACTION .2. FRINGINGFIELDS, Acta crystallographica. Section A, Foundations of crystallography, 53, 1997, pp. 242-250
The electrostatic potential is determined both inside and outside a pa
rallel-sided dielectric slab that contains a space charge layer whose
plane is perpendicular to the surfaces of the slab, with particular re
ference to the use of phase-contrast techniques in transmission electr
on microscopy to characterize such layers.
