abstract = {Computer simulations are used to assess the influence of a
20-nm-thick SiNx membrane on the quantification of
atomic-resolution annular dark-field (ADF) scanning
transmission electron microscopy images of Pt nanoparticles.
The discussions include the effect of different
nanoparticle/membrane arrangements, accelerating voltage,
nanoparticle thickness and the presence of adjacent atomic
columns on the accuracy with which the number of Pt atoms in
each atom column can be counted. The results, which are
based on the use of ADF scattering cross-sections, show that
an accuracy of better than a single atom is attainable at
200 and 300 kV. At 80kV, the scattering in a typical SiNx
membrane is sufficiently strong that the best possible atom
counting accuracy is reduced to +/- 2 atoms. The
implications of the work for quantitative studies of Pt
nanoparticles imaged through SiNx membranes are discussed.},
