Query: Quantitative atom counting of Zn and O atoms by atomic resolution
  off-axis and in-line holography   Quantitative atom counting of Zn and O atoms in zinc oxide(ZnO)epitaxial thin
film by three different routes; reconstruction of phase from side and central
band of atomic resolution off-axis and in-line electron holography are
presented. It is found that the reconstructed phase from both side and central
band and corresponding atom number for both Zn (Z = 30) and O (Z = 8) atom
columns are in close agreement along with the systematic increase in thickness
for thinner sample area.However, complete disagreement is observed for the
thicker sample area. On the other hand,the reconstructed phase obtained via
in-line holography shows no systematic change with thickness.Phase detection
limits and atomic model used to count the atoms are discussed.
