abstract = {On the basis of a state-of-the-art aberration-corrected
transmission electron microscope, the spherical aberration
coefficient C S of the objective lens can be tuned to either
a positive or a negative value. The use of a negative value
of C S combined with an overfocus setting of the objective
lens leads to the development of the negative C S imaging
(NCSI) technique. Images obtained using the NCSI technique
show superior contrast and signal intensity at atomic column
positions than the corresponding positive C S images,
especially for weakly scattering oxygen columns that are in
close proximity to strongly scattering cation columns in
oxides. Based on the images obtained under the NCSI
condition, quantification of the image contrast allows
measurements of the atom positions with a precision of a few
picometers and the local chemistry on atomic scale. In the
present review, we discuss firstly the benefits of the NCSI
technique in studies of oxide materials, and then show a
procedure for quantitative analysis of the image based on
the absolute value of contrast. In the last part, examples
are given for the application of the quantitative
high-resolution transmission electron microscopy (HRTEM) to
the study of electric dipoles of oxide ferroelectrics and
atomic-scale chemistry of interfaces.},
