Abstract/OtherAbstract:
A time-resolved acquisition technique for elemental mapping has been investigated for the heavy element barium (Ba) in (Ba(0.5), Sr(0.5)TiO3 (BST) by energy-filtering transmission electron microscopy (EF-TEM). Based on the conventional three-window method, five images were separately acquired for each energy region (about 780 eV signal region, and pre-1 and pre-2 energy regions). After correcting for image shift, the five images were added to form a new processed image in each energy region. Then, Ba element mapping was performed by using the conventional three-window procedure. This time-resolved technique was found to improve signal-to-noise ratio for 100 s total exposure time without increasing the image blurring problem.
