HR-TEM Studies of FePt Nanoparticles by Exit Wave Reconstruction

Zeitschriftenaufsatz / Fach: Physik
Direct imaging of the lattice structure of 2 to 6 nm sized nanoparticles is often disturbed by delocalization effects. FePt nanocrystals were investigated carrying out a direct reconstruction of the phase and the amplitude of the scattered electron wave from a focal series of HR-TEM images, resulting in a determination of the layer-resolved structure with sub Ångstrom resolution.
