Abstract :
High electric fields were delivered to specimens during imaging in the transmission electron microscopy (TEM) chamber to reveal details of electric field-induced phenomena in ferroelectric oxides. These include the grain boundary cavitation in a PZT ceramic, the domain wall fracture in a Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT) single crystal, the transformation of incommensurate modulations in Pb0.99Nb0.02[(Zr1-xSnx)1-yTiy]0.98O3 (PZST100x/100y/2) ceramics, and the growth of polar nanodomains in a Sc-modified PMN ceramic.
