Abstract :
High electric fields were delivered to specimens during imaging in the transmission electron microscopy (TEM) chamber to reveal details of electric field-induced phase transitions in ferroelectric oxides. These include the growth of polar nanodomains in a Sc-modified Pb(Mg1/3Nb2/3)O3 ceramic and the R3c to R3m phase transition in a 0.02% Nb-doped Pb(Zr0.95Ti0.05)O3 ceramic.
