Figure 4
SAED patterns (upper row) and the corresponding HAADF-STEM images (lower row) for three members of the (Pb,Bi)1 − xFe1 + xO3 − y family with different concentration of Bi (i.e. different degree of anion deficiency that depends on the Pb2+/Bi3+ ratio): (a,b) 10 at.%, (c,d) 30 at.% (e,f) 56 at.% of Bi in the A cation sublattice. |
