Bismuth ferrite (BFO) thin films demonstrate a range of properties, including giant polarization and high piezoelectric constant that make them particularly attractive candidates for lead-free memory storage and piezoelectric devices. Peggy’s recent work, published in the Journal of Materials Chemistry C (Vol. 3, p582), has shown that high quality epitaxial BFO films with robust ferroelectric properties can be delivered via chemical solution deposition: metal nitrates form the basis of a homogeneous gel from which BFO films are crystallised. A bulk chemical process of this type offers significant potential for large scale, low cost commercial production of BFO films.
Peggy made use lithography and metal deposition tools in the ANFF-NSW laboratories to create electrodes on the BFO films, enabling electrical characterisation studies to be conducted.
