Abstract
An ultrathin (6.2 nm) ferroelectric La<sub>0.1</sub>Bi<sub>0.9</sub>FeO<sub>3</sub> (LBFO) film was epitaxially grown on a 0.7 wt% Nb-doped SrTiO<sub>3</sub> (001) single-crystal substrate by carrying out pulsed laser deposition to form a Pt/La<sub>0.1</sub>Bi<sub>0.9</sub>FeO<sub>3</sub>/Nb-doped SrTiO<sub>3</sub> heterostructure.
