Possible absence of critical thickness and size effect in ultrathin perovskite ferroelectric films
Understanding ferroelectricity at reduced dimensions will be important for future sub-nanoscale devices based on ferroelectrics. Using high resolution electron microscopy; Gaoet al., observe the existence of a measurable polarization at a thickness of just 1.5-unit cells
