abstract = "Discovering dielectric materials with large flexoelectric coefficients is key to advancing electromechanical devices. Using first-principles calculations, we determine the longitudinal and transverse flexoelectric coefficients of perovskite superlattice materials composed of ATiO3 (A=Pb, Ba, Sr). Our results show that the longitudinal flexoelectric coefficients of these superlattices are approximately four times larger than those of their parent bulk materials, respectively. This enhancement in the flexoelectric effect is attributed to charge transfer and interfacial interactions, which strongly influences the polarization in perovskite superlattice systems. These results can provide a guidance for searching for composite materials with large flexoelectric coefficients.",
