dc.descriptionLeakage current behavior of (BiFeO3)m(SrTiO3)m superlattice structures was studied and analyzed at different temperatures (303-473K) in the light of various models. While bulk limited Poole-Frenkel emission was observed to dominate the leakage current in the temperature range of 303 - 383 K, the space charge limited conduction was observed up to 473 K. With a Poole-Frenkel emission type of conduction, the activation energy range of 0.06 - 0.2 eV was calculated. The physical parameters, calculated from the analysis correlates with the intrinsic properties. The analysis of leakage current facilitates, interface engineering of heterostructures for device applications.
