Abstract

Leakage current behavior of (BiFeO₃)_m(SrTiO ₃)_m superlattice structures was studied and analyzed at different temperatures (303-473 K) 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 ∼0.06-0.25 eV was calculated. The physical parameters, calculated from the analysis, correlate with the intrinsic properties. Such analysis of leakage current facilitates interface engineering of heterostructures for device applications. © 2008 American Institute of Physics.
