Light elements like carbon may enter unintentionally into a material during material processing owing to their ubiquitous nature, and may significantly influence its observed electronic and magnetic properties. In the present work, the energetics and kinetics of carbon impurity related defects in BiFeO3 (BFO) are studied using first principles calculations in order to gain insight into the ongoing controversial aspects of conductivity of BFO. The results suggest that oxygen deficient conditions provide a favorable chemical environment
