Second harmonic generation in multiferroic BaTiO3-BiFeO3 film and nanorod arrays grown on Si substrate

The increasing demands for device miniaturization toward energy efficient electronic, optoelectronic, and spintronic applications have led to the advancement of novel material systems such as multiferroics. In this study, we investigated nonlinear optical responses of a (0.275)BaTiO₃-(0.725)BiFeO₃ (BTO-BFO) film and a nanorod arrays, grown on Si substrates. Our results are important for employing these materials for new and improved optical applications.
