PLD (Pulsed Laser Deposition) is suitable to grow complex oxides thin films with accurate control of stoichiometry and thickness. Thus, traditionally, high quality complex oxides thin films synthesized using PLD have been used as a key material to develop the oxide electronics to overcome the limit of Si-based electronics. Recently, in the field of not only oxide electronics, but also advanced energy application such as solar energy conversion, complex oxides thin films have gained much attention due to their novel properties. We present several examples about the studies to engineer the electrical, morphological properties of oxide thin films for better performance in energy application. First topic is about ferroelectric domain-controlled BiFeO3 thin films via crystallographic orientation-controlled growth which resulted in enhanced photocatalytic efficiency. Second topic is about morphology-controlled BiVO4 thin films to enhance the photocatalytic effect. We believe that these various studies about “advanced oxide energetics” could expedite the realization of eco-friendly and sustainable energy harvesting. |
