Oxides hold the great promise for emerging electronic applications (other than conventional CMOS components such as gate oxides) because they can significantly increase the operational range of temperature and bias voltage due to the much higher bandgap energy than semiconductors. However, using the oxides for such novel purposes requires their electronic properties to be properly tuned and tailored to specific device applications. Therefore, this work seeks to develop the way to address this challenge by focusing on the tunable characteristics of perovskite oxides driven by their unique electromechanical and electrothermal couplings. Among various types of oxides, crystalline perovskite titanate structures such as STO (SrTiO_3) have been chosen as the representative material platform in this study, due to their multifunctional properties and well-established growth techniques.
