4. 제 목 : Oxide nanostructures on demand
Metal oxides have a wide variety of applications including electronic devices, energy conversion and storage devices, and sensors. For electronic applications, electronic confinement at nanoscale dimensions remains a central means of science and technology. For energy and environmental applications, tremendous efforts have been devoted to synthesize metal oxide nanomaterials with large specific surface areas. Thus, the control and tuning of the morphology and structure of metal oxides at nanoscale is of great importance for improving the performance of devices based on metal oxides. With a brief review on multiferroicity of BiFeO3, ferroelectricity in SrTiO3, high mobility 2-dimentional electron gas (2DEG) at oxide heterointerfaces, and semiconducting metal oxides for gas sensors, I will show how we could manipulate nanostructures of the various oxide material systems and subsequently enhance (or tune) the electrical properties of the materials and devices, which suggests that our on-demand oxide nanostructure platform has the potential for widespread technological applications.
