Abstract: Metal oxide nanomaterials have important applications in energy efficient electronics and energy storage devices because of their unique semiconducting/dielectric properties. However, attempts to assemble these nanoscale objects into sophisticated structures, nanoelectronics, and nanodevices have been largely unsuccessful. In this work, we have developed effective approaches to well-organized metal oxide nanostructures and devices by using self-assembly technology. For example, self-assembled dielectric oxide nanocubes have been fabricated and their superior electrical properties for random access memories have been demonstrated. Besides, a novel type of supercapacitor devices has been proposed based on graphene paper/oxide semiconductor nanocrystals hybrid structure.

Biography: Dr. Dewei Chu received a PhD degree in Materials Science from Chinese Academy of Science in July 2008. He joined National Institute of Advanced Industrial Science and Technology (AIST), in Japan, from July, 2008 to October, 2010. In November, 2010, Dr Chu received a competitive research grant (~$\$$140,000) from Japan Society for the Promotion of Science (JSPS), and then worked as a JSPS postdoctoral fellow. In April, 2011, Dr Chu joined School of Materials Science & Engineering, the University of New South Wales as an Australian Postdoctoral Fellow (APD). Currently Dr Chu directs the Research Group for Nano-multifunctional Materials that consists of 7 researchers, including 3 PhD students, 2 Master degree students and 2 honours students. In the past four and half years since graduating with his PhD, Dr Chu has succeeded in sustaining funding to support his research to the value of $1,130,000 as first CI.
