초록:
This talk will cover the functionalities of nanostructured oxide materials composed of ubiquitous elements, specially the electro-active functionalities of both natural and artificial nanostructured oxide. It is well-known in the college textbook that the abundant light-metal oxides such as SiO2, Al2O3 and CaO are typical insulators exhibiting no electro-active functionalities. However, this common sense should be revised to that “Nanostructured light-metal oxides show the electrical conduction from semiconducting to metallic and finally to superconductivity.” This phenomenon is based on the interstitial electrons in a structural space with the size of nanoscale, which have a long history over 2 century, from the birth of solvated electrons discovered in 1806 to the recent discovery of electride materials.
