| Research Abstract |
Using environmentally benign transparent oxide semiconductors, we have created clean two-dimensional electron systems and succeeded in observing field-effect induced superconductivity and the fractional quantum Hall effect. These phenomena are originated from Coulomb interaction between quantized complex particles and thereby can potentially be applied for a basic element of completely new computer architectures. The materials used in this study exhibits exceptionally strong Coulomb interaction, compared with conventional semiconductors, presenting promising opportunities to find oxide semiconductors more exotic than ever in condensed matter physics.
