Due to the inherent nature of a large interface area of nanocomposite systems, there exists a strong coupling strength, which can generate new physical properties in our designed systems. Here, the main topics will be focused on (1) hybrid high K materials/GaAs two-dimensional electron gas (2DEG) (2) hybrid Al nanofilm/GaAs 2DEG (3) hybrid iron-based superconductor/GaAs 2DEG (4) hybrid magnetic film and nanoscale compound semiconductors (5) hybrid graphene and nanoscale compound semiconductors. We will investigate probably the most frontier nanocomposite materials in the world, which combine the interesting nanomaterial systems with low dimensional electron systems. We believe that we will be able to observe unique physical effects and may answer some important issues, such as coupling between hybrid nanosystems, transport mechanism of low dimensional systems, and magneto-electric effect at room temperature, and so forth. They will be very useful to create high performance and green devices.界面高介電材料複合奈米半導體材料耦合機制砷化鎵低維度電子系統傳輸機制。interfacehigh K materialshybrid semiconductor nanomaterialscoupling mechanismGaAs low dimensional electron systemstransport mechanism.
