Abstract:

The discovery of novel materials has often propelled progress and breakthroughs in IT industries, which change our everyday lives. Since the discovery of giant magnetoresistance (GMR) effect in metallic nanoscale multilayers (Nobel Prize in Physics, 2007), the first-generation spintronics has already generated huge impact to the mass data storage industries. The next-generation spintronics, on the other hand, focuses on the integration of the magnetic and semiconductor materials and so to add new capabilities to the future energy efficient and fast microelectronics/nanoelectronics. In this talk, I will report recent progresses of the research on a selection of hybrid nanomaterials including those based on ferromagnetic metal (FM) and alloys, half-metallic materials and two-dimensional (2D) materials. FM and alloys have spontaneous magnetization and usually high Curie temperature (Tc), half-metallic materials possess high spin polarization near the Fermi level (EF), and the 2D materials have unique band structures such as the Fermi Dirac cone and valley degree of freedom of the charge carriers. Enormous progress has been achieved in terms of synthesizing the epitaxial hybrid spintronic materials and revealing their new structures and properties emerging from the atomic dimensions and the hetero-interfaces. Apart from the group-IV, III-V and IIVI semiconductors and their nanostructures, spin injection and detection with 2D nanomaterials such as graphene, transitionmetal dichalcogenides (TMDs) and topological insulators (TIs) has become a new trend and a particularly interesting topic due to either the long spin lifetime or strong spin-orbit coupling induced spin-momentum locking, which potentially leads to dissipationless electronic transport.
