Nanomaterials and Nanotechnology
International Conference on
Hybrid nanomaterials for the next generation energy efficient spintronics
Yongbing Xu
Nanjing University, China
T
he 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 themass 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 andproperties emerging fromthe atomic dimensions
and the hetero-interfaces. Apart from the group-IV, III-V and II-
VI semiconductors and their nanostructures, spin injection and
detection with 2D nanomaterials such as graphene, transition-
metal 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.
Speaker Biography
Yongbing Xu, director of the Nanjing-York Joint Center in Spintronics and Nano Engineering,
Nanjing University, China; chair in Nanotechnology, also heads the Spintronics and
Nanodevice Laboratory, The University of York. He was an EPSRC advanced research
fellow in Cavendish Laboratory, Cambridge University. His research interests are in the
areas of nanomaterials, spintronics and nanofabrication. He has published more than
300 refereed papers in leading academic journals including physical review letters,
nature communications, nano letter, advanced materials, ACS nano, scientific reports,
applied physics letters and IEEE journals and given many invited talks/seminars at major
international conferences including MRS, WUNSPIN, EMN and Intermag. He was editor-in-
Chief of “Handbook of Spintronics” by springer and edited the very first spintronics book
“Spintronic Materials and Technology” by CRC Press. He had interviews with BBC News24
and new scientists.
