Spintronics, which exploits the spin of electrons for information processing, holds great potential advantages of speeding up data processing, high circuit integration density, and low energy consumption. To obtain high performance spintronic devices, there are still several challenges ahead, including spin-polarized carrier injection, long-distance spin transport, and effective manipulation and detection of the carriers’ spin orientation. The solutions to these problems lie in designing new materials with specific spintronic properties, such as magnetic semiconductors and half metals. Meanwhile, by virtue of computational simulations, the properties of existing materials or even hypothetical materials can be routinely predicted, based on which one can pick out those with required properties, and confirm them further by experiment. Such a procedure can largely improve the efficiency of materials design.
In this lecture, the speaker will focus on theoretically designing spintronic materials with special functions, and exploring spintronic materials that can work at room temperature, paving the way for eventual realization and application of spintronic devices.
About the speaker
Prof Jinlong Yang received his MS in Solid State Physics and PhD in Condensed Matter Physics from University of Science and Technology of China (USTC) in 1988 and 1991 respectively. He furthered his career in USTC as a lecturer subsequently and is currently the Changjiang Professor. Prof Yang is also the Head of Division of Theoretical and Computational Sciences of the Hefei National Laboratory of Physics Sciences at the Microscale.
Prof Yang’s research focuses on density-functional theory and time-dependent density-functional theory studies of atomic clusters; scanning tunneling microscope image and dI/dV mapping simulation; theoretical studies on nanotubes; transport properties of molecular devices; electronic structure of novel surfaces and bulk materials; and new computational methods and codes.
Prof Yang received the Chinese National Young Science and Technology Award in 2006 and was elected Fellow of the American Physics Society in 2011. He also served as an editorial board member for some renowned journals including the Theoretical Chemistry Account and Physical Review X.
