Abstract
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.
