报告摘要：The talk will first give a brief overview of the energy challenge of today’s CMOS scaling. Then I will describe the advantages and impact of magnetic devices in terms of its low switching energy, high speed, high endurance, and scalability. The physics of spin transfer torque (STT) will be described for its application of spintronic memory. Next, we will describe in addition the physics of spin-orbit interaction and spin Hall to improve energy efficient switching via polarized spins. we will also describe a couple of fundamental mechanisms of voltage control of magnetic moment and direction at the metallic surface. Additionally the recent progress in using spin Hall to produce large torque for further reducing energy in switching nanomagets will be discussed. Further advances are possible by adopting the spin wave bus concept -- the use of spin waves for logic and interconnect. With low energy, high density memory and spin wave bus, it may be possible to construct a new type of neuromorphic information processing electronics. These types of devices may be integrated directly on top of front-end processed CMOS to enable new generations of nonvolatile instant-on electronics and other systems. A potential new paradigm of intelligent nano-systems may emerge.
