报告内容简介:During the last decade, the spintronics based on spin-orbit coupling (SOC), the so-called spin-orbitronics, where the generation, manipulation and detection of spins are realized by all electrical means, has aroused great interest. The SOC in a solid without inversion symmetry is characterized by the spin splitting of electronic bands and specific spin texture-spin arrangement in momentum space. In this talk, I will first discuss the nature of spin texture governed by the point group symmetry. In particular, I will focus on the persistent spin texture, which preserves the SU(2) spin rotation symmetry and renders an ultimately infinite spin lifetime, and spin-textured ferroelectrics, where SOC leads to an intrinsic link between spin texture and electric polarization, with the appealing perspective of electric-field control of spin. Second, I will discuss two novel spin-orbitronic devices i.e. valley-spin valve and valley-spin logic gate, which utilizes the electric control of spin.
