<p><span lang="EN" style="font-size:11.0pt;font-family:"Georgia","serif"">Worldwide efforts are underway to create a revolutionary and energy-efficient information technology in which digital data is represented by the spin orientation of electrons. Implementing
spin functionality in silicon, the mainstream semiconductor, has the potential to create broad impact. Remarkable advances in the creation and control of spin polarization in silicon have therefore generated much excitement. This lecture provides a transparent
picture of silicon spintronics, including the key developments and achievements, our current understanding, as well as the unsolved puzzles and challenges that stimulate researchers in the field.<o:p></o:p></span></p>
<p><span lang="EN" style="font-size:11.0pt;font-family:"Georgia","serif"">First, the basic idea of spin-based information technology and silicon spintronics is introduced. Ferromagnets have non-volatile memory functionality, whereas semiconductors provide
amplification and transistor action. What if we integrate ferromagnets and silicon — magnetic memory and logic computing? Then the main building blocks are described: one needs to be able to create spin polarization in the silicon, to manipulate it, and thereafter
detect the spins. The generation of a spin flow by electrical means (driven by a bias voltage) or thermal means (driven by a heat flow) are discussed. Ferromagnetic tunnel contacts are shown to provide a robust method to do this, at room temperature. The lecture
concludes with a prospect on future developments, which certainly includes more surprises as silicon spintronics comes of age.<o:p></o:p></span></p>
<p><span lang="EN" style="font-size:11.0pt;font-family:"Georgia","serif"">Thank you,<o:p></o:p></span></p>
