报告人简介：
Dr. Ron Jansen received a PhD in Experimental Physics from the University of Nijmegen (The Netherlands) in 1997, and was a postdoctoral associate at the Massachusetts Institute of Technology (MIT, Cambridge, USA). After that he moved to the University of Twente (The Netherlands), where he became a tenured assistant professor, associate professor, leader of the NanoElectronics Research Chair and group leader with the Netherlands Foundation for Fundamental Research on Matter (FOM). Since 2010, he works at the National Institute of Advanced Industrial Science and Technology (AIST, Tsukuba, Japan), where he is now a prime senior researcher (首席研究員) at the Spintronics Research Center. He has published 100+ technical articles in peer-reviewed journals, incl. book chapters and reviews, and given more than 110+ invited scientific presentations.

报告摘要:
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.
