To increase the efficiency of microchips, 3-D structures are now being investigated. However, spintronic components, which rely on electron spin rather than charge, are always flat. To investigate how to connect these to 3-D electronics, University of Groningen physicist Dr. Kumar Sourav Das created curved spin transport channels. Together with his colleagues, he discovered that this new geometry makes it possible to independently tune charge and spin currents. The results were published online by the journal Nano Letters on 13 September 2019.
