Abstract

In this talk I will show how the Rashba spin-orbit coupling present in two-dimensional electron gases (2DEGs) based on SrTiO3 can be used to interconvert spin and charge currents with great efficiency. The conversion is highly tuneable by gate voltages, as the Fermi level is displaced across the complex multi-orbital band structure of the 2DEG. These results offer possibilities for device applications, for instance into Intel's MESO transistor. Finally, I will present a new ferromagnet-free approach to achieve a non-volatile control of spin-charge interconversion with ferroelectric Rashba 2DEGs, that may pave the way to an entirely new family of ultralow power spintronics device.
