Abstract
Spintronics and Quantum Electronics are emerging as candidates for future high performance computing and information processing platforms. In this realm, computation is performed through new operational concepts, as for instance the use of the electron spin,rather than charge, as information carrier, or through the radically different principles of quantum computation, implemented by manipulation of quantum bits (qubits).Recent developments in these fields showed that the exploitation of the Rashba Spin Orbit Coupling (SOC) in two-dimensional 2D materials is an innovative and attractive solution in both spintronic and quantum computation. The exploration of Rashba physics is now at the heart of the growing research field of spin-orbitronics, a branch of spintronics that focuses on the manipulation of non-equilibrium material properties using SO coupling. For example, SOC is used for a more efficient charge to spin conversion in spin-orbit torque (SOT) devices compared to classical devices. On the same ground, the exploitation of the Rashba SOC in spin-orbit and topological qubits may lead to the realization of quantum computers intrinsically less sensitive to external perturbation.
Obiettivi
Instrumental to the realization of novel Spintronics and Quantum Electronics systems is the design of a single-material platform which shows simultaneously magnetism, superconductivity, gate-voltage switchable superconductivity, and large and gate tunable Rashba SOC. 2D electron gases (2DEGs) formed at the interface between transition metal oxides, like LaAlO3 and SrTiO3, are promising candidates for the realization of electric field controlled spin-orbitronic devices. Oxide 2DEGs are indeed characterized by a unique combination of high-mobility , strong spin-orbit coupling (SOC), superconductivity (SC), interfacial 2D-magnetism, and theoretically predicted topological states . These characteristics result in the possibility to finely adjusts the oxide functional properties, through material design and engineering, and to realize nano-devices entirely controlled by gate voltages. Success in these endeavors will open the road towards a novel oxide electronics and will establish 2D-oxide materials as an important platform for spintronics and quantum electronics.
