Project title: Spin to charge conversion phenomena in 2DEG at the oxide interfaces
My research project focuses on the fabrication and characterization of high-mobility two-dimensional electron gas (2DEG) systems at complex oxide interfaces, which exhibit strong Rashba spin–orbit coupling. These oxide heterostructures provide a versatile platform for exploring spin-to-charge conversion phenomena, a key mechanism in the development of energy-efficient spintronic devices. The study will employ a combination of experimental techniques, including magneto-transport measurements to probe carrier dynamics under magnetic fields, and ferromagnetic resonance (FMR) spin pumping to inject pure spin currents into the 2DEG and detect their conversion via interfacial effects such as the inverse spin Hall or Rashba-Edelstein effect. By leveraging the tunable properties of oxide interfaces and their strong interfacial spin–orbit interactions, this work aims to advance the fundamental understanding of spin–orbitronics and contribute to the development of novel spin-based memory and logic technologies.
