View Presentation Abstract
In this talk, I will present the spin and charge conversion using the topological surface states and Rashba-split 2DEG. In the first one , I will describe our experimental results that demonstrate the spin injection and the inverse Edelstein effect in the spin-momentum locked surface states of a topological Kondo insulator, SmB6. I will also discuss the spin pumping efficiency between the topological surface states and a ferrimagnetic insulator (YIG) due to interfacial s-d exchange interaction. In the second part of my talk , I will discuss the gate-tunable the inverse Edelstein effect up to room temperature in the Rashba-split 2DEG between SrTiO3 and LaAlO3 .
