Large spin splitting at Rashba interface, giving rise to strong spin-momentum locking, is essential for efficient spin-to-charge conversion. Recently, a Cu/Bismuth oxide (Bi 2 O 3 ) interface has been found to exhibit an efficient spin-to-charge conversion similar to a Ag/Bi interface with large Ras...
