Abstract
In a topological insulator (TI), spin-charge conversion (SCC) is expected to occur at the surface through the spin-momentum locking of the metallic surface states. MBE-grown TIs however are oftentimes unintentionally doped resulting in bulk states that can convert spin to charge through the inverse spin hall effect. In this work, we investigate the SCC mechanisms of the TI Bi2Se3 using time-resolved THz emission spectroscopy. Here, we demonstrate THz emission in NiFe/Bi2Se3 heterostructures using bulk-insulating Bi2Se3 and bulk-conducting Bi2Se3. We also present results comparing NiFe/Bi2Se3 to W/NiFe/Pt, a heavy metal spintronic THz emitter.
