Near-Field Spin Seebeck Effect
Abstract
The conventional spin Seebeck effect generates spin currents through interfacial thermal conduction. In this Letter, we establish a photon-mediated spin Seebeck effect driven by near-field thermal radiation. Using a monolayer transition metal dichalcogenide separated from a thermal emitter by a vacuum gap, we demonstrate Rashba spin-orbit coupling can convert optical orbital excitations into an electron spin polarization. This occurs via two complementary mechanisms: the direct transfer of angular momentum from chiral thermal photons, and the rectification of unpolarized thermal fluctuations by a magnetized two-dimensional electron gas. These findings unveil a radiative pathway for nanoscale electron spin manipulation.
