Extrinsic Orbital Hall Effect and Orbital Relaxation in Mesoscopic Devices
The study investigated how disorder affects orbital transport in mesoscopic devices using a tight-binding model of atomic orbitals. It found that disorder enhances the Orbital Hall Effect (OHE) via skew scattering in square devices, while orbital current decays exponentially with width in rectangular ones, allowing calculation of the orbital relaxation length. This provides insights for designing orbitronic devices.
