Abstract
A light emitting device with magnetic field includes a light-emitting structure and a first magnetic-source layer. The light-emitting structure includes a first doped structural layer, a second doped structural layer, an active layer between the two doped structural layers, a first electrode, and a second electrode. The first magnetic-source layer is integrated with the light-emitting structure to produce a magnetic field in the light-emitting structure. The magnetic field transversely shifts a driving current of the light-emitting structure to redistribute in the light-emitting structure.
