Abstract

A multi-field coupling structure is designed and investigated, which combines GaN-based optoelectronic devices and Terfenol-D. The abundant coupling effects and multifunctionalities among magnetics, mechanics, electrics, and optics are investigated by a combination of non-magnetic GaN-based piezoelectronic optoelectronic characteristics and the giant magnetomechanical properties of Terfenol-D. A few potential new areas of studies are proposed.
