WIPO Patent Application WO/2018/165910
Kind Code:
A1
Abstract:
Disclosed is a porous gallium nitride single crystal material, characterized in that the porous gallium nitride single crystal material contains pores with sizes ranging from 10 nm to 2000 nm. The material has a self-supporting structure, and where same is a bulk single crystal, the material serves as an epitaxial substrate for a gallium nitride-based device, and can serve the function of stress relief and dislocation annihilation, and is more advantageous than non-porous gallium nitride single crystal substrates. Moreover, the material can also provide a high-quality template for 3D optoelectronic devices.
