Abstract
Disclosed is a method of fabricating a gallium nitride substrate using nanoparticles with a core-shell structure. A method of fabricating a gallium nitride substrate using nanoparticles with a core-shell structure according to an embodiment of the present disclosure includes a step of coating nanoparticles with a core-shell structure on a temporary substrate to form at least one nanoparticle layer; a step of allowing a pit gallium nitride (pit GaN) layer to grow on the temporary substrate; a step of allowing a mirror GaN layer (mirror GaN) to grow on the pit GaN layer; and a step of separating the temporary substrate, wherein each of the nanoparticles with a core-shell structure includes a core and an ionic polymer shell coated on a surface of the core surface.
