摘要:
Methods of growing nitride semiconductor layers including forming nitride semiconductor dots on a substrate and growing a nitride semiconductor layer on the nitride semiconductor dots. The nitride semiconductor layer may be separated from the substrate to be used as a nitride semiconductor substrate.
摘要:
A method of manufacturing a large area gallium nitride (GaN) substrate includes forming a buffer layer on a silicon substrate, forming an insulation layer pattern on a rim of a top surface of the buffer layer, growing a GaN layer on the buffer layer, and removing the insulation layer pattern and a portion of the GaN layer and the silicon substrate.
摘要:
A method of growing a nitride semiconductor layer includes forming a plurality of nano-structures on a substrate, forming a first buffer layer on the substrate such that upper portions of each of the nano-structures are exposed, removing the nano-structures to form voids in the first buffer layer, and growing a nitride semiconductor layer on the first buffer layer including the voids.
摘要:
A nitride semiconductor device includes a dislocation control layer on a substrate, and a nitride semiconductor layer on the dislocation control layer. The dislocation control layer includes a nanocomposite of a first nanoparticle made of a first material and at least one second nanoparticle made of a second material.
摘要:
A method of growing a nitride semiconductor layer may include preparing a substrate in a reactor, growing a first nitride semiconductor on the substrate at a first temperature, the first nitride semiconductor having a thermal expansion coefficient different from a thermal expansion coefficient of the substrate, and removing the substrate at a second temperature.
