The study of the GaN micro-rod selective area growth morphology depends on the buffer layer by MOCVD |
초록 |
Recently, the researchers who had studied about LED, have attempted to fabricate small size of LED under micro diameter or different shape of LED. There are two methods to fabricate the rod shape of LED: top-down and bottom-up. The bottom up method has advantage of no damage and high quality of crystalline even though this method is quite difficult to epi-growth. This is the first step of study of GaN micro-rod epi-growth, the GaN micro-rod are grown with selective area growth by MOCVD on the patterned sapphire substrate. From the kind of the buffer layer on the polished PSS, we can figure out the GaN micro-rod morphology depends on the buffer layer. The GaN morphology was analyzed through a scanning electron microscope and the polarity was analyzed by KOH etching. |
