The study of GaN-based semiconductors with low-defect density by microstructural characterization
미세구조 분석을 이용한 저밀도 결함을 가진 GaN계 반도체 연구
Abstract
We have investigated the microstructural analysis of epitaxial lateral overgrowth (ELO), pendeoepitaxy (PE), and superlattice structures used as technology for the reduction of structural defects like dislocation in nitride semiconductors using transmission electron microscopy. We confirmed that the regrowth process such as ELO and PE is very effective technique on the reduction of threading dislocation (less than
