Description
1998년 5월 29일 공개된 일본 공개 번호 제10145006호 (출원번호 제09206362호; 1997년 7월 31일)에는 wurtzite 타입의 실리콘 카바이드(SiC), 알루미늄 갈륨 나이트라이드(AlGaN)와 실리콘 카바이드의 혼합 결정 전이층, n-타입의 알루미늄 갈륨 나이트라이드 층, 도핑되지 않은 갈륨 나이트라이트(GaN) 층, 인듐 갈륨 나이트라이드(InGaN) 활성층, 도핑되지 않은 갈륨 나이트라이트 층, p-타입의 알루미늄 갈륨 나이트라이드 층, 및 p-타입의 갈륨 나이트라이드 층을 포함하는 반도체 레이저가 기재되어 있다. 상기 전이층은 격자 상수의 차이를 완화시키고, 실리콘 카바이드 기판과 n-타입의 알루미늄 갈륨 나이트라이드 층 사이에 있는 실리콘 카바이드와 알루미늄 갈륨 나이트라이드의 혼합 결정을 전이층에 공급함으로써 격자 결함이 발생하지 않도록 한다.
Doverspike 등의 Mat. Res. Soc. Symp. Proc. Vol. 482, page 1169(1998))에는, 단결정 6H-SiC 기판에 금속-유기 화학 기상 증착법에 의하여 성장된 AIN-InN-GaN 시스템 조성을 가지는 단결정 박막이 개시되어 있다. 이로부터 청색 LED와 레이저 다이오드 구조가 제조된다. 도전 버퍼층 LED는 실리콘 카바이드와 활성 소자 영역 사이의 도전 경로를 제공하는 AlGaN 버퍼층을 사용하였다. 보라색과 청색 레이저 다이오드가 제조되고 분리 한정된 헤테로구조 설계에 따라 8개의 우물이 있는 InGaN-GaN 다중 양자 우물 활성 영역으로 이루어진다. 레이징(lasing)은 절연 버퍼 층을 사용하는 구조와 도전 버퍼 층을 사용하는 구조에서 모두 얻을 수 있었다.
