Umutungo wumubiri | C axis ifite urumuri rwa kirisiti, naho izindi axe zifite urumuri rubi. Indege C iringaniye, nibyiza gukata. | R-indege ikomeye cyane kurenza A. | M indege ikandagiye, ntabwo byoroshye gukata, byoroshye gukata. | Ubukomezi bwa A-indege buri hejuru cyane ugereranije na C-indege, igaragarira mukurwanya kwambara, kwihanganira gushushanya no gukomera cyane; Kuruhande A-indege ni indege ya zigzag, byoroshye guca; | ||
Porogaramu | C-yerekanwe na safiro substrate ikoreshwa mugukuza amafirime yabitswe III-V na II-VI, nka nitride ya gallium, ishobora kubyara ibicuruzwa bya LED byubururu, diode ya laser, hamwe na progaramu ya infragre. | R-yerekanwe substrate gukura kwa silicon itandukanye yabitswe, ikoreshwa muri microelectronics ihuza imiyoboro. | Ikoreshwa cyane cyane mugukuza amafilime adafite polar / igice-polar GaN epitaxial kugirango tunoze imikorere yumucyo. | A-yerekanwe kuri substrate itanga uruhushya rumwe / ruciriritse, kandi urwego rwo hejuru rwokwirinda rukoreshwa muburyo bwa tekinoroji ya mikorobe. Ubushyuhe bwo hejuru burashobora kubyazwa umusaruro A-shingiro rirambuye. | ||
Ubushobozi bwo gutunganya | Pattern Sapphire Substrate (PSS): Muburyo bwo Gukura cyangwa Etching, nanoscale yihariye ya microstructure isanzwe yateguwe kandi ikorwa kumurongo wa safiro kugirango igenzure imiterere yumucyo wa LED, kandi igabanye inenge zitandukanye muri GaN ikura kuri substrate ya safiro. , kuzamura ubwiza bwa epitaxy, no kuzamura kwimbere kwimbere ya LED no kongera imikorere yo gukuramo urumuri. Byongeye kandi, prism ya safiro, indorerwamo, lens, umwobo, cone nibindi bice byubatswe birashobora gutegurwa ukurikije ibyo abakiriya bakeneye. | |||||
