| Impahla engokoqobo | I-axis C inokukhanya kwekristalu, kanti ezinye izingqimba zinokukhanya okungekuhle. I-Plane C iyisicaba, kungcono ukuthi inqunywe. | Indiza engu-R inzima kancane kune-A. | Indiza i-M inezinsika ezinezitebhisi, akulula ukuyisika, kulula ukuyisika. | Ubulukhuni be-A-plane buphakeme kakhulu kunobe-C-plane, obubonakala ngokumelana nokuguguleka, ukumelana nokuklwebheka kanye nobunzima obukhulu; I-Side A-plane iyi-plane egobile, okulula ukuyisika; | ||
| Izicelo | Ama-substrates e-sapphire aqondiswe ku-C asetshenziselwa ukukhulisa amafilimu afakwe ku-III-V kanye ne-II-VI, njenge-gallium nitride, engakhiqiza imikhiqizo ye-LED eluhlaza okwesibhakabhaka, ama-laser diode, kanye nezinhlelo zokusebenza zokuthola i-infrared. | Ukukhula kwe-substrate okuqondiswe ku-R kwama-extrasystal e-silicon ahlukene abekwe phansi, asetshenziswa kumasekethe ahlanganisiwe e-microelectronics. | Isetshenziswa kakhulu ukukhulisa amafilimu e-epitaxial e-GaN angewona ama-polar/semi-polar ukuze kuthuthukiswe ukusebenza kahle kokukhanya. | I-A-oriented to the substrate ikhiqiza i-permittivity/medium efanayo, futhi izinga eliphezulu lokuvikela liyasetshenziswa kubuchwepheshe be-hybrid microelectronics. Ama-superconductor okushisa okuphezulu angakhiqizwa ngamakristalu amade e-A-base. | ||
| Umthamo wokucubungula | I-Pattern Sapphire Substrate (PSS): Ngendlela yokukhula noma ukuqopha, amaphethini e-microstructure ajwayelekile e-nanoscale aklanywa futhi enziwa ku-substrate ye-sapphire ukulawula uhlobo lokukhipha ukukhanya kwe-LED, nokunciphisa amaphutha ahlukene phakathi kwe-GaN ekhula ku-substrate ye-sapphire, kuthuthukiswe ikhwalithi ye-epitaxy, futhi kuthuthukiswe ukusebenza kahle kwe-quantum ye-LED futhi kwandiswe ukusebenza kahle kokukhishwa kokukhanya. Ngaphezu kwalokho, i-sapphire prism, isibuko, ilensi, umgodi, ikhoni nezinye izingxenye zesakhiwo zingenziwa ngezifiso ngokuya ngezidingo zamakhasimende. | |||||
