I-Metal-organic chemical vapor deposition (MOCVD) iyindlela evame ukusetshenziswa ye-semiconductor epitaxy esetshenziselwa ukufaka amafilimu anelaya eningi endaweni yamawafa e-semiconductor ukuze kulungiswe izinto zekhwalithi ephezulu ze-semiconductor. Izingxenye ze-MOCVD epitaxial zidlala indima ebalulekile embonini ye-semiconductor futhi zisetshenziswa kakhulu kumadivayisi we-optoelectronic, ezokuxhumana optical, amandla e-photovoltaic kanye nama-lasemiconductor lasers.
Enye yezinhlelo zokusebenza eziyinhloko zezingxenye ze-MOCVD epitaxial ukulungiswa kwamadivaysi e-optoelectronic. Ngokufaka amafilimu anezingqimba eziningi zezinto ezihlukene kumawafa we-semiconductor, amadivayisi afana nama-optical diode (LED), ama-laser diode (LD) nama-photodetectors angalungiswa. Izingxenye ze-MOCVD ze-epitaxial zinokufana okuhle kakhulu kwezinto kanye nekhono lokulawula ikhwalithi yesixhumi esibonakalayo, ezingakwazi ukubona ukuguqulwa kwe-photoelectric okuphumelelayo, ukuthuthukisa ukusebenza kahle okukhanyayo nokuzinza kokusebenza kwedivayisi.
Ngaphezu kwalokho, izingxenye ze-MOCVD epitaxial nazo zisetshenziswa kabanzi emkhakheni wokuxhumana optical. Ngokufaka izendlalelo ze-epitaxial zezinto ezihlukahlukene, ama-amplifiers optical semiconductor optical anesivinini esiphezulu futhi asebenzayo kanye nama-modulators optical angalungiswa. Ukusetshenziswa kwezingxenye ze-MOCVD epitaxial emkhakheni wokuxhumana optical kungasiza futhi ukuthuthukisa izinga lokudlulisela kanye namandla okuxhumana kwe-fiber optical ukuhlangabezana nesidingo esikhulayo sokudluliswa kwedatha.
Ngaphezu kwalokho, izingxenye ze-MOCVD epitaxial nazo zisetshenziswa emkhakheni wokukhiqiza amandla we-photovoltaic. Ngokufaka amafilimu ama-multilayer anezakhiwo zebhendi ezithile, amaseli elanga asebenza kahle angalungiswa. Izingxenye ze-MOCVD ze-epitaxial zingahlinzeka ngezingqimba ze-epitaxial zekhwalithi ephezulu, ezihambisana ne-lattice, ezisiza ukuthuthukisa ukusebenza kahle kokuguqulwa kwe-photoelectric kanye nokuzinza kwesikhathi eside kwamaseli elanga.
Okokugcina, izingxenye ze-MOCVD epitaxial nazo zidlala indima ebalulekile ekulungiseleleni ama-lasemiconductor lasers. Ngokulawula ukwakheka kwezinto kanye nokujiya kwesendlalelo se-epitaxial, ama-laser we-semiconductor ama-wavelengths ahlukene angenziwa. Izingxenye ze-MOCVD epitaxial zinikeza izendlalelo ze-epitaxial zekhwalithi ephezulu ukuze kuqinisekiswe ukusebenza okuhle kokubona kanye nokulahlekelwa okuphansi kwangaphakathi.
Ngamafuphi, izingxenye ze-MOCVD epitaxial zinezinhlobonhlobo zezinhlelo zokusebenza embonini ye-semiconductor. Bayakwazi ukulungiselela amafilimu ekhwalithi ephezulu ye-multilayer ahlinzeka ngezinto ezibalulekile zamadivayisi we-optoelectronic, ukuxhumana optical, i-photovoltaic power generation kanye nama-lasemiconductor lasers. Ngokuthuthuka okuqhubekayo kanye nokuthuthukiswa kobuchwepheshe be-MOCVD, inqubo yokulungiselela izingxenye ze-epitaxial izoqhubeka nokuthuthukiswa, iletha emisha emisha kanye nempumelelo ekusetshenzisweni kwe-semiconductor.
