I-Metal-organic chemical vapor deposition (MOCVD) bubuchule obusetyenziswa ngokuqhelekileyo be-semiconductor epitaxy esetyenziselwa ukufaka iifilimu ezininzi ngaphaya kwee-wafers ze-semiconductor ukulungiselela imathiriyeli yomgangatho ophezulu we-semiconductor. Amacandelo e-MOCVD epitaxial adlala indima ebalulekileyo kwishishini le-semiconductor kwaye asetyenziswa ngokubanzi kwizixhobo ze-optoelectronic, unxibelelwano lwe-optical, ukuveliswa kwamandla e-photovoltaic kunye ne-lasemiconductor lasers.
Esinye sezicelo eziphambili ze-MOCVD epitaxial components kukulungiswa kwezixhobo ze-optoelectronic. Ngokufaka iifilimu ezininzi zezixhobo ezahlukeneyo kwi-semiconductor wafers, izixhobo ezifana ne-optical diodes (LED), i-laser diodes (LD) kunye ne-photodetectors zinokulungiswa. Izixhobo ze-MOCVD ze-epitaxial zinezinto ezibonakalayo ezintle kakhulu kunye nezakhono zokulawula umgangatho wojongano, ezinokuqonda ukuguqulwa kwe-photoelectric ngokufanelekileyo, ukuphucula ukusebenza kakuhle okukhanyayo kunye nokuzinza kokusebenza kwesixhobo.
Ukongeza, iinxalenye ze-MOCVD epitaxial nazo zisetyenziswa ngokubanzi kwinkalo yonxibelelwano lwe-optical. Ngokubeka iileyile ze-epitaxial zezinto ezahlukeneyo, i-high-speed and efficient semiconductor optical amplifiers kunye ne-optical modulators zinokulungiswa. Ukusetyenziswa kwamacandelo e-MOCVD epitaxial kwintsimi yokunxibelelana kwe-optical kunokunceda ukuphucula izinga lokudluliselwa kunye nomthamo wonxibelelwano lwe-fiber optical ukuhlangabezana nemfuno ekhulayo yokuhanjiswa kwedatha.
Ukongezelela, iinqununu ze-MOCVD epitaxial nazo zisetyenziswa kwintsimi yokuvelisa amandla e-photovoltaic. Ngokubeka iifilimu ezininzi ezinezakhiwo zebhendi ezithile, iiseli ezisebenzayo zelanga zinokulungiswa. Amacandelo e-MOCVD epitaxial anokubonelela ngekhwalithi ephezulu, i-lattice ephezulu ehambelana ne-epitaxial layers, enceda ukuphucula ukuguqulwa kwe-photoelectric ukusebenza kakuhle kunye nokuzinza kwexesha elide leeseli zelanga.
Ekugqibeleni, amacandelo e-MOCVD epitaxial nawo adlala indima ebalulekileyo ekulungiseleleni i-lasemiconductor lasers. Ngokulawula ukubunjwa kwezinto kunye nobukhulu be-epitaxial layer, i-lasemiconductor lasers ye-wavelengths eyahlukeneyo inokwenziwa. Izixhobo ze-MOCVD ze-epitaxial zibonelela ngomgangatho ophezulu we-epitaxial layers ukuqinisekisa ukusebenza kakuhle kwe-optical kunye nelahleko ephantsi yangaphakathi.
Ngamafutshane, amacandelo e-MOCVD epitaxial anoluhlu olubanzi lwezicelo kwishishini le-semiconductor. Bayakwazi ukulungiselela iifilimu eziphezulu ze-multilayer ezibonelela ngezinto eziphambili zezixhobo ze-optoelectronic, unxibelelwano lwe-optical, ukuveliswa kwamandla e-photovoltaic kunye ne-lasemiconductor lasers. Ngophuhliso oluqhubekayo kunye nokuphuculwa kweteknoloji ye-MOCVD, inkqubo yokulungiselela iingxenye ze-epitaxial iya kuqhubeka iphuculwa, izisa izinto ezintsha kunye nokuphumelela kwizicelo ze-semiconductor.
