Lisebelisoa tsa mabone a mabone a LED li kopantsoe le katoloso, substrate, sephutheloana, lifaha tsa lebone la lebone le lesoeu, joalo-joalo. Lifaha tsa lebone tsa LED tse khubelu, tse tala le tse putsoa ke metsoako ea lebelo la III-V joalo ka phosphorus, arsenic, nitrogen, joalo-joalo. GAN) le litsamaiso tse ling tsa tataiso. 1. Bokhoni ba theko ea lifaha tsa mabone a LED bo atolositsoeng ka lilemo tse fetang leshome bo ntlafalitse ts'ebetso ea kholo ka mokhoa oa ntlafatso. Leha ho le joalo, naetrojene galfa gan ea lifaha tsa mabone a tloaelehileng a masoeu a mabone le lesela la lesela le pakeng tsa substrate le coefficient e sa khotsofatseng ea coefficient ea katoloso ea mocheso e ntse e baka sets'oants'o se phahameng haholo sa -bit error density. Ka nako e telele, e 'nile ea e-ba ho ithuta bokhoni ba lifaha tsa lebone la LED ho fokotsa ho teteana ha lebone le ho ntlafatsa boleng ba kristale ea lifaha tsa lebone la LED ho fihlela bosiu bo bongata. Katoloso ea lifaha tsa mabone a LED ke lefapha le tsepamisisang maikutlo la lifaha tsa mabone a LED. Bophahamo ba maqhubu, matla a pele, khanya, kapa khanya e khanyang ea lifaha tsa lebone la LED ha e le hantle li ipapisitse le thepa. Bokhoni ba katoloso le lisebelisoa ke senotlolo sa litsebo tsa tlhahiso ea filimi ea katoloso. Metal organic material qi deposition skills (MOCVD) ke karolo ea bohlokoa ea kholo ea lifaha tsa lebone la III-LED. Ho ba sieo ha lesela la ka ntle ho sebelisoa e le setsi se sa khanyeng se se nang mahlaseli, se nang le tšusumetso e kholo haholo mosebetsing oa optical oa sesebelisoa. Katoloso ea mabone a mabone a LED le lipatlisiso tsa mahlale a katoloso: Tsebo ea kholo ea lifaha tsa lebone la LED ke moimana, le palo e kholo ea subtitles le likarolo tse tlase tsa INgan tsa khatello ea maikutlo pele ho nako. “Storage pond ”Ebe o futhumatsa le ho holisa lera la thibelo ea GAN ho ntlafatsa boleng ba kristale ea lera la mokoallo, sekhahla sa thibelo ea Ingaaln kapa khatello ea kholo ea kholo ea grid. Sefi sa quantum se na le sebaka sa mohloli Ingan / Gan quantum trap. Sebaka sa mohloli ke sepheo sa mabone a lebone la LED. Senotlolo sa ho holisa Ingan quantum trap ke ho laola khatello ea maikutlo ea leraba la quantum, ho fokotsa litlamorao tsa litlamorao tsa polarization. Khōlo ea lifaha tsa lebone la LED lilemong tse fetileng, lera la katoloso ea mabone a lebone la LED le litsebo tsa ho atolosa li se li hōlile. Bokhoni ba ka hare ba mabone a mabone a LED bo fihlile ho feta 90%. Leha ho le joalo, boithutong ba lifaha tsa mabone a matla a LED, katleho ea palo ea ho qaptjoa ha ente ea hona joale ea selemo e bohlokoa, 'me e bitsoa phello ea DROOP. Phello ea DROOP ea lifaha tsa lebone tsa LED tse thehiloeng ho GAN qalong e ne e le leeme mabapi le ho fihla sebakeng sa mojari. Moqapi oa liteko o amohela leraba le pharaletseng la ho fokotsa sekhahla sa sepalangoang le ho ntlafatsa lera la elektroniki la ho kenella sebakeng se nang le sebopeho sa P. Tsebo e 'ngoe e qaqileng ea sebopeho sa katoloso ea libaha tsa lebone la LED le lipatlisiso tsa mahlale a katoloso ke: Ponahalo ea ponahalo e thata Lifaha tsa lebone tsa LED li lieha ho hlaha, tse lumellanang le sekhutlo sa phetoho ho thibela khanya e felletseng ea leseli. Phapang lipakeng tsa index ea refractive le thepa ea ho paka e bakoa ke ho tsoa ha sets'oants'o sa lefapha ho tla bonts'oa morao ho karolo e atolositsoeng. Mokhoa ona o fuoa kotlo ka ho toba bakeng sa ho lahla ponahalo ea katoloso, 'me ho bonolo ho senya katoloso ea mohloli oa katoloso,' me electrode e bonaletsang e thata ho e haha. Ke tsela e ka khonehang ea ho fihlela ponahalo e thata ka phetoho ea katoloso ea lera la ho lieha ha kantle. Bokhoni ba ho sebetsa Lifaha tsa lebone tsa LED tsa sapphire substrate laser stripping li thehiloe holima GAN homogeneous extension and growth skills, coaxing UV laser irradiation base, melting transition layer peeling. Ho isa ho 75%, e menahane ka makhetlo a mararo, 'me e thehile moeli oa tlhahiso. Lebone la lebone la LED le tšela tsebo ea chip. Ho latela lintlha tsa khamphani ea Lumileds, likhahla tsa lebone tsa LED tsa sapphire substrate sekhahla sa kholo ea makhetlo a ka bang 1.6. Ntle le leseli le ka pele la lifaha tsa lebone la LED, ntle le ka pele ho lebone, leseli la lifahleho tsa lifahleho tse ling le bonahatsa ka hohle kamoo ho ka khonehang ho khutlela katoloso ea katoloso, 'me papatso ea ho qetela e tsoa ka pele ho ka pele. Sebopeho se senyenyane sa likristale tsa photon tse peli-dimensional tsa lifaha tsa lebone tsa Lyric li ka feta bokhoni ba khanya e tlōlang. Ka September 2003, ho ile ha hahoa lifaha tsa lebone la LED tse bophara ba 1.5 microns le 0.5 microns ka bolelele ba 0.5 microns. Ea bobeli, setsi sa chip sa lifaha tsa lebone la LED hangata se sebelisa lisebelisoa tsa chip base hangata li sebelisa li-sapphire substrates, silicon carbide substrate, silicon substrate bosiu ba lilemo tse tharo, hammoho le nitride, zinc oxide joalo-joalo. Finyella litlhoko tsa thepa ea substrate: Ho se feto-fetohe ha lik'hemik'hale tsa karoloana ea sefaha sa lumine le lera la ka ntle la lera li tsamaisana. Lisebelisoa tsa substrate li tlameha ho ba le ho se feto-fetohe ha lik'hemik'hale tse ntle. Pontšo ea lik'hemik'hale ea ho tsoala ha lera e etsa hore boleng ba lera le otlolohileng le koale; Lebone la lebone la lebone la LED le tsamaisana le coefficient ea katoloso ea mocheso ea lera le otlolohileng la membrane, 'me li-coefficients tsa katoloso ea mocheso li fapane. Ho senyeha ha sesebelisoa ho senyehile; sebopeho sa motheo oa lebone la LED le lera la ka ntle la lesela le tsamaisana. naha ea heso LED lebone lifaha silicon base litsebo tsa silicon e se e utloile bohloko ka lebaka la katleho ea litsebo, 'me ba ntse ba hola ho fihlela tshebediso ya thepa ea ho ea qetellong ea selemo. Hajoale, ke li-sapphire le li-silicon feela tse 'nileng tsa sebelisoa bakeng sa libaha tsa mabone a LED tse rekisoang ka GAN. Lisebelisoa tse ling tsa substrate tse ka sebelisoang bakeng sa lifaha tsa lebone tsa LED tse thehiloeng ho GAN li arohanngoa le thepa 'me li lumellana le li-substrates tse homogeneous tsa GAN le li-substrates tsa ZNO.
