I-Substrate ye-Sapphire Enephethini engu-2 intshi engu-4 intshi engu-6 intshi (i-PSS) lapho kutshalwa khona izinto ze-GaN ezingasetshenziswa ekukhanyiseni kwe-LED
Izici eziyinhloko
1. Izici zesakhiwo:
Ubuso be-PSS bunekhoni ehlelekile noma iphethini eliyindilinga elingunxantathu lapho ukuma, usayizi kanye nokusatshalaliswa kungalawulwa ngokulungisa amapharamitha enqubo yokuqopha.
Lezi zakhiwo zezithombe zisiza ekushintsheni indlela yokusabalala kokukhanya futhi zinciphise ukubonakaliswa okuphelele kokukhanya, ngaleyo ndlela zithuthukise ukusebenza kahle kokukhishwa kokukhanya.
2. Izici zezinto:
I-PSS isebenzisa i-sapphire esezingeni eliphezulu njengezinto ezisetshenziswayo, ezinezici zobulukhuni obuphezulu, ukuqhuba okuphezulu kokushisa, ukuzinza okuhle kwamakhemikhali kanye nokubonakala okubonakalayo.
Lezi zici zivumela i-PSS ukuthi imelane nezimo ezinzima njengokushisa okuphezulu kanye nokucindezela ngenkathi igcina ukusebenza okuhle kakhulu kokukhanya.
3. Ukusebenza kwe-Optical:
Ngokushintsha ukuhlakazeka okuningi endaweni ehlangana ne-GaN kanye ne-sapphire substrate, i-PSS yenza ama-photon abonakala ngokuphelele ngaphakathi kwengqimba ye-GaN abe nethuba lokuphuma kwi-sapphire substrate.
Lesi sici sithuthukisa kakhulu ukusebenza kahle kokukhipha ukukhanya kwe-LED futhi sithuthukisa amandla okukhanya kwe-LED.
4. Izici zenqubo:
Inqubo yokukhiqiza ye-PSS iyinkimbinkimbi kakhulu, ihilela izinyathelo eziningi ezifana ne-lithography kanye ne-etching, futhi idinga imishini enembile kakhulu kanye nokulawulwa kwenqubo.
Kodwa-ke, ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nokunciphisa izindleko, inqubo yokukhiqiza ye-PSS ithuthukiswa kancane kancane futhi ithuthukiswa.
Inzuzo eyinhloko
1. Thuthukisa ukusebenza kahle kokukhipha ukukhanya: I-PSS ithuthukisa kakhulu ukusebenza kahle kokukhipha ukukhanya kwe-LED ngokushintsha indlela yokusabalalisa ukukhanya nokunciphisa ukubonakaliswa okuphelele.
2. Ukwandisa isikhathi sokuphila kwe-LED: I-PSS inganciphisa ubuningi bokuhlukaniswa kwezinto ze-epitaxial ze-GaN, ngaleyo ndlela inciphise ukuhlanganiswa okungasebenzisi imisebe kanye nomsinga wokuvuza obuyela emuva esifundeni esisebenzayo, yandisa isikhathi sokuphila kwe-LED.
3. Thuthukisa ukukhanya kwe-LED: Ngenxa yokuthuthukiswa kokusebenza kahle kokukhipha ukukhanya kanye nokwandiswa kokuphila kwe-LED, ukuqina kokukhanya kwe-LED ku-PSS kukhuliswa kakhulu.
4. Nciphisa izindleko zokukhiqiza: Nakuba inqubo yokukhiqiza ye-PSS iyinkimbinkimbi kakhulu, ingathuthukisa kakhulu ukusebenza kahle okukhanyayo kanye nokuphila kwe-LED, ngaleyo ndlela inciphise izindleko zokukhiqiza ngezinga elithile futhi ithuthukise ukuncintisana komkhiqizo.
Izindawo eziyinhloko zokusetshenziswa
1. Ukukhanya kwe-LED: I-PSS njengezinto ezisetshenziswayo zama-chip e-LED, ingathuthukisa kakhulu ukusebenza kahle okukhanyayo kanye nokuphila kwe-LED.
Emkhakheni wokukhanyisa nge-LED, i-PSS isetshenziswa kabanzi emikhiqizweni ehlukahlukene yokukhanyisa, njengezibani zasemgwaqweni, izibani zetafula, izibani zezimoto njalo njalo.
2. Amadivayisi e-semiconductor: Ngaphezu kokukhanyisa kwe-LED, i-PSS ingasetshenziswa futhi ukukhiqiza amanye amadivayisi e-semiconductor, njengezitholi zokukhanya, ama-laser, njll. Lawa madivayisi anezinhlelo zokusebenza eziningi kwezokuxhumana, kwezokwelapha, kwezempi nakweminye imikhakha.
3. Ukuhlanganiswa kwe-Optoelectronic: Izakhiwo zokukhanya kanye nokuqina kwe-PSS kuyenza ibe ngenye yezinto ezifanelekile emkhakheni wokuhlanganiswa kwe-optoelectronic. Ekuhlanganisweni kwe-optoelectronic, i-PSS ingasetshenziswa ukwenza ama-waveguides optical, ama-optical switch kanye nezinye izingxenye ukuze kufezwe ukudluliswa kanye nokucutshungulwa kwezimpawu zokukhanya.
