Semiconductor daj LED thev naus laus zis tau ua tiav qhov kev vam meej
Tom qab 57 xyoo ntawm txoj kev txhim kho, pom lub teeb pom kev zoo LED tau ua tiav xim, muab tib neeg nrog kev ua yeeb yam pom kev zoo thiab ua kom lub zog txuag hluav taws xob muaj txiaj ntsig zoo. Txawm li cas los xij, rau lub sijhawm ntev, kev txhim kho cov yeeb yuj LED teeb pom kev zoo (lub zog ua kom muaj zog) yog qhov tsis sib xws. Ntawm lawv, lub teeb pom kev zoo ntawm cov xim daj LED yog qis dua li ntawm lwm cov xim. Raws li qhov tshwm sim, lub teeb daj nrog lub teeb pom kev zoo yuav tsum tau txais los ntawm kev hloov pauv nthwv dej ntawm phosphors. Qhov no" hluav taws xob-kho qhov muag-kho qhov muag" kev hloov pauv thev naus laus zis tam sim no yog thev naus laus zis tseem ceeb ntawm LED teeb pom kev zoo. Txawm li cas los xij, phosphors muaj qhov tsis xws luag hauv txoj kev hloov pauv mus rau lub teeb, xws li cov cua sov poob loj, cua sov loj thiab lub teeb tawg, thiab teb qeeb, uas txwv qhov kev txhim kho sai ntawm LEDs hauv kev coj ua kom pom kev zoo thiab siab ceev pom lub teeb sib txuas lus.
Yog li ntawd, daws qhov" qhov sib txawv ntawm lub teeb daj" tau dhau los ua lub hom phiaj txaus nyiam hauv daim teb no. Cov substrate zoo li cas, cov khoom siv, cov qauv siv, cov qauv nti, thiab cov cuab yeej tuaj yeem siv los tsim cov khoom lag luam siab daj daj? Tsis muaj lus teb nyob hauv tsev thiab txawv teb chaws ntev.
Hauv ob lub teeb khoom siv lub teeb daj, raws li lub nthwv dej ntawm AlGaInP hloov pauv los ntawm lub teeb liab mus rau lub teeb daj, qhov sib txawv ntawm qhov hloov pauv ntawm ncaj qha mus rau qhov tsis ncaj, thiab qhov ua tau zoo poob qis. Qhov no yog lub cev tsis zoo; thaum indium gallium nitride yog cov kab sib txuas ncaj qha, uas yog qhov loj tshaj Qhov Nyuaj nyuaj yog kom loj hlob zoo, cov ntsiab lus indium siab indium gallium nitrogen quantum cov khoom zoo, uas yog qhov tsis zoo. Kev sib xyaw indium ntawm cov xim daj daj daj LED yog kwv yees li 30%, uas pom tseeb tshaj li qhov sib xyaw ntawm indium ntawm xiav quantum zoo txog 15%. Muaj ntau qhov nyuaj hauv kev loj hlob ntawm indium gallium nitrogen nrog cov ntsiab lus siab indium: qhov kub tsis loj hlob ua rau ammonia tawg, tsis muaj nitrogen ntau dua, tsis muaj kev txav chaw atom qeeb thiab ntxhib nto, tsis pom kev thiab teeb meem cuam tshuam nrog cov tuab sib txawv, tsis sib xws indium muaj pes tsawg leeg, thiab sib cais indium hnyav Sib cais theem, InGaN/GaN muaj zog polarization nqa tsawg dua kev sib tshooj ntawm cov khoom siv yoj ua haujlwm, thiab ntxiv rau.
Tsis ntev los no, Jiang Fengyi tshawb fawb pab pawg ntawm Nanchang University tau tshaj tawm ib tsab xov xwm hauv Kev Tshawb Fawb Photonics: Ua Tau Zoo InGaN raws li Lub Teeb Daws Teeb Pom Kev Daj, uas qhia pom qhov kev vam meej hauv kev tsim thiab tsim khoom siv thev naus laus zis ntawm cov teeb liab daj. Raws li tus thawj GaN/Si-based cov khoom siv xiav xiav LED, cov qauv khoom siv, thiab cov qauv nti, lawv tsim cov khoom siv tshiab, cov cuab yeej tsim kho tshiab thiab txheej txheem tshiab. Lawv hloov pauv peb qhov tsis sib xws loj (cov cua sov nthuav dav coefficient tsis sib xws, cov pawg loj sib txawv qhov dav tsis sib xws, thiab lub lattice loj loj tsis sib xws) rau hauv peb qhov zoo.
Cov pab pawg tshawb fawb tau tsim cov txheej txheem kev tsim cov khoom thiab thev naus laus zis. Ib daim phiaj tsis tu ncua tau tsim los ntawm cov khoom siv los hloov cov kab nrib pleb tsis sib xws, uas tshem tawm GaN/Si kev nyuab siab txuam nrog thiab daws qhov teeb meem ntawm cov kab nrib pleb los ntawm cov khoom siv. Qhov teeb meem tsis muaj peev xwm tsim cov teeb pom kev zoo kuj muaj qhov zoo ntawm kev loj hlob ua tau zoo indium gallium nitride cov ntaub ntawv nrog cov ntsiab lus siab indium vim tswj GaN nyob rau hauv lub zog tensile.
Cov kws tshawb fawb tau tsim cov txheej txheem silicon-based LED nti nrog lub teeb pom kev zoo los ntawm kev hloov kho tam sim no, txoj haujlwm teeb pom kev, thiab txoj kev teeb pom kev, uas tsis tsuas yog daws qhov teeb meem ntawm lub teeb nqus dej nqus thiab hluav taws xob thaiv lub teeb, tab sis kuj muaj qhov zoo ntawm ib leeg ib leeg lub teeb tso tawm thiab lub teeb siab zoo. Kev tsim kho txheej txheem txheej txheem hloov pauv tshiab tsis yog tsuas yog daws qhov teeb meem ntawm kev txav mus los siab, tab sis kuj tseem siv qhov tsis sib xws los tsim cov cuab yeej siv nrog V qhov loj, txhim kho txoj hauv kev thauj mus los thiab txhim kho LED kev ua haujlwm.
Los ntawm kev hloov pauv peb qhov tsis sib xws loj rau hauv peb qhov txiaj ntsig zoo, lawv tau kho cov tshuaj tiv thaiv cov pa thauj mus los thiab cov txheej txheem tso tawm, tau tsim cov txheej tuab tuab coaxial lub tes tsho cov tshuaj tiv thaiv chav, thiab tsim cov khoom sib xyaw siab uas muaj txiaj ntsig zoo rau kev koom nrog ntawm indium. Cov khoom siv indium gallium nitride cov khoom siv txhim kho qhov kub thiab txias ntawm cov khoom, txo qhov kev nco, thiab ua rau quantum zoo thiab teeb meem cuam tshuam; tsav los ntawm qhov ceev tam sim no ntawm 20A/cm2 thiab 3 A/cm2, 565nm silicon-based daj LED lub teeb Kev ua haujlwm tau nce ntxiv mus rau 24.3% thiab 33.7%, sib xws rau 149 lm/W thiab 192 lm/W, feem, yog li ua tau zoo daws qhov teeb meem daj thiab daws qhov teeb meem ntawm qhov tsis muaj qhov ua tau zoo ntawm lub teeb daj hauv LEDs hauv ntiaj teb.
Cov khoom siv yog silicon substrate indium gallium nitride ntau qhov qauv zoo uas muaj peb sab PN sib tshuam nrog V qhov loj, thiab nti yog ib leeg ib sab teeb pom kev, nyias zaj duab xis.
