Thaum Lub Kaum Ib Hlis 22, cov npe ntawm cov neeg raug xaiv tshiab ntawm Tsev Kawm Txuj Ci Kev Kawm Txuj Ci hauv 2019 tau raug tshaj tawm. Tus kws tsim cov silicon substrate LED thev naus laus zis, tus tsim ntawm Jingneng Optoelectronics, thiab tus xibfwb Yang Changfeng ntawm Nanchang University, Nws Dag, uas yog lub siab tshaj plaws ntawm lub tebchaws rau nws qhov kev ua tiav scientific, thiab nws tseem yog 2015 lub teb chaws thev naus laus zis kev tsim kho tshiab tom qab. lub tshuab silicon substrate LED tshuab Vim tias thawj nqi zog, lwm qhov kev tshwm sim zoo hauv Tuam Tshoj LED teeb pom kev lag luam.
Thaum pib xyoo 1997, xibfwb Jiang Fengyi tau pib tshawb fawb ntawm LED thev naus laus zis, tab sis tsis txaus siab nrog kev taug ua simulation. Nyob rau xyoo 2003, xibfwb Jiang Fengyi tau coj pab pawg los pib tshawb fawb txog kev loj hlob ntawm gallium nitride LED cov ntaub ntawv ntawm cov roj silicon substrates. Xyoo 2005, lub tuam txhab thev naus laus zis loj tau tiav. Nyob rau xyoo 2006, nws thiab Wang Min thiab lwm tus tau qhia txog kev sib koom ua lag luam los sib koom ua ke Jingneng Optoelectronics, uas yog thawj zaug hauv lub ntiaj teb kom paub txog kev lag luam loj ntawm silicon substrate xiav LEDs. Thawj qhov khoom plig ntawm 2015 National Technological Invention Award tau siv rau silicon substrate LED thev naus laus zis, uas tau tsim Tuam Tshoj txoj haujlwm ua tus thawj coj hauv lub ntiaj teb silicon substrate LED thev naus laus zis.
Tom qab 13 xyoos ntawm kev txhim kho tshiab ntawm silicon substrate xiav lub teeb ci LED technology, cov khoom lag luam ua tiav khiav mus nrog cov chaw tsim khoom thoob ntiaj teb. Jingneng Optoelectronics 'silicon substrate xiav lub teeb ci LED nti muaj txoj cai ywj pheej ntawm cov tswv cuab, uas tuaj yeem tsav nrog lub zog loj thiab siab tam sim no. Zoo zoo, tshav kub dissipation thiab kev ntseeg siab. Nws muaj ntau cov kev siv hauv kev siv hluav taws xob muaj teeb pom kev zoo xws li tsheb teeb pom kev zoo, lub xov tooj ntawm lub xov tooj, thiab lub teeb pom kev zoo ntawm lub xov tooj txawb. Nws tau ua tiav tiav kev hloov chaw, thiab nws cov kev xa khoom yog ib qho siab tshaj plaws hauv kev lag luam. Nyob rau tib lub sijhawm, silicon-based LED xiav lub teeb thev naus laus zis tau tsim lub tshuab roj silicon-based LED kev lag luam nrog Jingneng Optoelectronics-Crystal Energy Semiconductors-CEC Crystal thiab Teeb-Greenfield Automotive Teeb ua lub tuam txhab loj, thiab tau tsim Nanchang Teeb hauv lub Jiangxi Xeev Tsoom Fwv. Nrog txoj cai faib nyiaj tsim ntawm 100 billion peev puag, nws tau nyiam ntau thiab ntau lub tuam txhab LED, xws li Tuam Tshoj Micro Semiconductor, Hongli Optoelectronics, Zhaochi Optoelectronics, Qianzhao Optoelectronics, thiab Emacs.com. Tsim cov kev lag luam ua tiav LED pawg nrog kev ua tiav kev paub ywj pheej.
Silicon substrate LED thev naus laus zis yog deb tshaj li lub teeb xiav LED. Raws li silicon substrate LED xiav lub teeb ci thev naus laus zis, nws tuaj yeem txuas rau ultraviolet, daj-ntsuab lub teeb, cov khoom siv hluav taws xob thiab lwm cov teb. Jingneng Optoelectronics tau ua tiav kev tsim cov khoom siv roj silicon substrate UV LED lub teeb ci, uas yog siv dav hauv kev lag luam kev kho mob (number case, luam ntawv, thiab lwm yam), ntsia thawv kos duab, yoov tshaj cum thiab lwm cov teb, thiab kuj yog qib ntawm cov kev lag luam sab hauv. Hauv thaj teb ntawm kev siv thev naus laus zis, Jingneng Optoelectronics tau txuas ntxiv qhov zoo ntawm cov loj-silicon substrate LED thev naus laus zis mus rau Micro LED thiab gallium nitride cov khoom siv hluav taws xob, tshwj xeeb tshaj yog gallium nitride cov khoom siv hluav taws xob, ua lub teb chaws hauv cov khoom lag luam epitaxy. Nyob rau tib lub sijhawm, xibfwb Jiang Fengyi pawg neeg lub silicon substrate LED daj-ntsuab thev naus laus zis yog nyob rau theem kev coj ua ntej hauv lub ntiaj teb, thiab cov haujlwm ua haujlwm tau raug lees paub los ntawm cov tub ceev xwm thoob ntiaj teb suav nrog Nobel nqi zog Physics Shuji Nakamura.
Nws yog conceivable tias silicon substrate LED thev naus laus zis yog lub hauv paus thev naus laus zis uas tuaj yeem npog cov ceg ntoo sib txawv xws li ultraviolet, lub teeb xiav, lub teeb ntsuab, thiab cov khoom siv hluav taws xob. Txhua lub tuam txhab thev naus laus zis muaj peev xwm yug tau ntau txoj saw lag luam, yam tsis muaj ceg ntoo thiab nplooj ntoo, thiab hlob zoo. loj hlob. Jingneng Optoelectronics Thawj Tswj Hwm Wang Min ntseeg ntau txog qhov no. Nws hais tias: xibfwb Jiang Fengyi kev xaiv tsa ua tus kws tshaj lij yog lwm qhov kev txhawb rau silicon substrate LED thev naus laus zis. Hauv tsib xyoos tom ntej, los ntawm kev siv thev naus laus zis, kev txhawb nqa nyiaj, lub tsev zes Ua raws kev siv tshuab thev naus laus zis, silicon substrate LED kev lag luam yuav nyiam thiab tsim kev lag luam ntau pua, ua rau 30 billion yuan high-end tshwj xeeb teeb pom kev lag luam pawg hauv Nanchang.
