Is-waafajinta indhaha: Chip Violet Sare si uu ugu tartamo Globes Dahabka ah 2015 Injineernimada

[qoraal / Injineer LED Yue Motte] wax soo saarka iftiinka garoon LED iyo cilmi-baarista injineernimada Institute (GGII) xogta sahanka ayaa muujinaya in 2015 wax soo saarka chip epitaxial LED gaari doonaa 14.8 bilyan yuan, koritaanka hoos u dhac, laakiin waqti isku mid ah Data ayaa sidoo kale muujinaysaa in tan iyo markii qeybtii hore ee 2012 ilaa 2015, celceliska margin guud kor u yara kor u kacay, qiimaha wax soo saarka hoos u dhacay, taasoo muujinaysa in warshaduhu waxay galeen tartan wanaagsan. Habka aasaasiga ah ee awoodda sare ee LED chip iftiinka daadka ayaa la dejiyay, soosaarayaasha chips kala duwan ayaa asal ahaan laga helay hab nololeed ku habboon. Waxaa ka mid ah, saddexda guddi ee cusub waxay liis gareeyeen shirkadaha New Harmony photoelectric (832,502), oo sidoo kale loo yaqaano sifooyinkeeda wanaagsan ee joogtada ah ee suuqa. is-waafajinta backpfrontp Optoelectronics waxaa la aasaasay dabayaaqadii 2010, waxa ay la kulantay in ka badan afar sano oo horumarineed waxa ay noqotay lagama maarmaan ah oo muhiim ah 1000W LED warshadaha iftiinka daadka kor u alaab-qeybiyeyaasha, iyadoo wax soo saarka sanadlaha ah ee 400 million yuan, alaabta waxaa loo dhoofiyaa dibadda. Shirkadda 2014 waxay bilowday inay horumariso awoodda sare ee violet chip iyo guusha bilowga ah, iyada oo loo marayo anshaxa suuqa iyo jawaab celinta macaamiisha joogtada ah, waxayna samaysay horumar wanaagsan. Sida laga soo xigtay Xu Qi backpbackpfrontp wada noolaanshaha photovoltaic maareeyaha mashruuca, shirkadda ee awoodda sare ee violet PSS sapphire substrate ku salaysan chip ilaa koraya lakabka epitaxial ah, iyadoo la isticmaalayo nalalka cusub ee jimicsiga nooca PSS substrates, habka laba-tallaabo si loo xaliyo dhibaatada koritaanka liidata taasoo keentay crystal tayada Dhanka kale, qaabka korriinka saddex-geesoodka ah ee xawaaraha hooseeya, si loo hagaajiyo tayada crystal ee lakabka epitaxial, waxaa suurtagal ah in la yareeyo cufnaanta cilladda, hagaajinta waxtarka gudaha gudaha. backpfrontp Dhanka kale, chip wuxuu isticmaalaa zigzag quantum si fiican design, hagaajinta ceelasha quantum ee sidayaal si loo hagaajiyo ixtimaalka dib-u-habeynta elektarooniga ah, Xu Qi oo sii hadlay ayaa sheegay in jajabka lakabka N-nooca iyo lakabyada P-nooca ay sameeyeen noocyo kala duwan. hagaajinta, samaynta lakabka N-nooca iyo lakabka nooca P si loo yareeyo nuugista violet, waxay hagaajin kartaa waxtarka iftiinka violet. Si aad u hesho tayo sare leh oo qoto dheer UV LED bay iftiinka is-waafajinta sawir-qaade sidoo kale isku day inaad qaadato farsamooyin korriin dusha sare ah oo aan dabaylaha ahayn ama semi-polar diyaarad ah oo ku jira substrate GaN isku midka ah, qayb ahaan meesha ka saar saamaynta quantum Stark ee ay keentay beerta korantada. backpfrontp ka falcelinta suuqa, wada noolaanshaha ee macaamiisheeda photovoltaic aad ugu qanacsan yihiin alaabta-xoog sare leh guduudan, in si buuxda u fahmi kara baahida macaamiisha, iyo taagan barta ganacsiga aragtida, si ay u bixiyaan adeegyo badan oo la-talin farsamo. backpfrontp waxaan rajeyneynaa in alaabtayada ma aha oo kaliya la kulmi karaan imtixaanka suuqa sidoo kale waa ay awoodaan in ay ku guulaystaan ​​ammaanta asxaabta iyo khubarada, ku guulaysato a Golden Globe sanadkan ee Engineering LED nalalka wadada. Harmony photoelectric Xiangdong ayaa muujiyay.
