Cov lus qhia luv luv
Silicon hlau yog ib qho tseem ceeb semiconductor cov khoom siv nrog cov tshuaj lom neeg si. Nws mas muaj nyob rau hauv daim ntawv ntawm silicon dioxide (xws li quartz) thiab silicates hauv xwm. Kev Purity High Monocrystalline Silicon lossis Polycrystalline Silicon tuaj yeem tau txais los ntawm smelting thiab purification, uas yog cov tseem ceeb ntawm kev lag luam thiab photovoltaic.
Yam uas pab
Cov yam ntxwv ntawm cov: Bandgap Qhov dav dav ntawm silicon yog ib nrab (1.12 ev), ua rau nws tswj tau yooj yim los ntawm doping thiab haum rau tsim cov khoom siv hluav taws xob.
Cov ntsiab lus ntau: Cov ntsiab lus Silicon hauv lub ntiaj teb cov crust yog thib ob tsuas yog oxygen, nrog tus nqi oxygen, nrog tus nqi qis thiab yooj yim.
Siab ruaj ruaj: kev kub siab kuj, corrosion tsis kam, thiab ruaj khov nyob rau hauv cov chaw hnyav.
Muaj zog sib haum: paub tab cov txheej txheem ua teChologies (xws li CMOS) txhawb nqa 95% ntawm kev sib koom tes hauv ntiaj teb.
Daim Ntawv Thov Cheeb Tsam
Kev lag luam hluav taws xob: Kev tsim khoom clawors, ics), chips, thiab lwm yam, siv rau cov khoos phis tawj, thiab cov khoom siv txawb.
Cov khoom siv photovoltotic: monocrystalline silicon thiab polycrystalline silicon yog cov ntaub ntawv tseem ceeb rau hnub ci hlwb, suav rau ntau tshaj 90% ntawm lub ntiaj teb photovoltaic kev ua lag luam.
Cov khoom siv Optoelrronic: siv rau kev sib txuas lus fiber ntau, lasers, thiab sensors.
Tshuaj lom neeg thiab cov ntaub ntawv: synthesize cov ntaub ntawv polymer xws li cov roj roj roj zoo li silicone, lossis siv lawv ua cov roj sib ntxiv (xws li cov roj silicon).
Cov khoom siv dav dav ntawm cov hlau silicon tau nce qib kev txhim kho cov ntaub ntawv thev naus laus zis thiab lub zog huv, thiab yog lub npe hu ua lub pob zeb ntawm kev lag luam niaj hnub.
