Nkag siab txog Kev Siv Hluav Taws Xob
Hluav taws xob conductivity yog ib qho kev ntsuas ntawm cov khoom muaj peev xwm ua tau hluav taws xob tam sim no. Nws yog qhov sib txuam ntawm hluav taws xob tiv thaiv thiab feem ntau ntsuas hauv siemens ib meter (S / m). Rau PECVD (Plasma-Enhanced Chemical Vapor Deposition) graphite nkoj, hluav taws xob conductivity plays lub luag haujlwm tseem ceeb hauv cov txheej txheem deposition.
Graphite yog qhov zoo - paub hluav taws xob conductor. Nws muaj cov txheej txheem ntawm carbon atoms teem rau hauv hexagonal lattice. Lub delocalized electrons nyob rau hauv cov qauv graphite yog dawb txav, uas tso cai rau cov ndlwg ntawm hluav taws xob tam sim no. Thaum nws los txog rau PECVD graphite nkoj, lub peev xwm ua hluav taws xob sib npaug thiab ua tau zoo yog qhov tseem ceeb rau kev ua haujlwm ntawm PECVD txheej txheem.
Cov yam ntxwv cuam tshuam rau hluav taws xob conductivity ntawm PECVD Graphite Boats
Graphite Qib thiab Purity
Qib thiab purity ntawm graphite siv los tsim lub nkoj cuam tshuam nws cov hluav taws xob conductivity. High - purity graphite feem ntau muaj kev ua tau zoo dua vim tias impurities tuaj yeem ua qhov chaw tawg rau cov hluav taws xob, txo lawv txoj kev mus. Raws li tus neeg xa khoom, peb ua tib zoo xaiv cov khoom siv qib siab - graphite kom ntseeg tau tias qhov kev ua tau zoo ntawm hluav taws xob ntawm peb PECVD Graphite Boats.
Microstructure
Lub microstructure ntawm graphite, nrog rau cov℃ntawm graphitization thiab orientation ntawm graphite crystallites, cuam tshuam conductivity. Zoo - graphitized graphite nrog qib siab ntawm crystallite alignment muaj ntau dua conductivity. Thaum lub sijhawm tsim khoom, peb siv cov txuj ci siab heev los tswj cov microstructure ntawm graphite, txhim kho nws cov khoom hluav taws xob.
Kub
Qhov kub thiab txias muaj txiaj ntsig zoo rau cov hluav taws xob conductivity ntawm graphite. Feem ntau, cov hluav taws xob conductivity ntawm graphite txo qis nrog nce kub. Hauv cov txheej txheem PECVD, qhov kub thiab txias tuaj yeem sib txawv, thiab nkag siab txog qhov hloov pauv ntawm qhov kub thiab txias yog qhov tseem ceeb rau kev ua kom zoo dua.
Kev kho saum npoo
Kev kho deg siv rau lub nkoj graphite kuj tuaj yeem cuam tshuam nws cov hluav taws xob conductivity. Qee qhov kev kho mob yuav qhia txog cov txheej nyias nyias ntawm qhov chaw uas tuaj yeem txhim kho lossis txo cov conductivity, nyob ntawm qhov kev kho mob. Peb muab ntau yam kev kho mob saum npoo av rau peb cov nkoj graphite, coj mus rau hauv tus account cov kev cai tshwj xeeb ntawm peb cov neeg siv khoom.
Qhov tseem ceeb ntawm Kev Siv Hluav Taws Xob hauv Cov Txheej Txheem PECVD
Uniform Deposition
Hauv PECVD system, hluav taws xob tam sim no yog siv los tsim cov plasma, uas yog lub luag haujlwm rau tso cov yeeb yaj kiab nyias ntawm cov substrates. Lub nkoj PECVD graphite nrog cov khoom siv hluav taws xob zoo ua kom ntseeg tau tias cov plasma sib npaug sib npaug thoob plaws lub nkoj. Qhov no, nyob rau hauv lem, ua rau uniform deposition ntawm nyias films nyob rau hauv lub substrates muab tso rau hauv lub nkoj. Tsis yog - kev coj ua tsis sib xws tuaj yeem ua rau cov yeeb yaj kiab tsis sib xws, uas tsis tuaj yeem lees txais hauv ntau qhov kev siv siab - precision xws li kev tsim hluav taws xob hnub ci.
Txheej txheem Efficiency
Kev siv hluav taws xob zoo txo qis zog poob thaum lub sijhawm PECVD txheej txheem. Thaum lub nkoj ua hluav taws xob ua tau zoo, lub zog tsawg dua yog nkim thaum tshav kub, thiab muaj zog ntau dua rau cov ntshav plasma. Qhov no tsis tsuas yog txhim kho tag nrho cov kev ua tau zoo ntawm cov txheej txheem tab sis kuj txo cov nqi khiav lag luam.
Lub neej ntev ntawm lub nkoj Graphite
Kev tsim hluav taws xob tsim nyog yuav pab tswj xyuas qhov kev ncaj ncees ntawm lub nkoj graphite. Kev faib tawm tsis sib xws tuaj yeem ua rau muaj cua sov hauv zos, ua rau muaj kev ntxhov siab thermal thiab muaj peev xwm ua rau lub nkoj puas tsuaj. Los ntawm kev ua kom lub cev tsis sib xws, peb tuaj yeem txuas ntxiv lub neej kev pabcuam ntawm peb PECVD Graphite Boats, muab tus nqi zoo dua rau peb cov neeg siv khoom.
