Cov khoom siv semiconductor tau dhau los ua qhov chaw nyob hauv cov thev naus laus zis niaj hnub no, muab zog rau txhua yam los ntawm cov xov tooj ntse mus rau cov tsheb fais fab. Raws li qhov kev thov rau cov khoom siv hluav taws xob zoo dua thiab muaj zog ntxiv mus ntxiv, cov thev naus laus zis semiconductor tseem hloov pauv tas li, nrog cov kws tshawb fawb tshawb nrhiav cov ntaub ntawv tshiab thiab cov qauv uas tuaj yeem muab kev ua tau zoo dua. Ib qho khoom siv uas nyuam qhuav tau txais kev saib xyuas rau nws lub peev xwm hauv cov khoom siv semiconductor yog granite. Txawm hais tias granite yuav zoo li yog qhov kev xaiv txawv txawv rau cov khoom siv semiconductor, nws muaj ntau yam khoom uas ua rau nws yog qhov kev xaiv zoo. Txawm li cas los xij, kuj tseem muaj qee qhov kev txwv uas yuav tsum xav txog.
Granite yog ib hom pob zeb igneous uas muaj cov minerals xws li quartz, feldspar, thiab mica. Nws paub txog nws lub zog, kev ruaj khov, thiab kev tiv thaiv kev hnav thiab rhuav, ua rau nws yog cov khoom siv hauv tsev nrov rau txhua yam los ntawm cov cim tseem ceeb mus rau cov txee hauv chav ua noj. Nyob rau xyoo tas los no, cov kws tshawb fawb tau tshawb nrhiav lub peev xwm ntawm kev siv granite hauv cov khoom siv semiconductor vim nws cov thermal conductivity siab thiab cov coefficient thermal expansion qis.
Kev ua kom sov yog lub peev xwm ntawm cov khoom siv los ua kom sov, thaum cov coefficient ntawm kev nthuav dav thermal yog hais txog qhov ntau npaum li cas cov khoom siv yuav nthuav dav lossis cog lus thaum nws qhov kub hloov pauv. Cov khoom no tseem ceeb heev rau cov khoom siv semiconductor vim tias lawv tuaj yeem cuam tshuam rau kev ua haujlwm zoo thiab kev ntseeg siab ntawm lub cuab yeej. Nrog nws cov thermal conductivity siab, granite muaj peev xwm tso cua sov sai dua, uas tuaj yeem pab tiv thaiv kev kub dhau thiab ua kom lub neej ntawm lub cuab yeej ntev dua.
Lwm qhov zoo ntawm kev siv granite hauv cov khoom siv semiconductor yog tias nws yog cov khoom siv uas tshwm sim los ntawm ntuj, uas txhais tau tias nws yooj yim nrhiav tau thiab pheej yig dua piv rau lwm cov khoom siv ua tau zoo xws li pob zeb diamond lossis silicon carbide. Tsis tas li ntawd, granite ruaj khov hauv tshuaj lom neeg thiab muaj qhov dielectric tsis tu ncua qis, uas tuaj yeem pab txo qhov poob ntawm cov teeb liab thiab txhim kho kev ua haujlwm ntawm cov khoom siv.
Txawm li cas los xij, kuj tseem muaj qee qhov kev txwv uas yuav tsum xav txog thaum siv granite ua cov khoom siv semiconductor. Ib qho ntawm cov teeb meem tseem ceeb yog kev ua tiav cov qauv crystalline zoo. Vim tias granite yog pob zeb uas tshwm sim ntuj, nws tuaj yeem muaj cov khoom tsis huv thiab cov qhov tsis zoo uas tuaj yeem cuam tshuam rau cov khoom siv hluav taws xob thiab kho qhov muag ntawm cov khoom siv. Ntxiv mus, cov khoom ntawm ntau hom granite tuaj yeem sib txawv ntau, uas tuaj yeem ua rau nws nyuaj rau tsim cov khoom siv sib xws, txhim khu kev qha.
Lwm qhov teeb meem nrog kev siv granite hauv cov khoom siv semiconductor yog tias nws yog cov khoom siv uas tsis yooj yim tawg piv rau lwm cov khoom siv semiconductor xws li silicon lossis gallium nitride. Qhov no tuaj yeem ua rau nws yooj yim tawg lossis tawg thaum muaj kev ntxhov siab, uas tuaj yeem ua rau muaj kev txhawj xeeb rau cov khoom siv uas raug kev ntxhov siab lossis kev poob siab.
Txawm hais tias muaj cov teeb meem no los xij, cov txiaj ntsig ntawm kev siv granite hauv cov khoom siv semiconductor tseem ceeb txaus uas cov kws tshawb fawb tseem tab tom tshawb nrhiav nws lub peev xwm. Yog tias cov teeb meem no tuaj yeem kov yeej tau, nws muaj peev xwm hais tias granite tuaj yeem muab txoj hauv kev tshiab rau kev tsim cov khoom siv semiconductor ua haujlwm tau zoo, pheej yig uas ruaj khov dua li cov khoom siv ib txwm muaj.
Xaus lus, thaum muaj qee qhov kev txwv rau kev siv granite ua cov khoom siv semiconductor, nws cov thermal conductivity siab, thermal expansion coefficient qis, thiab dielectric tsis tu ncua qis ua rau nws yog qhov kev xaiv zoo rau kev tsim khoom siv yav tom ntej. Los ntawm kev daws cov teeb meem cuam tshuam nrog kev tsim cov qauv crystalline zoo thiab txo qhov brittleness, nws muaj peev xwm hais tias granite tuaj yeem dhau los ua cov khoom siv tseem ceeb hauv kev lag luam semiconductor yav tom ntej.
