Cov khoom tseem ceeb ntawm pob zeb diamond laum me ntsis yog pob zeb diamond, uas yog ib qho ntawm cov khoom siv thermal conductivity, thiab nws thermal conductivity yog 5 npaug ntawm tooj liab. Pob zeb diamond atoms yog tsim los ntawm ib qho yooj yim carbon skeleton. Cov pob txha pob txha yog cov qauv molecular zoo tshaj plaws uas tuaj yeem hloov cov cua sov kom zoo. Feem ntau hais lus, cov ntaub ntawv uas muaj cov tshuaj lom neeg yooj yim thiab cov qauv molecular feem ntau muaj cov thermal conductivity siab. Qhov no yog vim li cas pob zeb diamond muaj qhov sib txawv thermal conductivity.
Lub thermal conductivity thiab resistivity ntawm pob zeb diamond laum khoom yog qhov siab tshaj plaws ntawm tag nrho cov khoom no. Siv cov yam ntxwv tseem ceeb no, tso cov yeeb yaj kiab nano-pob zeb diamond rau ntawm cov ntaub ntawv thiab qhov chaw ntawm cov khoom siv hluav taws xob tuaj yeem txo qhov loj ntawm lawv cov cua kub dissipation qhov chaw, uas tsis yog tsuas yog xav tau los daws qhov teeb meem ntawm cov teeb meem kev kub nyhiab, thiab tseem muaj peev xwm tsim tau. kev tsim tawm ntawm VLSI. Tsis tas li ntawd, kev siv pob zeb diamond zoo heev infrared nkag tuaj yeem txhim kho lub qhov rais infrared ntawm satellites thiab lub zog lasers. Nrog rau kev tsim kho tshiab tas mus li thiab kev txhim kho ntawm kev paub txog kev tswj hwm kev noj qab haus huv, cov pob zeb diamond yuav raug siv ntau thiab ntau yam ntawm lub neej.
Pob zeb diamond cov khoom yog ib qho tseem ceeb ntawm ntau yam khoom siv hluav taws xob niaj hnub, qhov chaw uas lawv tuaj yeem txhawb nqa cov cua sov thiab tswj cov khoom siv computer rhiab heev. Lub siab thermal conductivity ntawm pob zeb diamond kuj tseem pab txheeb xyuas qhov tseeb ntawm cov pob zeb diamond hauv cov hniav nyiaj hniav kub, ntxiv cov pob zeb diamond me me rau cov cuab yeej thiab cov tswv yim tuaj yeem muaj kev cuam tshuam loj rau thermal conductivity.
Lub thermal conductivity ntawm aluminium puas cov ntaub ntawv rau pob zeb diamond khoom nyob ntawm qhov loj ntawm cov txheej txheem kev npaj, yog li cov txheej txheem sib xyaw yog qhov tseem ceeb tshwj xeeb hauv kev tshawb fawb cov ntaub ntawv. Muaj ntau txoj hauv kev los npaj cov hlau matrix composites. Nrog rau kev txhim kho thev naus laus zis thiab khoom siv, ntau txoj hauv kev tshiab thiab cov txheej txheem tshiab tau maj mam muab tau. Tam sim no, cov txheej txheem kev npaj tseem ceeb ntawm pob zeb diamond alumina puas cov ntaub ntawv feem ntau suav nrog cov pa roj ntshav sintering, lub tshuab nqus tsev kub nias sintering, pressureless infiltration, nqus siab infiltration thiab kneading casting.
Lub thermal conductivity ntawm pob zeb diamond khoom yog ib qho tseem ceeb ntawm cov khoom siv thermal conductivity ntawm cov khoom sib xyaw. Lub thermal conductivity ntawm pob zeb diamond hais txog nws cov qauv siv lead ua thiab kev ncaj ncees. Synthetic hluavtaws pob zeb yuav tsum tau ntxiv ntawm hlau, npib tsib xee, cobalt thiab manganese raws li catalysts, uas yuav ua rau ib co impurities thiab tsis xws luag nyob rau hauv lub pob zeb diamond, thiab ces inevitably txo lub intrinsic thermal conductivity ntawm lub pob zeb diamond.
