Cov khoom thiab daim ntawv thov ntawm cov yeeb yaj kiab pob zeb diamond tshooj 2

Cov khoom siv hluav taws xob thiab daim ntawv thov ntawm cov yeeb yaj kiab pob zeb diamond
Pob zeb diamond kuj muaj qhov txwv tsis pub siv, muaj peev xwm nqa tau ntau, muaj cua sov zoo, muaj zog electron drift ntau, dielectric tsis tu ncua me me, muaj zog tawg ntau thiab muaj zog electron qhov, thiab lwm yam. Nws qhov hluav taws xob tawg ntau dua li Si thiab GaAs ob npaug, thiab nws qhov hluav taws xob thiab qhov muaj zog ntau dua li monocrystalline silicon CA:. Zaj duab xis pob zeb diamond siv tau ua cov khoom siv semiconductor broadband. Tam sim no, cov khoom siv no tau tshawb fawb txog silicon (cov khoom siv cuam tshuam thiab logic circuit), thiab cov khoom siv no siv tau rau hauv qhov kub qis dua 600 ℃, thiab muaj peev xwm siv tau rau hauv cov khoom siv semiconductor kub siab. Vim yog qhov sib txawv ntawm pob zeb diamond, nws siv tau rau kev tso tawm lub teeb xiav, kev ntes lub teeb ultraviolet, thiab cov khoom siv xau tsawg.

Cov Khoom Siv Kho Qhov Muag thiab Cov Ntawv Siv ntawm Cov Yeeb Yam Pob Zeb Diamond Nyias
Pob zeb diamond muaj cov khoom siv kho qhov muag zoo heev, ntxiv rau qhov muaj cov ncov me me (ua los ntawm kev co phonon) hauv 3 ~ 5μm, los ntawm sab nraud (225nm) mus rau qhov deb infrared (25μm) tag nrho cov kab, pob zeb diamond muaj kev xa mus siab, yog cov khoom siv qhov rai zoo tagnrho rau cov lasers infrared siab thiab cov khoom siv detectors. Pob zeb diamond hauv cov kab infrared ntawm kev pom tseeb kho qhov muag, ua rau nws dhau los ua cov khoom siv zoo tagnrho, tiv taus corrosion pem hauv ntej thauj los ntawm lub qhov rai kho qhov muag sab nraud hais tias cov khoom siv zoo tagnrho, tuaj yeem siv rau kev cuam tshuam ntawm lub qhov rai infrared hais tias. Tsis tas li ntawd, pob zeb diamond lub refractive index siab, tuaj yeem siv ua lub hnub lub roj teeb txo qis zaj duab xis. Radar nthwv dej nkag mus rau hauv pob zeb diamond zaj duab xis tsis yooj yim rau kev cuam tshuam, siv cov yam ntxwv no tuaj yeem siv ua radome, ya thiab foob pob hluav taws hauv supersonic ya, lub taub hau cone radar tsis tuaj yeem tiv taus qhov kub siab, thiab nyuaj rau tiv taus cov dej nag ceev ceev thiab hmoov av hla dhau, nrog. Pob zeb diamond ua rau hauv radome, tsis yog tsuas yog cua sov sai sai, hnav tsis kam zoo, tab sis kuj tuaj yeem daws qhov radome hauv kev ya ceev ceev kom tiv taus qhov teeb meem kub fusion siab.
Lwm yam kev siv ntawm pob zeb diamond zaj duab xis
Zaj duab xis pob zeb diamond muaj Young's modulus thiab elastic modulus siab, uas ua rau muaj kev sib kis ntawm cov suab nrov acoustic nrog kev ua haujlwm siab, thiab yog ib hom khoom siv tshiab rau kev ua cov ntxaij lim dej acoustic nthwv dej uas muaj kev nkag siab zoo heev. Pob zeb diamond muaj modulus elasticity siab thiab kev sib kis suab nrov ceev, thiab siv tau ua lub suab nrov zoo rau lub suab zoo.
Pob zeb diamond muaj cov modulus siab ntawm elasticity thiab kev kub ceev ntawm lub suab kis tau zoo, yog li nws tuaj yeem siv ua cov khoom siv vibration membrane rau lub suab nrov siab ntawm cov suab zoo.
Tsis tas li ntawd xwb, pob zeb diamond muaj kev ruaj khov zoo thiab tiv taus xeb los ntawm cov kua qaub tsis-oxidizing ntawm ntau qhov kub thiab txias. Nws cov khoom tseem ceeb, carbon, yog cov khoom tsis muaj tshuaj lom, tsis ua rau muaj kuab paug uas tsis ua rau lub cev tib neeg. Vim tias pob zeb diamond tsis ua rau cov ntshav tib neeg thiab lwm cov kua nqaij, pob zeb diamond kuj yog cov khoom siv kho mob zoo tshaj plaws, uas siv tau los ua cov twj tso kua plawv cuav.
