1. Qhov Ceev ntawm Cov Khoom Siv: Qhov ceev ntawm cov khoom siv granite siv rau hauv kev tsim cov khoom granite yuav tsum nyob ib puag ncig 2.65g / cm3. Qhov no yog qhov ceev ntawm cov khoom siv granite ntuj, thiab nws ua kom muaj kev sib xws thiab kev ntseeg siab hauv cov khoom granite.

2. Kev tiaj tiaj: Kev tiaj tiaj yog ib qho ntawm cov lus qhia tseem ceeb tshaj plaws rau cov khoom siv granite siv rau hauv cov khoom siv semiconductor. Qhov tiaj tiaj ntawm qhov chaw granite yuav tsum qis dua 0.001 mm / m2. Qhov no ua kom ntseeg tau tias qhov chaw ntawm cov khoom yog tiaj tiaj thiab tiaj tus, uas yog qhov tseem ceeb rau cov txheej txheem tsim khoom semiconductor.

3. Kev Ua Kom Tiav Ntawm Qhov Chaw: Qhov ua kom tiav ntawm qhov chaw ntawm cov khoom granite yuav tsum zoo, nrog rau qhov roughness ntawm qhov chaw qis dua 0.4µm. Qhov no ua kom ntseeg tau tias qhov chaw ntawm cov khoom granite muaj qhov coefficient ntawm kev sib txhuam tsawg, uas yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm cov khoom siv semiconductor.

4. Tus lej nthuav dav ntawm thermal: Cov khoom siv semiconductor ua haujlwm ntawm qhov kub sib txawv, thiab cov khoom granite yuav tsum muaj peev xwm tiv taus qhov hloov pauv thermal yam tsis muaj kev hloov pauv. Tus lej nthuav dav thermal ntawm granite siv hauv cov khoom siv semiconductor yuav tsum qis dua 2 x 10 ^ -6 / ° C.

5. Kev kam rau qhov ntev: Kev kam rau qhov ntev yog qhov tseem ceeb rau kev ua haujlwm ntawm cov khoom granite. Kev kam rau qhov ntev ntawm cov khoom granite yuav tsum nyob hauv ± 0.1 hli rau txhua qhov ntev tseem ceeb.

6. Kev Nyuaj thiab Kev Tiv Thaiv Kev Hnav: Kev nyuaj thiab kev tiv thaiv kev hnav yog cov lus qhia tseem ceeb rau cov khoom siv granite siv rau hauv cov khoom siv semiconductor. Granite muaj qhov nyuaj ntawm Mohs Scale 6-7, ua rau nws yog cov khoom siv tsim nyog rau kev siv rau hauv cov ntawv thov khoom siv semiconductor.

7. Kev Ua Haujlwm Rwb Thaiv Tsev: Cov khoom siv granite siv rau hauv cov khoom siv semiconductor yuav tsum muaj kev ua haujlwm rwb thaiv tsev zoo heev kom tiv thaiv kev puas tsuaj rau cov khoom siv hluav taws xob rhiab heev. Kev tiv thaiv hluav taws xob yuav tsum siab dua 10 ^ 9 Ω / cm.

8. Kev Tiv Thaiv Tshuaj: Cov khoom siv granite yuav tsum tiv taus cov tshuaj siv feem ntau hauv cov txheej txheem tsim khoom semiconductor, xws li cov kua qaub thiab alkalis.

Xaus lus, cov qauv thiab cov lus qhia rau cov khoom siv granite siv rau hauv cov khoom siv semiconductor yog qhov tseem ceeb kom ntseeg tau tias lub neej ntev thiab kev ntseeg siab ntawm ob qho tib si cov khoom siv thiab cov khoom siv uas lawv siv. Cov lus qhia saum toj no yuav tsum tau ua raws li thaum lub sijhawm tsim qauv, tsim khoom, thiab teeb tsa kom ntseeg tau tias cov khoom siv zoo tshaj plaws. Los ntawm kev ua raws li cov qauv thiab cov lus qhia no, cov chaw tsim khoom semiconductor tuaj yeem ua kom ntseeg tau tias lawv cov khoom siv ua haujlwm zoo tshaj plaws, ua rau muaj kev tsim khoom thiab kev ua lag luam ntau ntxiv.
