Tus qauv thiab thermal celalivity ntawm pob zeb diamond

Pob zeb diamond yog cov qauv tsim cov qauv siv Crystal tsim los ntawm Kev Sib Tham ntawm Carbon atoms. Txhua tus muaj cov pa hluav taws xob ib qho kev sib cog lus muaj zog nrog ib puag ncig plaub atoms, uas muab pob tw ruaj khov thiab cov khoom siv lub cev tshwj xeeb.

 

Nws cov kev ua haujlwm thermal yog feem ntau yog raws li tus hu xov tooj kev ua kom zoo. Hauv Diamond muaju, qhov kev co ntawm cov roj carbon atoms hloov chaw kub hauv daim ntawv ntawm cov phonons ntawm cov suab. Vim yog cov ntawv sib cav muaj zog thiab cov qauv siv lead ua kom zoo nkauj hauv nws yog qhov tseem ceeb heev, thiab nws tuaj yeem hais tawm kub thaum kub heev. Tsis zoo li cov hlau, uas feem ntau tsuas yog cia siab rau dawb hauv hluav taws xob conduction, cov ntsuas phoo ua hauj lwm zoo vim yog hluav taws xob tawg, tsis zoo li cov hlau.
