Kwicrystallography, ulwakhiwo lwedayimani lukwabizwa ngokuba yi-diamond cubic crystal structure, eyenziwa kukudityaniswa kwe-covalent yee-athomu zekhabhoni.Uninzi lweempawu ezigqithisileyo zedayimani zisiphumo esithe ngqo se-sp³ covalent bond yamandla okwenza ulwakhiwo oluqinileyo kunye nenani elincinci le-athom zekhabhoni.I-Metal iqhuba ubushushu ngokusebenzisa ii-electron zamahhala, kwaye ukuhanjiswa kwayo okuphezulu kwe-thermal kuhambelana nokuhamba kombane ophezulu.Ngokwahlukileyo koko, ukuhanjiswa kobushushu kwidayimani kufezekiswa kuphela ngokungcangcazela kweeletisi (oko kukuthi, iiphonon).Iibhondi ezomeleleyo ezidityanisiweyo phakathi kweeathom zedayimani zenza ukuba ileti yekristale eyomeleleyo ibe nesantya esiphezulu sokungcangcazela, ke ngoko uphawu lwayo lobushushu lweDebye luphezulu ukuya kuthi ga kwi-2,220 K.

Ekubeni uninzi lwezicelo luphantsi kakhulu kunobushushu beDebye, ukusasazeka kwephonon kuncinci, ngoko ke ukuchasana nobushushu bokuqhuba kunye nephonon njengoko iphakathi incinci kakhulu.Kodwa nasiphi na isiphene se-lattice siya kuvelisa i-phonon yokusabalalisa, ngaloo ndlela kuncitshiswe i-thermal conductivity, elona phawu lwendalo yazo zonke izinto ze-crystal.Iziphene kwidayimani zihlala zibandakanya iziphene zamanqaku ezinje nge-ˡ³C isotopes enzima, ukungcola kwenitrogen kunye nezithuba, iziphene ezongeziweyo ezifana neziphene zokupakisha kunye nokususwa, kunye neziphene ze-2D ezifana nemida yeenkozo.

Ikristale yedayimani inesakhiwo esiqhelekileyo se-tetrahedral, apho zonke izibini ezi-4 zodwa ze-athomu zekhabhoni zinokwenza i-covalent bonds, ngoko ke akukho zi-electron zamahhala, ngoko ke idayimane ayikwazi ukuqhuba umbane.

Ukongeza, iiathom zekhabhoni kwidayimani zidityaniswe ziibhondi ezine-valent.Ngenxa yokuba ibhondi ye-CC kwidayimani yomelele kakhulu, zonke ii-electron ze-valence zithatha inxaxheba ekubunjweni kweebhondi ze-covalent, zenza i-pyramid-shaped crystal structure, ngoko ke ubulukhuni bedayimani buphezulu kakhulu kwaye indawo yokunyibilika iphezulu.Kwaye olu lwakhiwo lwedayimani lukwenza ukuba lufunxe iibhanti zokukhanya ezimbalwa kakhulu, uninzi lokukhanya olwenziwa kwidayimani lubonakaliswa ngaphandle, nangona lunzima kakhulu, lubonakala luselubala.

Okwangoku, izinto ezithandwa kakhulu zokutshatyalaliswa kobushushu ngamalungu entsapho ye-nano-carbon material, kubandakanywananodiamond, i-nano-graphene, i-graphene flakes, i-flake-shaped nano-graphite powder, kunye ne-carbon nanotubes.Nangona kunjalo, iimveliso zefilimu zokutshatyalaliswa kobushushu begraphite zendalo zityebile kwaye zine-conductivity ephantsi ye-thermal, ekunzima ukuhlangabezana neemfuno zokutshatyalaliswa kobushushu bexesha elizayo lamandla aphezulu, izixhobo ezidityanisiweyo eziphezulu.Ngaxeshanye, ayifikeleli kwiimfuno zabantu zokusebenza okuphezulu kokukhanya okugqithisileyo kunye nokubhityile, ubomi obude bebhetri.Ke ngoko, kubaluleke kakhulu ukufumana izixhobo ezitsha ze-super-thermal conductive.Oku kufuna ukuba izixhobo ezinjalo zibe nesantya esisezantsi kakhulu sokwandiswa kwe-thermal, i-ultra-high conductivity ye-thermal, kunye nokukhanya.Izixhobo zekhabhoni ezifana nedayimani kunye negraphene ziyahlangabezana neemfuno.Zine-conductivity ephezulu ye-thermal.Izinto zabo ezidibeneyo zihlobo lokuqhuba ubushushu kunye nezixhobo zokutshatyalaliswa kobushushu ezinomsebenzi omkhulu wesicelo, kwaye ziye zaba yingqwalasela.

Ukuba ungathanda ukwazi ngakumbi malunga nanodiamonds zethu, ngobubele uzive ukhululekile ukuqhagamshelana nabasebenzi bethu.
