Ho crystallography, sebopeho sa daemane se boetse se bitsoa "diamane cubic crystal structure", e thehiloeng ke ho tlamahanngoa ha liathomo tsa carbon.Bongata ba thepa e feteletseng ea taemane ke phello e tobileng ea sp³ covalent bond matla a etsang sebopeho se thata le palo e nyane ea liathomo tsa carbon.Metal e tsamaisa mocheso ka li-electrone tse sa lefelloeng, 'me mocheso oa eona o phahameng oa mocheso o amahanngoa le motlakase o phahameng oa motlakase.Ka lehlakoreng le leng, ho tsamaisa mocheso ka daemane ho finyelloa feela ka ho thothomela ha lattice (ke hore, lifonomo).Maqhama a matla haholo a covalent lipakeng tsa liathomo tsa daemane a etsa hore lesela le thata la kristale le be le maqhubu a phahameng a ho sisinyeha, kahoo mocheso oa eona oa Debye o phahame joalo ka 2,220 K.

 

Kaha lits'ebetso tse ngata li tlase haholo ho feta mocheso oa Debye, ho hasana ha phonon ho nyane, kahoo ho hanyetsa mocheso oa mocheso le phonon ha seaplane se le senyenyane haholo.Empa sekoli leha e le sefe sa lattice se tla hlahisa ho hasana ha phonon, ka hona ho fokotsa conductivity ea mocheso, e leng tšobotsi ea tlhaho ea lisebelisoa tsohle tsa kristale.Mefokolo ea taemane hangata e kenyelletsa mefokolo ea lintlha joalo ka li-isotopi tse boima tsa ˡ³C, litšila le likheo tsa naetrojene, likoli tse atolositsoeng joalo ka liphoso tsa ho bokellana le ho kheloha, le bofokoli ba 2D joalo ka meeli ea lijo-thollo.

 

Kristale ea daemane e na le sebopeho se tloaelehileng sa tetrahedral, moo lipara tse 4 tse le 'ngoe tsa liathomo tsa carbon li ka etsang li-covalent bond, kahoo ha ho na li-electrone tsa mahala, kahoo daemane ha e khone ho tsamaisa motlakase.

 

Ho phaella moo, liathomo tsa carbon tse taemane li hokahanngoa ke li-bond tse 'nè.Hobane tlamo ea CC ka daemane e matla haholo, li-electrone tsohle tsa valence li kenya letsoho ho thehoeng ha litlamo tsa covalent, ho etsa sebopeho sa kristale se nang le piramide, kahoo boima ba daemane bo phahame haholo 'me ntlha ea ho qhibiliha e phahame.'Me sebopeho sena sa daemane se boetse se etsa hore e monye lihlopha tse fokolang haholo tsa leseli, boholo ba leseli le khantšitsoeng holim'a daemane le bonahatsoa ka ntle, kahoo le hoja le le thata haholo, le shebahala le hlakile.

 

Hona joale, lisebelisoa tse ratoang haholo tsa ho senya mocheso ke haholo-holo litho tsa lelapa la thepa ea nano-carbon, ho kenyeletsananodiamond, nano-graphene, graphene flakes, nano-graphite phofo e bōpehileng joaloka flake, le carbon nanotubes.Leha ho le joalo, lihlahisoa tsa filimi tsa tlhaho tsa graphite tse senyang mocheso li tebile ebile li na le conductivity e tlaase ea mocheso, eo ho leng thata ho finyella litlhoko tsa ho senya mocheso oa lisebelisoa tsa nakong e tlang tsa matla a phahameng, a holimo-limo a kopantsoeng.Ka nako e ts'oanang, ha e finyelle litlhoko tsa batho tsa ts'ebetso e phahameng bakeng sa bophelo ba betri bo bobebe le bo bobebe, bo bolelele.Ka hona, ho bohlokoa haholo ho fumana lisebelisoa tse ncha tsa super-thermal conductive.Sena se hloka hore lisebelisoa tse joalo li be le sekhahla se tlase haholo sa katoloso ea mocheso, conductivity e phahameng ea mocheso, le bobebe.Lisebelisoa tsa carbon tse kang taemane le graphene li finyella litlhoko.Li na le conductivity e phahameng ea mocheso.Lisebelisoa tsa bona tse kopantsoeng ke mofuta oa ho tsamaisa mocheso le lisebelisoa tsa ho senya mocheso tse nang le bokhoni bo boholo ba kopo, 'me li fetohile tse lebisang tlhokomelo.

 

Haeba u ka rata ho tseba haholoanyane ka li-nanodiamond tsa rona, ka mosa ikutloe u lokolohile ho ikopanya le basebetsi ba rona.
