Ha hoa nepahala haholo ho bolela hore graphite ke semiconductor. mafapheng a mang a lipatlisiso, lisebelisoa tsa carbon tse kang carbon nanotubes, lifilimi tsa carbon molecular sieve le lifilimi tsa carbon tse kang taemane (tseo boholo ba tsona li nang le litšobotsi tsa bohlokoa tsa semiconductor tlas'a maemo a itseng) ke tsalisebelisoa tsa graphite, empa microstructure ea bona e fapane haholo le sebopeho se tloaelehileng sa graphite.
Ka graphite, ho na le lielektrone tse 'nè karolong e ka ntle ea liathomo tsa carbon, tse tharo tsa tsona li theha maqhama a covalent le lielektrone tsa liathomo tse ling tsa carbon, e le hore athomo e' ngoe le e 'ngoe ea k'habone e na le lielektrone tse tharo ho theha likamano tse kopanetsoeng,' me e setseng e bitsoa π electrons. . Li-electrone tsena tsa π li tsamaea ka bolokolohi sebakeng se pakeng tsa lihlopha, 'me conductivity ea graphite e itšetlehile haholo ka li-electrone tsena. Ka mekhoa ea lik'hemik'hale, ka mor'a hore carbon e graphite e fetohe ntho e tsitsitseng, e kang carbon dioxide, conductivity ea fokotseha. Haeba graphite e na le oxidized, li-electrone tsena tsa π li tla theha maqhama a covalent le lielektrone tsa liathomo tsa oksijene, kahoo li ke ke tsa hlola li tsamaea ka bolokolohi, 'me conductivity e tla fokotseha haholo. Ena ke molao-motheo oa Conductive oamokhanni oa graphite.
Indasteri ea semiconductor haholo-holo e entsoe ka lipotoloho tse kopaneng, li-optoelectronics, li-separators le li-sensor. Lisebelisoa tse ncha tsa semiconductor li hloka ho latela melao e mengata ho nka sebaka sa lisebelisoa tsa silicon tsa setso le ho hapa kananelo ea 'maraka. Photoelectric effect le Hall effect ke melao e 'meli ea bohlokoa ka ho fetisisa kajeno. Bo-rasaense ba ile ba hlokomela phello ea quantum Hall ea graphene mocheso oa kamore 'me ba fumana hore graphene e ke ke ea hlahisa ho hasana ka morao ka mor'a ho kopana le litšila, e leng se bontšang hore e na le thepa e phahameng ea conductive. Graphene e na le thepa e ntle ea optical mme e tla fetoha ka botenya ba eona. E loketse ho sebelisoa tšimong ea optoelectronics. Graphene e na le thepa e ngata e ntle haholo 'me e tla sebelisoa likarolong tse ngata, joalo ka skrineng, capacitor, sensor joalo-joalo.
