Ha ho nepahale ho hang ho bolela hore graphite ke semiconductor. Mafapheng a mang a dipatlisiso tsa meedi, thepa ya khabone e kang di-nanotubes tsa khabone, difilimi tsa sefe ya dimolekhule tsa khabone le difilimi tsa khabone tse kang taemane (tseo boholo ba tsona di nang le thepa ya bohlokwa ya semiconductor tlasa maemo a itseng) ke tsathepa ea graphite, empa sebopeho sa tsona se senyenyane se fapane haholo le sebopeho se tloaelehileng sa graphite se nang le mekhahlelo.
Ho graphite, ho na le dielektrone tse nne lera le ka ntle la diathomo tsa khabone, tse tharo tsa tsona di etsa maqhama a covalent le dielektrone tsa diathomo tse ding tsa khabone, hoo athomo e nngwe le e nngwe ya khabone e nang le dielektrone tse tharo ho etsa maqhama a covalent, mme e setseng e bitswa dielektrone tsa π. Dielektrone tsena tsa π di tsamaya ka bolokolohi sebakeng se pakeng tsa dikarolo, mme ho tsamaisa ha graphite ho itshetlehile haholo ka dielektrone tsena tsa π. Ka mekgwa ya dikhemikhale, kamora hore khabone e ka hara graphite e fetolwe ntho e tsitsitseng, jwalo ka carbon dioxide, ho tsamaisa ha motlakase ho a fokola. Haeba graphite e oxidiswa, dielektrone tsena tsa π di tla theha maqhama a covalent le dielektrone tsa diathomo tsa oksijene, kahoo di ke ke tsa hlola di tsamaya ka bolokolohi, mme ho tsamaisa ha motlakase ho tla fokotseha haholo. Ena ke molao-motheo wa ho tsamaisa wamokhanni oa graphite.
Indasteri ea semiconductor e entsoe haholo-holo ka lipotoloho tse kopantsoeng, li-optoelectronics, li-apartator le li-sensor. Lisebelisoa tse ncha tsa semiconductor li hloka ho latela melao e mengata ho nkela thepa ea silicon ea setso sebaka le ho hapa kananelo ea 'maraka. Tšusumetso ea Photoelectric le phello ea Hall ke melao e 'meli ea bohlokoa ka ho fetisisa kajeno. Bo-rasaense ba hlokometse phello ea quantum Hall ea graphene mochesong oa kamore 'me ba fumane hore graphene e ke ke ea hlahisa ho hasana ka morao kamora ho kopana le litšila, ho bontšang hore e na le thepa e tsamaisang motlakase haholo. Ho phaella moo, graphene e batla e bonaletsa ka leihlo le hlobotseng 'me e na le ponahalo e phahameng haholo. Graphene e na le thepa e ntle ea optical 'me e tla fetoha ka botenya ba eona. E loketse ho sebelisoa tšimong ea optoelectronics. Graphene e na le thepa e mengata e ntle 'me e tla sebelisoa masimong a mangata, joalo ka skrine ea ponts'o, capacitor, sensor le tse ling.
