Hazvina kururama kutaura kuti graphite is semiconductor. mune dzimwe nzvimbo dzekutsvagisa, kabhoni senge kabhoni nanotubes, kabhoni molecular sieve mafirimu uye madhaimondi-akafanana nekabhoni mafirimu (akawanda ayo ane akakosha semiconductor zvimiro pasi pemamwe mamiriro) ndeagraphite zvinhu, asi microstructure yavo yakasiyana zvakanyanya kubva kune yakajairwa layered graphite chimiro.
Mugraphite, mune maerekitironi mana ari kunze kwekabhoni atomu, matatu ayo anoumba covalent bond nemaerekitironi emamwe maatomu ecarbon, zvekuti atomu imwe neimwe kabhoni ine maerekitironi matatu kuti aumbe covalent bond, imwe yasara inonzi π electrons. . Aya maerekitironi anofamba anenge akasununguka munzvimbo iri pakati pezvikamu, uye mafambisirwo egraphite anonyanya kuenderana nemaerekitironi aya. Kuburikidza nemitoo yemakemikari, mushure mekunge kabhoni iri mugraphite yashandurwa kuita chinhu chakatsiga, senge kabhoni dhaibhoni, iyo conductivity inopera simba. Kana iyo graphite iine oxidized, maerekitironi aya π achagadzira covalent bond nemaerekitironi emaatomu eokisijeni, saka haakwanise kufamba akasununguka, uye conductivity ichadzikiswa zvakanyanya. Uyu ndiwo Conductive musimboti wegraphite conductor.
Iyo semiconductor indasitiri inonyanya kuumbwa neakasanganiswa maseketi, optoelectronics, separators uye sensors. Nyowani semiconductor zvinhu zvinoda kutevedzera mitemo yakawanda kutsiva zvechinyakare silicon zvinhu uye kuhwina musika kuzivikanwa. Photoelectric effect uye Hall effect ndiyo mitemo miviri inonyanya kukosha nhasi. Masayendisiti akacherekedza quantum Hall mhedzisiro yegraphene pakudziya kwekamuri uye vakawana kuti graphene haizoburitsa kumashure kupararira mushure mekusangana netsvina, zvichiratidza kuti ine super conductive properties.Pamusoro pezvo, graphene inenge iripachena neziso rakashama uye ine yakanyanya kujeka. Graphene ine yakanakisa optical zvimiro uye inochinja nekukora kwayo. Inokodzera kushandiswa mumunda we optoelectronics. Graphene ine zvakawanda zvakanaka zvivakwa uye ichashandiswa mundima dzakawanda, senge kuratidza skrini, capacitor, sensor uye zvichingodaro.
