Me yasa takarda graphite ke gudanar da wutar lantarki?
Saboda graphite ya ƙunshi cajin motsi kyauta, cajin yana motsawa cikin yardar kaina bayan lantarki don samar da halin yanzu, don haka zai iya gudanar da wutar lantarki. Ainihin dalilin da yasa graphite ke gudanar da wutar lantarki shine 6 carbon atoms suna raba 6 electrons don samar da babban haɗin ∏66 tare da electrons 6 da cibiyoyi 6. A cikin zoben carbon na wannan Layer na graphite, duk zoben membobi 6 suna samar da tsarin haɗin gwiwa. A wasu kalmomi, a cikin zoben carbon na wannan Layer na graphite, duk carbon atoms suna samar da babbar ∏ bond, kuma duk electrons a cikin wannan babban ∏ bond na iya gudana cikin yardar kaina a cikin Layer, wanda shine dalilin da ya sa takarda graphite zai iya gudanar da shi. wutar lantarki.
Graphite tsari ne na lamellar, kuma akwai na'urorin lantarki masu kyauta waɗanda ba a haɗa su tsakanin yadudduka ba. Bayan wutar lantarki, za su iya motsawa ta hanyar hanya. Kusan dukkan abubuwa suna gudanar da wutar lantarki, al'amarin juriya ne kawai. Tsarin graphite yana ƙayyade cewa yana da mafi ƙarancin juriya tsakanin abubuwan carbon.
Ƙa'idar aiki na takarda graphite:
Carbon kwayar zarra ce ta tetravalent. A gefe guda, kamar atom ɗin ƙarfe, mafi ƙarancin electrons suna ɓacewa cikin sauƙi. Carbon yana da mafi ƙarancin electrons. Yana da kama da karafa, don haka yana da wasu halayen lantarki. , za a samar da electrons kyauta da ramuka masu dacewa. Haɗe tare da na'urorin lantarki na waje waɗanda carbon zai iya ɓacewa cikin sauƙi, ƙarƙashin aikin yuwuwar bambance-bambance, za a sami motsi da cika ramukan. Ƙirƙirar kwararar electrons. Wannan shine ka'idar semiconductor.
