Kungani iphepha le-graphite liqhuba ugesi? Iyini isimiso?

Kungani iphepha le-graphite lihambisa ugesi?

Ngenxa yokuthi i-graphite inamashaji ahamba ngokukhululeka, amashaji ahamba ngokukhululeka ngemva kokufakelwa ugesi ukuze akhe ugesi, ukuze akwazi ukudlulisa ugesi. Isizathu sangempela sokuthi i-graphite idlulise ugesi ukuthi ama-athomu e-carbon ayi-6 abelana ngama-electron ayi-6 ukuze akhe isibopho esikhulu esingu-∏66 nama-electron ayi-6 kanye nezikhungo eziyi-6. Endandatho yekhabhoni yesendlalelo esifanayo se-graphite, wonke amasongo anamalungu ayi-6 akha uhlelo oluhlanganisiwe lwe-∏-∏. Ngamanye amazwi, endandatho yekhabhoni yesendlalelo esifanayo se-graphite, wonke ama-athomu e-carbon akha isibopho esikhulu esikhulu esingu-∏, futhi wonke ama-electron akulesi sibopho esikhulu esingu-∏ angageleza ngokukhululeka esendlaleloni, okuyisizathu esenza iphepha le-graphite likwazi ukudlulisa ugesi.

I-Graphite iyisakhiwo se-lamellar, futhi kukhona ama-electron akhululekile angaboshiwe phakathi kwezingqimba. Ngemva kokufakwa kukagesi, angahamba ngendlela ethile. Cishe zonke izinto ziphehla ugesi, kumane kuyindaba yokumelana. Isakhiwo se-graphite sinquma ukuthi inokumelana okuncane kakhulu phakathi kwezinto zekhabhoni.

Isimiso sokuqhuba iphepha le-graphite:

I-Carbon iyi-athomu ye-tetravalent. Ngakolunye uhlangothi, njengama-athomu ensimbi, ama-electron angaphandle alahleka kalula. I-Carbon inama-electron ambalwa angaphandle. Ifana kakhulu nezinsimbi, ngakho-ke inokuqhuba okuthile kukagesi. , ama-electron amahhala ahambisanayo kanye nemigodi kuzokhiqizwa. Uma kuhlanganiswa nama-electron angaphandle i-carbon engawalahla kalula, ngaphansi kwesenzo somehluko ongaba khona, kuzoba nokunyakaza nokugcwalisa imigodi. Dala ukugeleza kwama-electron. Lesi yisimiso sama-semiconductor.
