Melemo ea SWCNTs e sebelisoang ho Phekolo ea Likhoerekhoere:
Kopo: Ka lebaka la phapang ea bophara ba eona le angle ea helix, carbon nanotube e ka ba tšobotsi ea tšepe kapa tšobotsi ea semi-conductive.Kahoo, e ka e sebelisa ho etsa diode ea tekanyo ea limolek'hule, 'me diode e tla ba nyane joalo ka nanometer e nyane haholo ho feta ea bokahohleng hajoale.Carbon nanotube e na le matla a phahameng ka ho fetisisa, a matla ho feta tšepe.Ka nako e ts'oanang, carbon nanotube e bobebe haholo ka boima ba 'mele, e leng karolo ea leshome feela ea tšepe.E na le litebello tse ntle tsa ts'ebeliso lefapheng la lisebelisoa tse kopaneng 'me e tla ba le tšusumetso e kholo ho sefofane le sefofane.
Carbon nanotube e na le ts'ebetso e ntle ea tlhahiso ea masimong.E ka sebelisoa ho etsa sesebelisoa sa ho bonts'a liphanele tse bataletseng mme sebakeng sa mokhoa o moholo le o boima oa cathode electron tube.Ntle le moo, carbon nanotube le eona e ka sebelisoa ho etsa libering tsa molek'hule le roboto ea nano.E loketse ho sebelisoa e le lisebelisoa tsa polokelo ea matla joalo ka polokelo ea haedrojene.Ka mokhoa oa bongaka, e ka sebelisoa e le setshelo sa nano le ho fihlela taolo ea litekanyetso.
Carbon nano-tube ke nano grade tubular graphite crystals, e nang le monolayer kapa multilayer flakegraphite e pota-potileng shaft e bohareng ho latela mokhoa o itseng oa spiral angle curly le ho kena ka har'a seamless cylindrical tube.Ka lebaka la mohaho o khethehileng, e na le thepa e mengata e khethehileng 'me e ka sebelisoa ho lisebelisoa tsa elektronike, mechine, meriana, matla, lik'hemik'hale, optics le likarolo tse ling tsa saense ea thepa, hammoho le tšebeliso e ka sebelisoang masimong a meralo.Li bonts'a matla a sa tloaelehang le lisebelisoa tse ikhethang tsa motlakase, 'me ke li-conductors tse sebetsang hantle tsa mocheso.
Matla le ho feto-fetoha ha carbon nanotubes li etsa hore li sebelisoe ho laola mekhoa e meng ea nanoscale, e leng se bontšang hore li tla ba le karolo ea bohlokoa ho boenjiniere ba nanotechnology.
