Faa'iidooyinka SWCNT-yada loo isticmaalo daawaynta bulaacadaha:
Codsiga: Farqiga u dhexeeya dhexroorkiisa iyo xagasha helix-ka awgeed, nanotube kaarboon wuxuu noqon karaa sifo macdan ah ama sifo-conductive ah.Markaa, waxa uu u isticmaali karaa in uu sameeyo diode-cabbir-molecular, diode-kuna waxa uu noqon doonaa sida nanometer oo kale oo aad uga yar kan caalamiga ah ee hadda.Kaarboon nanotube ayaa leh xoogga ugu sarreeya, kaas oo aad uga xoog badan birta.Isla mar ahaantaana, kaarboon nanotube miisaankiisu aad buu u yar yahay, kaas oo ah toban meelood meel oo keliya birta.Waxay leedahay aragtiyo codsi oo weyn oo ku saabsan agabka isku dhafan waxayna saameyn weyn ku yeelan doontaa hawada hawada iyo hawada sare.
Kaarboon nanotube waxa ay leedahay wax qabad aad u wanaagsanWaxaa loo isticmaali karaa samaynta qalabka bandhiga flat panel iyo halkii farsamada tube electron ee cathode weyn oo culus.Ka sokow, kaarboon nanotube sidoo kale waxaa loo isticmaali karaa samaynta xadhkaha molecule iyo nano robot.Way ku habboon tahay in loo isticmaalo sida walxaha kaydinta tamarta sida kaydinta hydrogen.Farsamada daawada, waxaa loo isticmaali karaa sidii weel nano iyo si loo gaaro xakameynta qiyaasta.
Kaarboon nano-tube waa kiristaalo nano grade tubular graphite crystals, kaas oo ka kooban monolayer ama flakegraphite multilayer kaas oo ku hareeraysan usheeda dhexe iyadoo loo eegayo xagasha wareega qaarkeed oo galay tuubada cylindrical ee aan fiicneyn.Sababtoo ah dhismo gaar ah, waxay leedahay sifooyin gaar ah oo badan waxaana loo isticmaali karaa qalabka elektiroonigga ah, mishiinada, daawada, tamarta, kiimikooyinka, optics iyo qaybaha kale ee sayniska qalabka, iyo sidoo kale isticmaalka suurtagalka ah ee goobaha dhismaha.Waxay soo bandhigaan xoog aan caadi ahayn iyo sifooyin koronto oo gaar ah, waana kirishtaan kuleyl oo hufan.
Awoodda iyo dabacsanaanta kaarboon nanotubes waxay ka dhigaysaa isticmaalka suurtagalka ah ee lagu xakameynayo qaababka kale ee nanoscale, taas oo soo jeedinaysa inay door muhiim ah ku yeelan doonaan injineernimada nanotechnology.
