Cov khoom siv roj carbon - Cov roj carbon nanotubes

Cov pa roj carbon nanotube yog cov khoom siv ib-dimensional quantum nrog cov qauv tshwj xeeb (qhov radial dimension yog nano-scale, axial dimension yog micro-scale, thiab ob qhov kawg ntawm lub raj yog kaw). Seamless hollow nanoscale coaxial cylinder nrog ob qhov kawg kaw los ntawm fullerene hemispheres, carbon nanotubes yog lub npe hu ua qhov pheej hmoo tshaj plaws ib-seem nanomaterials nyob rau hauv lub xyoo pua 21st.

Thaum Lub Ib Hlis 20, 2017, American magazine tau luam tawm lub ntiaj teb kev ua tiav hauv kev ua haujlwm ntawm carbon nanotube electronics los ntawm Peng Lianmao ntawm Peking University thiab lwm tus: thawj qhov kev npaj ntawm cov pa roj carbon nanotube transistor nrog lub rooj vag ntev ntawm 5 nanometers, thiab ua pov thawj tias nws qhov kev ua tau zoo tshaj qhov qub Qhov loj ntawm silicon-based CMOS teb cov nyhuv transistors thawb transistor kev ua tau zoo mus rau qhov theoretical huab.
