Nws yog qhov zoo tshaj plaws pob tshab, absorbing tsuas yog 2.3 feem pua ntawm lub teeb uas tsaws rau ntawm nws, tab sis yog koj muaj ib daim ntawv dawb los muab piv rau, koj tuaj yeem pom tias nws nyob ntawd. Qhov ntawd txhais tau tias koj tuaj yeem pom ib txheej ntawm atom nrog koj qhov muag liab qab, yog lawv yog graphene.

Khaws qhov no hauv kev xav, graphene puas tuaj yeem pob tshab?

Graphene yog xwb pob tshab vim nws nyias nyias (ib atom tuab). Yog hais tias nws absorbs 2% ib txheej ces tsuas yog ob peb puas khaubncaws sab nraud povtseg yuav nqus yuav luag tag nrho cov teeb thiab qhov tseem yuav yog ib daim ntawv nyias heev ntawm graphite. Qhov no ua rau nws muaj peev xwm forelectrons txav mus los ntawm ib daim ntawv graphene rau conductelectricity.

Ib tug kuj nug, puas yog graphite tib yam li graphene? Graphene tsuas yog ib txheej atomic ntawm graphite - ib txheej ntawm sp2 bonded carbon atoms teem nyob rau hauv ahexagonal los yog honeycomb lattice. Graphite yog ib qho feem ntau pommineral thiab yog tsim los ntawm ntau txheej ntawm graphene . Kev tsim kho ntawm ob qho tib si graphene thiab graphite , thiab lawv txoj kev fabrication txawv me ntsis.

Tsis tas li ntawd, dab tsi yog graphene siv rau tam sim no?

Muaj peev xwm graphene Cov ntawv thov suav nrog lub teeb yuag, nyias, thiab hloov pauv hluav taws xob / photonics circuits, solarcells, thiab ntau yam kev kho mob, tshuaj thiab kev lag luam txheej txheem tsim kho lossis qhib los ntawm kev siv cov tshiab graphene cov ntaub ntawv. Los ntawm 2017, graphene electronics tau raug tsim nyob rau hauv kev lag luam fab ntawm 200 mm kab.

Dab tsi yog qhov tshwj xeeb ntawm graphene?

Graphene tsuas yog atom-tuab tab sis yog immenselystrong thiab saj zawg zog ib yam nkaus . Nws yog ib qho yooj yim los rub thiab ncab cov ntaub ntawv nyob ib ncig ntawm 25% ntawm nws qhov ntev ntev yam tsis muaj kev puas tsuaj. Nws yog ua tau vim hais tias lub tiaj tus, dav hlau qauv ntawm cov khoom yog ntau yam ntuj tso rau flex, tsis ua txhaum lub atomic bonds ntawm nws cov molecules.
