Dab tsi yog Graphene khoom

Graphene yog thinnest thiab cov ntaub ntawv haib tshaj plaws kom pom deb. Nyias vim hais tias graphene yog li ntawm carbon atoms ntawm ob-qhov muaju, lub thickness ntawm tsuas yog ib qho atom. Txawm hais tias nyias nyias mus rau huab, tab sis tuab heev, txawm tias lub me me me me atom atom loj ntawm helium tsis tau mus rau nws.

Graphene yog dab tsi? Graphene yog honeycomb planar zaj duab xis ua los ntawm sp2 hybridization ntawm cov atoms. Nws yog ib yam khoom siv uas muaj plaub-ob sab uas tsuas muaj ib qho piv txwv atomic tab, ces nws tseem hu ua monatomic txheej graphite. Nws cov thickness yog li 0.335nm, raws li qhov sib txawv ntawm ntau lawm muaj ntau qhov sib txawv thiab downs, feem ntau nyob rau ntawm txoj kev ntsuas ntawm qhov siab txog 1nm, kab rov tav ntawm 10nm rau 25nm, yog ntxiv rau txhua cov pa siv lead ua ( Cov voj voog tas li, ib-dimensional carbon nanotubes, peb-dimensional kom graphite).

Ntev dhau los ua ntej muaj ib tus kws kho mob hauv kev tshawb xav los kwv yees, quas-ob-qhov sib luag ua rau nws tus kheej thermodynamic xwm ntawm kev tsis haum, hauv chav tsev sov yuav sai sai los yog curled, ces nws tsis muaj nyob ib leeg.

Mus txog 2004, British University of Manchester physicist Andrei Gem thiab Constantine Novo Shuo Luofu, nrog micro-mechanical stripping txoj kev ntse cais los ntawm graphite graphene, paub tseeb tias nws muaj nyob ib leeg, rau graphene Ntawm kev tshawb fawb pib ua kom nquag plias Yeej xyoo 2010 Nobel txeeb hauv Physics.

Daim ntawv cog lus feem ntau ntawm graphene yog hloov ntawm silicon, ua ultra-minimal transistors rau ntau lawm ntawm supercomputers yav tom ntej. Nrog graphene tsis silicon, lub tshuab computer yuav khiav ntau pua lub sij hawm sai dua.

Tsis tas li, graphene yuav luag tag nrho, tsuas yog nqus 2.3% ntawm lub teeb. Ntawm qhov tod tes, nws yog tuab heev, txawm tias cov roj me me feem ntau (helium) tsis tuaj yeem nkag mus. Cov nta no ua rau nws zoo siv los ua cov khoom hluav taws xob, xws li lub vijtsam tsho, lub teeb-emitting vaj huam sib luag thiab lub vaj huam sib luag hnub ci.

Graphene hu ua "dub kub" thiab "huab tais cov ntaub ntawv tshiab", cov kws tshawb fawb txawm hais tias graphene yuav "pauv tag nrho tiam 21st century" Nws yog feem ntau yuav tsim teebmeem Tawm lub thoob ntiaj teb kev cuam tshuam tshiab technology thiab tshiab kiv puag ncig.
