Graphene wuxuu ka kooban yahay hal lakab oo atamka kaarboon ah oo lagu habeeyay shabag saddex geesood ah.Qalabkani waa mid aad u jilicsan wuxuuna leeyahay sifooyin elektaroonik ah oo aad u fiican, taas oo ka dhigaysa mid soo jiidasho leh codsiyo badan - gaar ahaan qaybaha elektaroonigga ah.
Cilmi-baarayaal uu hoggaaminayay Professor Christian Schönenberger oo ka socday Machadka Nanoscience ee Swiss-ka iyo Waaxda Fiisigiska ee Jaamacadda Basel ayaa daraasad ku sameeyay sida loo maamulosifooyinka elektarooniga ah ee alaabta iyada oo loo marayo kala-bixinta farsamada.Si taas loo sameeyo, waxay sameeyeen qaab-dhismeed kaas oo lakabka graphene ee khafiifka ah loo kala bixin karo si la kontaroolo iyadoo la cabbirayo sifooyinkiisa elegtarooniga ah.
Marka cadaadiska hoos laga soo rogo, qaybtu way soo laaban doontaa.Tani waxay keenaysaa in lakabka graphene ee ku xidhan uu sii dheeraado oo beddelo sifooyinka korantada.
Sandwiches on shelf
Saynis yahanadu waxay markii hore soo saareen sandwich "sandwich" leh lakabka graphene inta u dhaxaysa laba lakab oo boron nitride ah.Qaybaha lagu bixiyo xidhiidhada korantada waxaa lagu dabaqaa substrate dabacsan.
Xaaladda elegtarooniga ah ee la beddelayCilmi-baadhayaashu waxay markii hore isticmaaleen hababka indhaha si ay u cabbiraan fiditaanka graphene.Kadibna waxay isticmaaleen koronto cabbirrada gaadiidka si loo barto sida qallafsanaanta graphene u beddelo tamarta elektarooniga ah.Kuwaas cabbirada waxa loo baahan yahay in la sameeyo marka laga jaro 269°C si loo arko isbedelada tamarta.
Jaantusyada heerka tamarta qalabka ee graphene aan cidhiidhi ahayn iyo b xayndaab (hadhka cagaaran) graphene ee barta dhexdhexaadka ah ee kharashka (CNP). "Masaafada u dhaxaysa nuclei waxay si toos ah u saameynaysaa sifooyinka dawladaha elektiroonigga ah ee graphene," Baumgartnersoo koobay natiijada."Haddii kala bixidu ay labis tahay, kaliya xawaaraha elektarooniga ah iyo tamarta ayaa isbedeli kara. IsbeddelkaTamartu asal ahaan waa awoodda scalar ee ay saadaalisay aragtida, waxaana hadda awoodnay inaan taas ku caddaynnotijaabooyin." Waxaa la qiyaasi karaa in natiijooyinkani ay horseedi doonaan horumarinta dareemayaasha ama noocyada cusub ee transistors.Intaa waxaa dheer,graphene, oo ah nidaamka moodeelka agabka kale ee laba-geesoodka ah, wuxuu noqday mawduuc cilmi-baaris oo muhiim ah adduunka oo dhansanadihii ugu dambeeyay.
