nkhani

Graphene imakhala ndi gawo limodzi la maatomu a kaboni opangidwa mu latisi ya hexagonal.Nkhaniyi ndi yosinthika kwambiri ndipo ili ndi zida zabwino kwambiri zamagetsi, zomwe zimapangitsa kuti zikhale zokopa pazinthu zambiri-makamaka zida zamagetsi.
Ofufuza motsogozedwa ndi Pulofesa Christian Schönenberger wa ku Swiss Institute of Nanoscience ndi dipatimenti ya Fizikisi ya University of Basel adaphunzira momwe angagwiritsire ntchitozamagetsi zamagetsi zamagetsi kudzera mukutambasula kwamakina.Kuti achite izi, adapanga chimango chomwe gawo la atomiki laling'ono la graphene limatha kutambasulidwa m'njira yoyendetsedwa ndikuyesa zinthu zake zamagetsi.

Pamene kupanikizika kumagwiritsidwa ntchito kuchokera pansi, chigawocho chidzapindika.Izi zimapangitsa kuti gawo la graphene lophatikizidwa kuti litalike ndikusintha mphamvu zake zamagetsi.

Masangweji pa alumali

Asayansi adayamba kupanga sangweji ya "sandwich" yokhala ndi graphene pakati pa zigawo ziwiri za boron nitride.Zigawo zomwe zimaperekedwa ndi magetsi zimagwiritsidwa ntchito ku gawo lapansi losinthika.

Kusintha kwamagetsiOfufuzawo adagwiritsa ntchito njira zowunikira kuti athe kuwongolera kutambasuka kwa graphene.Kenako anagwiritsa ntchito magetsi  miyeso yoyendera kuti muphunzire momwe mapindikidwe a graphene amasinthira mphamvu ya elekitironi.Izi  kuyeza kuyenera kuchitidwa paminus 269°C kuti muwone kusintha kwa mphamvu.

Chipangizo champhamvu champhamvu cha graphene chosasunthika ndi b strained (green shaded) graphene pamalo osalowerera ndale (CNP).  "Kutalikirana pakati pa nuclei kumakhudza mwachindunji makhalidwe a magetsi a graphene," Baumgartnermwachidule zotsatira."Ngati kutambasula kuli yunifolomu, kuthamanga kwa electron ndi mphamvu zokha zimatha kusinthamphamvu ndiye mphamvu ya scalar yomwe idanenedweratu ndi chiphunzitso, ndipo tatha kutsimikizira izizoyesera."  Ndizotheka kuti zotsatirazi zidzatsogolera ku chitukuko cha masensa kapena mitundu yatsopano ya transistors.Kuphatikiza apo,graphene, monga dongosolo lachitsanzo la zinthu zina ziwiri-dimensional, wakhala mutu wofunikira wofufuza padziko lonse lapansizaka zaposachedwapa.
