Gripherine ine denderedzwa rimwechete maatomu maatomu akarongwa mune yeheti yehexagonil. Izvi zvinyorwa zvinoshanduka uye zvine zvivakwa zvakanaka zvemagetsi, zvichiita kuti zvinakidze kune akawanda mashandisirwo-kunyanya ezvikamu zvemagetsi.
Vanotsvagurudza vakatungamirwa naProfesa Christian Schönenberger kubva kuSwitzerland of Nanoscience neDhipatimendi reFizits yeNhivhesa yeBasel yakadzidza nzira yekunyorazvemagetsi zvemagetsi zvezvinhu kuburikidza nekufambisa kwemuchina.Kuti vaite izvi, vakagadzira chimiro chakaburitswa neyekutakura graphere yemugodhi inogona kutambanudzwa nenzira inodzorwa nenzira inoyera zvivakwa zvemagetsi.
Kana dzvinyiriro ikashandiswa kubva pazasi, chikamu chinokotama. Izvi zvinokonzeresa grapheyed grapheene layer kuti ibudise uye shandura zvivakwa zvemagetsi.
Sandwiches pasherufu
Masayendisiti akatanga kuburitsa "sandwich" sangweji ine denderedzwa reGriphene pakati pezvikamu zviviri zveBoron nitride. Izvo zvikamu zvakapihwa nemagetsi ekutaurirana zvinoiswa kune iyo inoshanduka substrate.
Yakachinja mamiriro emagetsiVatsvagiri vakatanga kushandisa nzira dzechokwadi kuti vatambanudzire griyenji. Ivo vakabva vashandisa magetsi Kufambisa zviyero zvekudzidza kuti kusvibiswa kweGriphene kunoshandura sei simba emagetsi. Izvi Zviyero zvinoda kuitwa kuMinus 269 ° C kuti uone shanduko yesimba.
Chishandiso Chishandiso Level Diagrams yeGrapheni Graphene uye B Yakatemerwa (Green Shaded) Graphene panzvimbo yekusarerekera (CNP). "Chinhambwe pakati peiyo nuclei chinokanganisa hunhu hwenyika dzemagetsi muGriphene," BaumgartnerPfupiso mhedzisiro. "Kana kutambanudzwa kwacho kwunifomu, chete ekumhanya kwemagetsi uye simba rinogona kuchinja. Shanduko yachosimba ndere kunyatsoenderana kwekufungidzira kwakafanotaurwa nedzidziso, uye isu tava kugona kuratidza izvi kuburikidzakuedza. " Izvo zvinofungidzirwa kuti aya mhedzisiro ichatungamira mukuvandudzwa kwevanonzwisisa kana marudzi matsva evatengesi. Pamusoro pe,Grapheene, senzira yemuenzaniso yezvimwe zvinhu zviviri-zviyero, zvave musoro wakakosha wekutsvagisa pasi rese mukatiMakore achangopfuura.
