Graphene e na le lera le le leng la liathomo tsa carbon tse hlophisitsoeng ka lesela la hexagonal.Boitsebiso bona bo bonolo haholo 'me bo na le thepa e babatsehang ea elektronike, e etsa hore e khahle lits'ebetso tse ngata-haholo-holo lisebelisoa tsa elektronike.
Bafuputsi ba etelletsoeng pele ke Moprofesa Christian Schönenberger ho tsoa Setsing sa Nanoscience sa Switzerland le Lefapha la Fisiks la Univesithi ea Basel ba ithutile mokhoa oa ho qhekella.thepa ea elektronike ea thepa ka ho otlolla mechine.E le ho etsa sena, ba ile ba theha moralo oo ka oona lesela le tšesaane la graphene le ka atolosoang ka mokhoa o laoloang ha le ntse le lekanya thepa ea eona ea elektronike.

Joale bafuputsi ba ile ba sebelisa wedge ho kenya khatello bohareng ba sandwich ho tloha tlase."Re e sebelisa ho koba likarolo ka mokhoa o laoloang le ho atolosa lera lohle la graphene," ho hlalositse mongoli oa pele Dr. Lujun Wang.
"Ho otlolla graphene ho re lumella ho khetha sebaka se pakeng tsa liathomo tsa carbon, kahoo re fetola matla a tsona a tlamang," ho phaella mofuputsi oa liteko Dr. Andreas Baumgartner.

"Sebaka se pakeng tsa nuclei se ama ka ho toba litšobotsi tsa libaka tsa elektronike ka graphene," Baumgartnera akaretsa liphetho."Haeba ho otlolla ho tšoana, ke lebelo la elektronike feela le matla a ka fetohangmatla ke bokhoni ba scalar bo boletsoeng esale pele ke khopolo, 'me joale re khonne ho paka sena ka botlaloliteko."
