He paparanga kotahi o ngā ngota waro kei roto i te graphene, kua whakaritea ki roto i te whatunga hexagonal. He tino ngāwari tēnei rauemi, ā, he tino pai ngā āhuatanga hiko, e ātaahua ai mō ngā tono maha—ina koa ko ngā wāhanga hiko.
I rangahauhia e ngā kairangahau i arahina e Ahorangi Christian Schönenberger mai i te Swiss Institute of Nanoscience me te Tari Ahupūngao o te Whare Wānanga o Basel me pēhea te whakahaere i tengā āhuatanga hiko o ngā rauemi mā te totoro ā-pūkaha.Hei whakatutuki i tēnei, i whakawhanakehia e rātou he anga e taea ai te totoro i te paparanga graphene angiangi ā-atomika i roto i te huarahi whakahaere i te wā e ine ana i ōna āhuatanga hiko.
Ina pēhia te pēhanga mai i raro, ka piko te wāhanga. Mā tēnei ka roa ake te paparanga graphene kua whakauruhia, ka huri i ōna āhuatanga hiko.
Ngā hanawiti i runga i te whata
I te tuatahi i hangaia e ngā kaipūtaiao he hanawiti "hanawiti" me te paparanga graphene i waenganui i ngā paparanga e rua o te boron nitride. Ko ngā wāhanga e whakaratohia ana me ngā hononga hiko ka pania ki te papa ngohengohe.
Kua hurihia te āhua hikoI te tuatahi i whakamahia e ngā kairangahau ngā tikanga whatu hei whakatikatika i te totoro o te graphene. Kātahi ka whakamahia e rātou ngā tikanga hiko ngā inenga kawe hei ako i te āhua o te whakarerekētanga o te graphene i te pūngao irahiko. Ko ēnei Me mahi ngā ine i te pāmahana -269°C kia kite ai i ngā panonitanga pūngao.
Ngā hoahoa taumata pūngao o te pūrere o tētahi graphene kore-taurite me tētahi graphene kua taurite (kakariki te atarangi) i te pūwāhi utu kore (CNP). "Ko te tawhiti i waenga i ngā karihi ka pā tika ki ngā āhuatanga o ngā āhua hiko i roto i te graphene," te kōrero a Baumgartner.i whakarapopototia ngā hua. "Mēnā he ōrite te totoro, ko te tere me te pūngao irahiko anake ka taea te huri. Ko te huringa oKo te pūngao te pūmanawa tauine i matapaetia e te ariā, ā, kua taea e tātou te whakamatau i tēnei mā roto ingā whakamātautau." E taea ana te whakaaro ko ēnei hua ka arahi ki te whanaketanga o ngā pūoko, ngā momo transistors hou rānei. Hei tāpiri,Ko te graphene, hei pūnaha tauira mō ētahi atu rauemi rua-ahu, kua noho hei kaupapa rangahau nui puta noa i te aongā tau tata nei.
