I-Graphene iqukethe ungqimba olulodwa lwama-athomu e-carbon ahlelwe ethangeni le-hexagonal. Lokhu okuguquguqukayo kuvumelana nezimo kakhulu futhi kunezindawo ezinhle kakhulu ze-elekthronikhi, okwenza kukhange ngezicelo eziningi - ikakhulukazi izingxenye ze-elekthronikhi.
Abaphenyi baholwa nguProfessor Christian Schönenberger kusuka eSwitzerland Institute of Nanoscience kanye noMnyango we-physics we-University of Basel bafundela indlela yokusebenzisaIzakhiwo ze-elekthronikhi zezinto zokwelula zokwelula.Ukuze wenze lokhu, bahlakulela uhlaka lapho ungqimba lwe-graphic macinotha oluncane lungalulwa ngendlela elawulwayo ngenkathi ulinganisa izakhiwo zalo ze-elekthronikhi.

Lapho ingcindezi isetshenziswa kusuka ngezansi, ingxenye izogoba. Lokhu kudala ukuthi i-graphe ene-graphe ene-eshukunwe ikhulise futhi iguqule izakhiwo zayo zikagesi.

Amasemishi eshalofini

Ososayensi baqala ukukhiqiza isamishi "se-sandwich" ephethe ungqimba lwe-graphe yehlela phakathi kwezendlalelo ezimbili zeBoron Nitride. Izakhi ezihlinzekwe ngoxhumana nabo kagesi zisetshenziswa ku-substrate eguquguqukayo.

Abaphenyi babe sebesebenzisa i-wedge ukufaka ingcindezi maphakathi nesangweji kusuka ngezansi. "Siyisebenzisela ukugoba izakhi ngendlela elawulwayo futhi yandise lonke u-graphene ungqimba," kuchaze umlobi wokuqala uDkt Lujun wang.
"I-graphene yelulekayo sisivumela ukuthi sishintshe ibanga phakathi kwama-athomu e-carbon, ngaleyo ndlela siguqule amandla abo okubopha," kungezwa umcwaningi wokuhlola uDkt Andreas Baumgartner.
Ishintshe isimo se-elektronikiAbaphenyi baqale basebenzise izindlela ze-Optical ukukala ukwelula kwe-graphene. Bese besebenzisa ugesi  Izilinganiso zokuThutha ukutadisha ukuthi i-graphiction ishintsha kanjani amandla e-elektroni. Lezi  Izilinganiso zidinga ukwenziwa ku-269 ° C ukubona izinguquko zamandla.

Imidwebo yeleveli yamandla edivaysi ye-graphe ye-untrained futhi b eqinile (eluhlaza okwesibhakabhaka) graphene endaweni yokungathathi hlangothi (CNP).  "Ibanga phakathi kwe-nuclei lithinta ngqo izici zezifunda ze-elekthronikhi kwa-Grapheene," Baumgartnerwafingqa imiphumela. "Uma ukwelula umfaniswano, ijubane le-elektroni kuphela namandla angashintsha. Ushintsho ngaphakathiEnergy empeleni i-scalar ingahle ikhuliswe ngethiyori, futhi manje sesikwazile ukufakazela lokhuizivivinyo. "  Kucatshangelwa ukuthi le miphumela izoholela ekuthuthukisweni kwezinzwa noma izinhlobo ezintsha ze-transtors. Ngaphezu kwalokho,I-Graphene, njengohlelo lwemodeli yezinye izinto ezinezici ezimbili, seluphenduke isihloko esibalulekile sokucwaninga emhlabeni jikelele phakathiiminyaka yamuva.
