Abaningi bebekhuluma ezinyangeni ezisanda kwedlula ngobukhulu bamathuba ento efana nayo i-graphene. Kunjalo-ke okwamanje, kubonakala sengathi yonke into, kusuka kumabhethri kuya ezingutsheni, ingcono uma, ngesikhathi esithile ekwakhiweni kwayo, i-graphene isetshenziselwe ukwenziwa kwayo.
Ngaphandle kwakho konke lokhu, yize namhlanje kunabacwaningi abaningi abasebenza ngezinketho ezintsha zalolu daba, iphrojekthi lapho kutshalwa khona imali eningi, iqiniso ukuthi zonke lezi zindaba ezithokozisayo zibonakala ngathi azisoze zafika emakethe. Ngalesi sikhathi ngifuna sikhulume ngephrojekthi entsha, efanayo lapho, ngenxa yosizo lwe-graphene, iqembu labaphenyi likwazile ukwenza ukukhanya kufinyelela esikhaleni esincane kakhulu kunobude bayo, okuthile okungafanele kwenzeke.
Ngenxa ye-graphene, iqembu labacwaningi likwazile ukuletha ukukhanya ezindaweni ezincane kunobude bayo
Njengoba ephawule ezitatimendeni zakhe UFrank Koppens, umphenyi oyinhloko wale phrojekthi nomsebenzi we Isikhungo se-Photonic Sciences yaseSpain:
UGraphene uyaqhubeka nokusimangaza: akekho owacabanga ukuthi ukukhawulela ukukhanya kumkhawulo we-athomu kungenzeka. Izovula isethi entsha yezinhlelo zokusebenza, njengokuxhumana kokukhanya nezinzwa esikalini esingaphansi kwe-nanometer eyodwa.
Njengoba ubona, kucatshangelwa izitatimende ezenziwe nguFrank Koppens, ukuthola ukukhanya ezindaweni ezincane ezinjalo kuvula okusha inkambu igcwele amathuba, ikakhulukazi emhlabeni we-elekthronikhi, izinzwa namadivayisi we-imaging wesikhathi esizayo. Ngokuqondile, lokhu okusha, noma okungenani indlela okuchazwe ngayo, kungaholela ekubeni sakhe ama-chips amadivayisi ethu amancane kakhulu kunalawo asetshenziswa namuhla.
Ukusetshenziswa kwe-graphene kusivumela ukuqondisa ukukhanya ezindaweni ezincane njenge-athomu
Ukungena emininingwaneni ethe xaxa, ngikutshele lokho ngokuvamile ukukhanya akukwazi ukugxila ephuzwini elincane kunebude bayo, umgoqo owaziwa ngegama le- umkhawulo wokusuka. Kuze kube manje, abacwaningi abaningi bebelokhu besebenzela ukunqoba lo mkhawulo, yize imikhawulo ebekwe yiwo isho ukuthi kumele kusetshenziswe amandla amaningi kakhulu.
Kulesi senzakalo esithile, abacwaningi abaphethe ukuthuthukiswa kwale phrojekthi basebenzise izinto ezinokwakheka okubili, ezaziwa ngokuthi ama-heterostructures, ukuze bakhe idivaysi entsha ye-nano-optical lapho bengeze khona i-graphene monolayer ukwenza sengathi semi-metallic. Ngenxa yalokhu ukukhanya kungaqondiswa ngendlela yama-plasmonAma-oscillations e-electron asebenzisana ngokuqinile nokukhanya futhi angasetshenziswa ukukuqondisa.
Ngamazwi ka UDavid alcaraz, elinye lamalungu ethimba locwaningo elisebenza ekwakhiweni kwale phrojekthi:
Ekuqaleni besifuna indlela entsha yokuthakazelisa ama-plasmon we-graphene. Esikhundleni salokho, sithole ukuthi ukuvalelwa kunamandla kunakuqala futhi ukulahlekelwa okungeziwe bekukuncane. Ngakho-ke sinqume ukuya kumkhawulo we-athomu ngemiphumela emangazayo.
Kumele sisebenzele ukunciphisa ezinye izingxenye ze-chip ukuze sizuze amadivayisi amancane
Ngaphandle kokungabaza, ukukwazi ukulawula ukukhanya esiteshini esingaphansi kobukhulu be-nanometer kuyindlela enhle ezovumela abantu dala amadivayisi amancane kakhulu. Okubi kulokhu ukuthi ukushintshwa okuncane kakhulu kwe-optical, izinzwa nemitshina nakho kuzodingeka kuthuthukiswe ukufeza lokhu.
Umsebenzi wokwakha ama-transistor asuselwa ekukhanyeni usevele uyaqhubeka. Uma indlela yokukhiqiza isitholakala, kuzoba ithuba labakhiqizi, okumele bayisebenzise ukuze bayizuze phakamisa ama-transistor amaningi esikhaleni esifanayo, ngaleyo ndlela kuthuthukiswe ukusebenza kwama-chips wamanje, noma lilingana nenani elifanayo lama-transistor atholakele ku-chip namuhla ukunciphisa ubukhulu ngosayizi kuwo
