I-Graphene iququzelela umaleko omnye we-carbon atom acwangciswe kwi-hexagonal lagece. Esi sixhobo siguquguquka kakhulu kwaye sinezinto ezintle ze-elektroniki, zisenza ukuba zibe nomtsalane kwizicelo ezininzi-ngakumbi izinto ezenziwa ngamacandelo e-elektroniki.
Abaphandi abakhokelwa nguNjingalwazi abangamaKristu uSchönebemberger ovela kwiSwitzerland kwiziko le-Switzescial School kunye neSebe leFiziksi leDyunivesithi yase-Basel bafunda iIipropati ze-elektroniki zezinto zokufakwa koomatshini bokuzolula.Ukuze benze oku, baqulunqa isikhokelo apho i-atomical ratom diamine ingoluliwe ngendlela elawulwayo ngelixa ilinganisa iipropathi zayo ze-elektroniki.
Xa uxinzelelo lusetyenziswa ukusuka ngezantsi, icandelo liya kugoba. Oku kubangela ukuba umlingane weGraphene weGraphene kwi-Elongate kwaye utshintshe iipropathi zayo zombane.
Isandwich kwishalofini
Izazinzulu zaza zavelisa isandwich ye-sandwich enomaleko wegraphene phakathi kweendawo ezimbini ze-boron nitride. Amacandelo anikezwe ngonxibelelwano lombane asetyenziswa kwindawo eguquguqukayo.
Itshintshiwe ilizwe le-elektronikiAbaphandi baqala ukusebenzisa iindlela zokwenza izinto zokulinganisa ukolula igraphene. Basebenzise umbane Imilinganiselo yezothutho yokufunda indlela idigrine yedigok yatshintsha ngayo amandla e-elektroni. Ezi Imilinganiselo kufuneka yenziwe kwi-269 ° C ukubona utshintsho lwamandla.
Imizobo yeNqanaba lemifanekiso yeGraine engafundekiyo kunye ne-B i-Bled (i-Green Shophene) yeGraine kwindawo engathathi hlangothi (CNP). "Umgama phakathi kwe-nuclei ngokuthe ngqo ichaphazela iimpawu ze-elektroniki e-elektroniki," baumgartnerShwankathela iziphumo. "Ukuba ukolula kuyinto efanayo, kuphela isantya se-elektroni kuphela kwaye amandla anokutshintsha. Utshintsho ngaphakathiAmandla ngokuyimfuneko okunokubakho kwinqanaba eliqikelelweyo kwangaphambili yithiyori, kwaye ngoku siye sakwazi ukubonisa okuiimvavanyo. " Kuyacingelwa ukuba ezi ziphumo ziya kukhokelela kuphuhliso lweenzwa okanye iintlobo ezintsha zokuzisela. Ukwengeza,I-Graphene, njengenkqubo yemodeli yezinye izinto ezinemilinganiselo emibini, iye yaba sisihloko esibalulekileyo sophando kwihlabathi liphelaIminyaka yakutshanje.
