Pepa keleawe no Graphene

He mea hou ʻo Graphene kahi i hoʻopaʻa paʻa ʻia ai nā ʻātoma kalapona i hoʻopili ʻia e ka sp² hybridization i loko o kahi papa hoʻokahi o ka honeycomb lattice ʻelua-dimensional. Me nā waiwai optical, uila, a me ka mechanical, graphene paʻa i ka ʻōlelo hoʻohiki koʻikoʻi no nā noi i ka ʻepekema waiwai, micro a me nano processing, ikehu, biomedicine, a me ka lawe ʻana i ka lāʻau lapaʻau, a ua manaʻo ʻia he mea kipi o ka wā e hiki mai ana. ʻO ka hoʻoheheʻe ʻana i ka mahu (CVD) kekahi o nā ʻano hana maʻamau no ka hana ʻana o ka graphene ākea nui. ʻO kāna kumu nui ka loaʻa ʻana o ka graphene ma ka waiho ʻana iā ia ma ka ʻili o kahi metala ma ke ʻano he substrate a me ka catalyst, a me ka hāʻawi ʻana i kahi nui o ke kumu kalapona precursor a me ke kinoea hydrogen i loko o kahi kaiapuni kiʻekiʻe, e launa pū me kekahi. ʻO ka pahu keleawe no ka graphene i hana ʻia e CIVEN METAL nā hiʻohiʻona o ka maʻemaʻe kiʻekiʻe, ke kūpaʻa maikaʻi, ka wafer like ʻole a me ka papa pālahalaha, kahi mea substrate kūpono i ka hana CVD.
