Ke hoʻomau nei ka liʻiliʻi ʻana o nā transistors, ʻoi aku ka liʻiliʻi o nā kahawai e holo ai lākou i kēia manawa, e koi ana i ka hoʻohana mau ʻana i nā mea uila uila kiʻekiʻe. ʻO nā mea ʻelua-dimensional e like me ka molybdenum disulfide he mea kūpono ia no ka neʻe electron kiʻekiʻe, akā ke hoʻopili ʻia me nā uwea metala, ua hoʻokumu ʻia kahi pale Schottky ma ka pilina pili, kahi mea e pale ai i ke kahe o ka uku.
I Mei 2021, kahi hui noiʻi hui i alakaʻi ʻia e ka Massachusetts Institute of Technology a ua komo ʻia e TSMC a me nā mea ʻē aʻe i hōʻoia i ka hoʻohana ʻana i ka bismuth semi-metal i hui pū ʻia me ka hoʻonohonoho kūpono ma waena o nā mea ʻelua e hiki ke hōʻemi i ke kūpaʻa pili ma waena o ka uea a me ka hāmeʻa. , pela e hoopau ai i keia pilikia. , kōkua i ka hoʻokō ʻana i nā pilikia weliweli o nā semiconductor ma lalo o 1 nanometer.
Ua ʻike ka hui MIT ʻo ka hoʻohui ʻana i nā electrodes me ka bismuth semimetal ma kahi mea ʻelua-dimensional hiki ke hōʻemi nui i ke kū kūʻē a hoʻonui i ka hoʻouna ʻana i kēia manawa. A laila ua hoʻopaneʻe ke keʻena noiʻi ʻenehana o TSMC i ke kaʻina hana deposition bismuth. ʻO ka hope loa, ua hoʻohana ka hui ʻo National Taiwan University i kahi "helium ion beam lithography system" no ka hoʻohaʻahaʻa pono ʻana i ke kahawai ʻāpana i ka nui nanometer.
Ma hope o ka hoʻohana ʻana i ka bismuth ma ke ʻano he kumu nui o ka electrode contact, ʻaʻole i hoʻohālikelike ʻia ka hana o ka transistor mea ʻelua-dimensional me ka semiconductors-based silicon, akā pili pū kekahi me ka ʻenehana kaʻina hana silicon-based o kēia manawa, e kōkua i ka hoʻohana ʻana i ka bismuth. e uhaki i na palena o ke Kanawai o Moore i keia mua aku. E hoʻopau kēia ʻenehana ʻenehana i ka pilikia nui o nā semiconductor ʻelua-dimensional e komo ana i ka ʻoihana a he mea koʻikoʻi koʻikoʻi no nā kaapuni hoʻohui e hoʻomau i ka holomua i ka wā post-Moore.
Eia kekahi, ʻo ka hoʻohana ʻana i ka ʻepekema waiwai helu e hoʻomohala i nā algorithms hou e hoʻolalelale i ka loaʻa ʻana o nā mea hou aʻe he wahi wela hoʻi i ka hoʻomohala ʻana o nā mea. No ka laʻana, ma Ianuali 2021, ua paʻi ka Ames Laboratory o ka US Department of Energy i kahi ʻatikala ma ka "Cuckoo Search" algorithm ma ka puke pai "Natural Computing Science". Hiki i kēia algorithm hou ke ʻimi i nā alloys high-entropy. manawa mai nā pule a kekona. ʻO ka algorithm aʻo mīkini i hoʻomohala ʻia e Sandia National Laboratory ma ʻAmelika Hui Pū ʻIa he 40,000 mau manawa ʻoi aku ka wikiwiki ma mua o nā hana maʻamau, e hoʻopōkole ana i ka pōʻai hoʻolālā o nā ʻenehana waiwai ma kahi kokoke i hoʻokahi makahiki. I ʻApelila 2021, ua hoʻomohala ka poʻe noiʻi ma ke Kulanui o Liverpool ma United Kingdom i kahi robot e hiki ke hoʻolālā kūʻokoʻa i nā ala hoʻonā kemika i loko o nā lā 8, hoʻopau i nā hoʻokolohua 688, a loaʻa i kahi catalyst maikaʻi e hoʻomaikaʻi i ka hana photocatalytic o nā polymers.
He mau mahina e hana ai me ka lima. Osaka University, Iapana, me ka hoʻohana 'ana i 1,200 photovoltaic cell materials as a training database, study the relationship between the structure of polymer material and photoelectric induction through machine learning algorithms, and successful screened out the structure of compounds with potential applications within 1 minute. Pono nā ʻano kuʻuna 5 a 6 mau makahiki.
