Njengoko i-transistors iqhubeka i-miniaturized, imigudu abaqhuba ngayo i-current iya iyancipha kwaye iyancipha, ifuna ukusetyenziswa okuqhubekayo kwezinto ezihamba phambili ze-electron.Izinto ezimbini-dimensional ezifana ne-molybdenum disulfide zilungele ukuhamba kwe-electron ephezulu, kodwa xa zidibene neengcingo zetsimbi, umqobo we-Schottky wenziwa kwi-interface yoqhagamshelwano, into evimbela ukuhamba kwentlawulo.
NgoMeyi ka-2021, iqela lophando elidibeneyo elikhokelwa yi-Massachusetts Institute of Technology kwaye lithathe inxaxheba yi-TSMC kunye nabanye baqinisekisa ukuba ukusetyenziswa kwe-bismuth ye-semi-metal edityaniswe nolungiselelo olufanelekileyo phakathi kwezinto ezimbini kunokunciphisa ukuchasana koqhagamshelwano phakathi kocingo kunye nesixhobo. , ngaloo ndlela kupheliswa le ngxaki., ukuncedisa ukufezekisa imingeni enzima yee-semiconductors ngaphantsi kwe-nanometer ye-1.
Iqela le-MIT lifumene ukuba ukudibanisa i-electrodes kunye ne-bismuth ye-semimetal kwi-two-dimensional material inokunciphisa kakhulu ukuchasana kunye nokwandisa ukuhanjiswa kwangoku.Isebe lophando lobuchwephesha le-TSMC emva koko laphucula inkqubo yokubekwa kwe-bismuth.Ekugqibeleni, iqela leYunivesithi yaseTaiwan yeSizwe yasebenzisa "i-helium ion beam lithography system" ukunciphisa ngempumelelo ishaneli yecandelo kwisayizi ye-nanometer.
Emva kokusebenzisa i-bismuth njengesakhiwo esibalulekileyo se-electrode yoqhagamshelwano, ukusebenza kwe-transistor yezinto ezimbini-dimensional ayifani kuphela ne-silicon-based semiconductors, kodwa iyahambelana neteknoloji yenkqubo ye-silicon-based yangoku, eya kunceda baphule imida yoMthetho kaMoore kwixesha elizayo.Le nkqubela phambili yezobuchwepheshe iya kusombulula ingxaki ephambili ye-semiconductors ene-dimensional-dimensional engena kwishishini kwaye ibaluleke kakhulu kwiisekethe ezidibeneyo ukuze ziqhubeke nokuqhubela phambili kwixesha le-post-Moore.
Ukongeza, ukusebenzisa izixhobo zokubala zesayensi ukuphuhlisa i-algorithms entsha ukukhawulezisa ukufunyanwa kwezixhobo ezitsha kukwayindawo eshushu kuphuhliso lwangoku lwemathiriyeli.Ngokomzekelo, ngoJanuwari 2021, i-Ames Laboratory yeSebe lezaMandla lase-US yapapasha inqaku kwi-algorithm ethi "Cuckoo Search" kwiphephancwadi elithi "Natural Computing Science".Le algorithm entsha inokukhangela i-alloys ephezulu ye-entropy.ixesha ukusuka kwiiveki ukuya kwimizuzwana.I-algorithm yokufunda ngomatshini ephuhliswe yiSandia National Laboratory e-United States i-40,000 amaxesha ngokukhawuleza kuneendlela eziqhelekileyo, inciphisa umjikelo woyilo lwethekhnoloji yemathiriyeli phantse unyaka.Ngo-Epreli ka-2021, abaphandi kwiYunivesithi yaseLiverpool e-United Kingdom baphuhlise irobhothi enokuzimela ngokuzimeleyo iindlela zokusabela kweekhemikhali phakathi kweentsuku ezisi-8, igqibe imifuniselo engama-688, kwaye ifumane i-catalyst esebenzayo yokuphucula ukusebenza kwe-photocatalytic yeepolymers.
Kuthatha iinyanga ukwenza oko ngesandla.IYunivesithi yase-Osaka, eJapan, isebenzisa izixhobo ze-cell photovoltaic ze-1,200 njengesiseko sedatha yoqeqesho, yafunda ubudlelwane phakathi kwesakhiwo sezinto ze-polymer kunye nokungeniswa kwe-photoelectric ngokusebenzisa i-algorithms yokufunda ngomatshini, kwaye ihlolisise ngempumelelo isakhiwo se-compounds kunye nezicelo ezinokubakho ngaphakathi kwe-1 iminithi.Iindlela zemveli zifuna iminyaka emi-5 ukuya kwe-6.
