Njengoba ama-transistors eqhubeka enziwa ama-miniaturized, imigudu aqhuba ngawo i-current iya ngokuya iba mincane futhi iba mincane, okudinga ukuqhubeka nokusetshenziswa kwezinto ezihamba phambili zama-electron. Izinto ezinezinhlangothi ezimbili ezifana ne-molybdenum disulfide zilungele ukuhamba kwe-electron ephezulu, kodwa uma kuxhunywe izintambo zensimbi, kwakheka umgoqo we-Schottky endaweni yokuxhumana, into evimbela ukugeleza kweshaja.
NgoMeyi 2021, ithimba labacwaningi elihlangene eliholwa yi-Massachusetts Institute of Technology futhi labamba iqhaza yi-TSMC nabanye baqinisekisa ukuthi ukusetshenziswa kwe-semi-metal bismuth kuhlanganiswe nokuhlelwa okufanele phakathi kwezinto ezimbili kunganciphisa ukumelana nokuxhumana phakathi kocingo nocingo. , ngaleyo ndlela kuqedwe le nkinga. , esiza ukufeza izinselele ezinzima zama-semiconductors angaphansi kwe-nanometer engu-1.
Ithimba le-MIT lithole ukuthi ukuhlanganisa ama-electrode ne-semimetal bismuth endaweni enezinhlangothi ezimbili kunganciphisa kakhulu ukumelana nokwandisa ukudluliswa kwamanje. Umnyango wocwaningo lwezobuchwepheshe we-TSMC wabe usuthuthukisa inqubo yokubeka i-bismuth. Ekugcineni, ithimba Lenyuvesi Kazwelonke YaseTaiwan lasebenzisa "uhlelo lwe-helium ion beam lithography" ukuze linciphise ngempumelelo isiteshi sengxenye sibe usayizi we-nanometer.
Ngemuva kokusebenzisa i-bismuth njengesakhiwo esiyinhloko se-electrode yokuxhumana, ukusebenza kwe-transistor yezinto ezibonakalayo ezinezinhlangothi ezimbili akufani nje naleyo yama-semiconductors asekelwe ku-silicon, kodwa futhi kuyahambisana nobuchwepheshe benqubo yamanje obusekelwe ku-silicon, obuzosiza yeqa imikhawulo yoMthetho kaMoore ngokuzayo. Lokhu kuphumelela kwezobuchwepheshe kuzoxazulula inkinga enkulu yama-semiconductors anezinhlangothi ezimbili ezingena embonini futhi kuyingqopha-mlando ebalulekile yamasekethe ahlanganisiwe ukuthi aqhubeke nokuthuthuka enkathini ye-post-Moore.
Ngaphezu kwalokho, ukusebenzisa isayensi yezinto zekhompyutha ukuthuthukisa ama-algorithms amasha ukuze kusheshiswe ukutholwa kwezinto ezintsha eziningi nakho kuyindawo eshisayo ekuthuthukisweni kwamanje kwezinto zokwakha. Isibonelo, ngoJanuwari 2021, I-Ames Laboratory yoMnyango Wezamandla wase-US yashicilela isihloko esithi "Cuckoo Search" kujenali ethi "Natural Computing Science". Le algorithm entsha ingasesha ama-alloys aphezulu. isikhathi kusuka emavikini kuya kumasekhondi. I-algorithm yokufunda yomshini eyakhiwe yi-Sandia National Laboratory e-United States ishesha ngokuphindwe izikhathi ezingu-40,000 kunezindlela ezijwayelekile, ifinyeza umjikelezo wokuklama wobuchwepheshe bezinto ezibonakalayo cishe unyaka. Ngo-April 2021, abacwaningi eNyuvesi yase-Liverpool e-United Kingdom bakha irobhothi elingaklama ngokuzimela imizila yokusabela kwamakhemikhali ezinsukwini ezingu-8, liqedele ukuhlola okungu-688, futhi lithole i-catalyst ephumelelayo yokuthuthukisa ukusebenza kwe-photocatalytic yama-polymer.
Kuthatha izinyanga ukukwenza mathupha. I-Osaka University, eJapane, isebenzisa izinto zeseli ye-photovoltaic engu-1,200 njengesizindalwazi sokuqeqesha, yafunda ubudlelwano phakathi kwesakhiwo sezinto ze-polymer kanye nokungeniswa kwe-photoelectric ngokusebenzisa ama-algorithms okufunda ngomshini, futhi yahlola ngempumelelo ukwakheka kwezinhlanganisela ezinokusetshenziswa okungenzeka kungakapheli iminithi elingu-1. Izindlela zendabuko zidinga iminyaka emi-5 kuye kweyisi-6.
