Raws li cov transistors txuas ntxiv mus rau miniaturized, cov channel uas lawv ua tam sim no tau txais kev nqaim thiab nqaim, yuav tsum tau siv txuas ntxiv ntawm cov khoom siv hluav taws xob siab. Cov khoom siv ob sab xws li molybdenum disulfide yog qhov zoo tshaj plaws rau kev txav hluav taws xob siab, tab sis thaum sib cuam tshuam nrog cov xov hlau hlau, Schottky teeb meem yog tsim los ntawm kev sib cuag, qhov tshwm sim uas cuam tshuam cov nqi ntws.
Thaum lub Tsib Hlis 2021, pab pawg tshawb fawb sib koom ua ke coj los ntawm Massachusetts Institute of Technology thiab koom nrog TSMC thiab lwm tus tau lees paub tias kev siv ib nrab hlau bismuth ua ke nrog kev npaj kom zoo ntawm ob cov ntaub ntawv tuaj yeem txo qhov kev sib cuag ntawm cov hlau thiab cov cuab yeej. , yog li tshem tawm qhov teeb meem no. , pab kom ua tiav cov kev sib tw daunting ntawm semiconductors hauv qab 1 nanometer.
Pab pawg MIT pom tias kev sib txuas cov electrodes nrog semimetal bismuth ntawm cov khoom siv ob sab tuaj yeem txo qhov tsis kam thiab nce kev sib kis tam sim no. TSMC's technical research department ces optimized bismuth deposition process. Thaum kawg, pab pawg National Taiwan University tau siv "helium ion beam lithography system" los ua kom tiav cov khoom sib txuas rau nanometer loj.
Tom qab siv bismuth ua tus qauv tseem ceeb ntawm kev sib cuag electrode, qhov kev ua tau zoo ntawm ob sab ntawm cov khoom siv transistor tsis yog tsuas yog piv rau cov khoom siv silicon-based semiconductors, tab sis kuj tau sib xws nrog cov txheej txheem tseem ceeb ntawm silicon-based technology, uas yuav pab tau. rhuav tshem cov kev txwv ntawm Moore Txoj Cai yav tom ntej. Qhov kev siv thev naus laus zis no yuav daws tau qhov teeb meem tseem ceeb ntawm ob-seem semiconductors nkag mus rau hauv kev lag luam thiab yog lub hauv paus tseem ceeb rau kev sib koom ua ke kom txuas ntxiv mus rau lub sijhawm tom qab Moore.
Tsis tas li ntawd, kev siv cov ntaub ntawv suav nrog kev tshawb fawb los tsim cov algorithms tshiab txhawm rau txhawm rau tshawb pom cov ntaub ntawv tshiab ntxiv kuj yog qhov chaw kub kub hauv kev txhim kho cov ntaub ntawv tam sim no. Piv txwv li, thaum Lub Ib Hlis 2021, Ames Laboratory ntawm US Department of Energy tau luam tawm ib tsab xov xwm ntawm "Cuckoo Search" algorithm hauv phau ntawv journal "Natural Computing Science". Qhov tshiab algorithm no tuaj yeem tshawb nrhiav high-entropy alloys. lub sij hawm los ntawm lub lis piam mus rau vib nas this. Lub tshuab kev kawm algorithm tsim los ntawm Sandia National Laboratory nyob rau hauv lub tebchaws United States yog 40,000 lub sij hawm sai dua li cov kev zoo tib yam, shortening lub voj voog tsim ntawm cov ntaub ntawv technology los ntawm ze li ntawm ib xyoos. Thaum lub Plaub Hlis 2021, cov kws tshawb fawb ntawm University of Liverpool hauv tebchaws United Kingdom tau tsim cov neeg hlau uas tuaj yeem tsim cov tshuaj lom neeg ntawm nws tus kheej hauv 8 hnub, ua tiav 688 qhov kev sim, thiab nrhiav cov khoom siv tau zoo los txhim kho cov photocatalytic kev ua haujlwm ntawm polymers.
Nws yuav siv sij hawm ntau lub hlis los ua nws tus kheej. Osaka University, Nyiv, siv 1,200 photovoltaic cell cov ntaub ntawv raws li kev cob qhia database, kawm txog kev sib raug zoo ntawm cov qauv ntawm cov ntaub ntawv polymer thiab photoelectric induction los ntawm kev kawm tshuab algorithms, thiab ua tau zoo soj ntsuam cov qauv ntawm cov tebchaw nrog tej yam kev siv nyob rau hauv 1 feeb. Cov txheej txheem ib txwm siv 5 mus rau 6 xyoo.
