Nyias thiab muag cov ntaub ntawv tshiab semiconductor tuaj yeem siv los ua cov micro thiabNano Optoelectronic li
Roperties, thickness ntawm tsuas yog ob peb nanometers, kev tsim kho tshiab ntawm lub tsev kawm ntawv tau npaj siab ua haujlwm ntawm lub tsev kawm ntawv , thiab dhau los ntawm nws kom ua tiav txoj cai ntawm kho qhov muag ntawm ob-seem transition hlau cov ntaub ntawv, uas muab lub tswv yim tshiab rau kev tsim khoom ntawm hnub ci Hlwb thiabphotodetectorsCov. Cov txiaj ntsig tau tshaj tawm nyob rau hauv qhov teeb meem kawg ntawm cov neeg Asmeskas cov ntaub ntawv qib siab siab tshaj plaws.
"Ultra-nyias Las Iodide Nanosheets Peb tau npaj rau thawj zaug, lub sijhawm ua muaj roj av ob lub ntsej muag ', uas yog cov khoom siv ultra " Lub Hnub Yan, tus sau thawj daim ntawv thiab tus kws kho mob uas yuav tsum tau ua ke, hais tias lawv tau siv cov kev daws teeb meem yooj yim, nrawm thiab muaj peev xwm ntsib tus xav tau ntawm loj-cheeb tsam thiab cov khoom muaj txiaj ntsig zoo khoom. Cov synthesized Lead Nodide Nanosheets muaj cov duab peb teev lossis cov duab hexagonal, qhov loj me ntawm 6 microns, du thaj chaw thiab zoo saib.
Cov kws tshawb nrhiav ua ke no cov hmoov av ultra nrog ob-seem tsim qauv, thiab tau tsim ntau hom kev hloov pauv ntawm cov kev sib txawv, yog li cov hmoov txhuas sib txawv, yog cov hmoov txhuas tuaj yeem muaj cov teebmeem sib txawv Ntawm qhov kev ua tau zoo ntawm qhov sib txawv ntawm ob-seem hloov pauv hlau sulfides. Tus qauv hlua khi no yuav ua tau zoo txoj kev luminous ua haujlwm, uas yog qhov ua tau zoo rau cov khoom siv hluav taws xob thiab cov teeb pom kev zoo, thiab tuaj yeem siv rau hauv daim duab ntawm photodetectors thiabPhotovoltaic li.
Qhov kev ua tiav no tau qhia txog kev cai ntawm kho qhov muag ntawm ob-seem transition hlau hlau sulfide cov ntaub ntawv los ntawm ultra-nyias ua iodide. Piv nrog cov khoom siv Optoelectronic raws li ntawm cov khoom uas cov khoom ua si silicon, cov txiaj ntsig no muaj cov yam ntxwv ntawm kev hloov pauv, micro thiab nano. Yog li ntawd, nws tuaj yeem siv rau kev npaj hloov tau thiab ua keOptoelectronic liCov. Nws muaj cov ntawv thov dav dav hauv kev sib xyaw Micro thiab Nano Optoelectronic cuab yeej, thiab muab lub tswv yim tshiab rau kev tsim cov khoom ci ntsa iab, photodetectors thiab lwm yam.
