SiliconphotodetectorSau cov ntaub ntawv: sab nraud Quantum tau nce mus txog 132%
Raws li cov ntaub ntawv tshaj tawm xov xwm, cov kws tshawb nrhiav ntawm Aalto University tau tsim kho Optoelectronic ntaus ntawv nrog Qua Qog sab nrauv txog li 132%. Qhov no tsis zoo li tau ua tiav los ntawm kev siv nanostructured dub silicon, uas tuaj yeem yog qhov sib tawg loj rau cov hlwb hnub ci thiab lwm yamphotodetectorsCov. Yog tias cov khoom siv hypotetical muaj cov qoj ib ce sab nraud ntawm 100 feem pua, uas txhais tau tias txhua lub photon uas nws ua rau hluav taws xob, uas tau sau raws li hluav taws xob los ntawm kev siv hluav taws xob.
Thiab cov cuab yeej tshiab no tsis yog ua tiav 100 feem pua ua tau zoo, tab sis ntau tshaj 100 feem pua. 132% txhais tau tias yog qhov nruab nrab ntawm 1.32 hluav taws xob ib tus photon. Nws siv cov khoom cua dub ua cov khoom siv nquag thiab muaj lub khob hliav qab thiab contacar nanostructure teeb uas tuaj yeem nqus cov teeb tsa.
Qhov tseeb tiag koj tsis tuaj yeem tsim 0.32 cov hluav taws xob ntxiv tawm ntawm cov cua nyias nyias, tom qab lub zog uas tsis tuaj yeem tsim tawm ntawm cov pa roj nyias nyias, yog li qhov twg ua cov hluav taws xob ntxiv los ntawm?
Txhua yam nws tau los rau tus ua haujlwm dav dav ntawm photovoltaic cov ntaub ntawv. Thaum lub photon ntawm qhov xwm txheej lub teeb ua cov tshuaj nquag, feem ntau silicon, nws khob hluav taws xob tawm ntawm ib qho ntawm atoms. Tab sis nyob rau hauv qee kis, lub zog hluav taws xob photo tuaj yeem khob tawm ob lub tshuab hluav taws xob yam tsis muaj kev cai ntawm lub cev.
Muaj tsis muaj kev tsis ntseeg tias txoj kev tshwm sim no tuaj yeem pab tau zoo heev hauv kev txhim kho cov qauv tsim ntawm cov yeeb yaj kiab hlwb. Hauv ntau Optoelectronic cov ntaub ntawv, ua tau zoo yog ploj nyob rau hauv ntau cov kev, suav nrog thaum photombine nrog rau "qhov" sab laug hauv Circuit Court ua ntej yuav sau los ntawm Circuit Court.
Tab sis Aalto cov pab pawg hais tias lawv tau tshem cov teeb meem ntawd. Silicon nqus tau ntau tshaj li lwm yam ntaub ntawv, thiab cov tapered thiab colaper nanostron recommination ntawm cov khoom saum npoo.
Zuag qhia tag nrho, cov kev nce qib no tau qhib cov khoom sab nraud ntawm cov cuab yeej kom ncav cuag 130%. Pab pawg cov txiaj ntsig tau hais txog ntawm Lub Tebchaws Yelemees ntawm Tebchaws Yelemees Lub Tebchaws Metrology Lub Tebchaws Motrology, PTB (German Federnal Institute ntawm Physics).
Raws li cov kws tshawb nrhiav, cov ntaub ntawv no yuav txhim kho kev ua tau zoo ntawm cov ntaub ntawv, suav nrog lub teeb tsa hnub ci thiab lwm yam tshiab tau siv kev lag luam.
