Makonda a Lithoate Niobate (Ln) Chithunzithunzi

Lithiamu Niobate (Ln) ili ndi mawonekedwe apadera a kyeretse komanso zolimbitsa thupi, monga osagwirizana, zotsatira zoyipa, electro-electro, zotsatira za pyroelectric, ndi zotsatira za Piezelectric. Nthawi yomweyo, ili ndi zabwino zokhudzana ndi zenera la masamba owoneka bwino komanso kukhazikika kwa nthawi yayitali. Makhalidwe awa amapanga ntpumu yofunika ya m'badwo watsopano wa zithunzi. Zida zamisala ndi maptoeclectronic njira, mikhalidwe ya LN imatha kupatsa ntchito zolemera komanso magwiridwe antchito, kulimbikitsa kukula kwa kulumikizana kowoneka, kuphatikiza kwa matoming, komanso minda yamiyala. Komabe, chifukwa cha kuyamwa kofooka ndi kuperewera kwa chinthu cha lifiyamu niobate, kugwiritsa ntchito gawo la lithiate niobate akukumana ndi vuto la kuwoneka bwino. M'zaka zaposachedwa, malipoti m'munda uno umaphatikizapo zophatikizira zomwe zidaphatikizira zithunzi zokongola komanso zojambula za heterojunation.
Chiwonetsero chophatikizira chophatikizidwa ndi lithiamu Niobate nthawi zambiri amayang'ana pa kulumikizana kwa C-Bandi (1525-1565nm). Pankhani ya ntchito, ln makamaka imagwiritsa ntchito mafunde otsogozedwa, pomwe aptoectonic imadalira makamaka silika, iii-v Gulu Lopapatidwa, ndi zida ziwiri. Mu zomanga zotere, kuwala kumafalikira kudzera mu lithiate kuwoneka kosawoneka bwino ndi zotayika zotsika mtengo (monga chithunzi china china) chowonjezera chonyamula magetsi ndikusintha kukhala magetsi pamagetsi. Ubwino ndi wogwirira bandwidth (~ ghz), magetsi otsika oyenda, kukula kochepa, komanso kuphatikizidwa ndi kuphatikiza kép. Komabe, chifukwa cha kulekanitsidwa kwa chipongwe cha lithiate ndi semicotector, ngakhale aliyense amachita ntchito zawo, ln amangochita mbali zowongolera ndi zinthu zina zakunja zomwe sizinagwiritsidwe ntchito bwino. Zipangizo za Semiconductor imangopanga gawo lotembenuka motembenuka kwa potoelectric ndipo alibe kulumikizana wina ndi mnzake, zomwe zimapangitsa kuti azingogwiritsa ntchito pang'ono. Pankhani ya kukhazikitsa mwachindunji, kulumikizidwa kochokera ku gwero lowunikira ku Liobate Niobate Onfoide Onfoadia Kuphatikiza apo, mphamvu yam'madzi kwenikweni ya kuwala kowala ndi semiconductor njira yolumikizira ikuluikulu ku carbibrate, yomwe imachepetsa ntchito yake.
Zachikhalidweojambula zithunziNtchito poyerekeza mapulogalamu nthawi zambiri zimakhazikika pazinthu za semiconductor. Chifukwa chake, ku Liobate Niobate, kuyamwa kwake kotsika komanso kukhazikitsa katundu kumapangitsa kuti zisakomere mosakayikira ndi akatswiri ofufuzawo, ndipo ngakhale panali mfundo yovuta m'munda. Komabe, kukula kwa ukadaulo wachiwerewere m'zaka zaposachedwa kwadzetsa chiyembekezo pakufufuza kwa zithunzi za Liobate Niobode. Zipangizo zina ndi mayamwidwe owala kapena mawonekedwe abwino amatha kuphatikizidwa ndi lithiate Niobate kuti alipire zolakwa zake. Nthawi yomweyo, polandation polarization yoyika pyroelectric ya lithiamu niobate chifukwa chosinthana ndi kutentha kwa ma actoelectronic kupezeka kwa Optoelectronic. Thermal zotsatira zake zimakhala ndi zabwino zanyengo komanso kudziletsa, ndipo zitha kuphatikizidwa komanso zogwiritsidwa ntchito ndi zinthu zina. Kugwiritsa ntchito mogwirizana kwa zotsatira za mafuta ndi zojambulajambula zatsegulira chiwonetsero chatsopano cha zithunzi za lithiate Nioboetor, zomwe zimathandizira zida zophatikiza zabwino zonsezi. Ndikupanga zolakwazo ndikukwaniritsa zophatikiza zambiri, ndi chisangalalo chambiri m'zaka zaposachedwa. Kuphatikiza apo, kugwiritsa ntchito kwa ion kulowetsedwa, bungwe laiviling, ndi chilema cabwinoling ndi chisankho chabwino chothetsa zovuta kupeza lithiamp Niobate Niobate Niobate Niobate Niobate Niobate. Komabe, chifukwa cha zovuta zapamwamba za lithiamu Niobate, mundawu umakumananso ndi zovuta monga kuphatikizidwa kwakukulu, magawo aganizidwe, komanso ntchito yosakwanira, yomwe ili ndi mtengo wofufuzira kwambiri.

Chithunzi 1, kugwiritsa ntchito zoperewera mkati mwa ln bandgap monga nyumba zamagetsi, oyang'anira magetsi amangopangidwa mu gulu lodzaza ndi chidule. Poyerekeza ndi pyroectric ln ma plondoders, omwe nthawi zambiri amangoyankha mwachangu pafupifupi 100Hz, iziLn chithunziili ndi liwiro mwachangu mpaka 10khz. Pakadali pano, mu ntchitoyi, zidawonetsedwa kuti magnesium ion yomwe imapangidwira RN imatha kukwaniritsa zosintha zakunja ndikuyankha mpaka 10kHz. Ntchitoyi imalimbikitsa kafukufuku pa magwiridwe antchito kwambiri ndipoothamanga kwambiri lnPomanga zolimbitsa thupi zokwanira kuphatikizira tchipisi tating'ono.
Mwachidule, gawo lofufuzira lawoonda filimu lithiate Nioboteili ndi tanthauzo lofunikira lasayansi komanso ntchito yothandiza kwambiri. M'tsogolomu, ndikukula kwa ukadaulo ndi kuwona za kafukufuku, woonda wafinya nithium niobate (Ln) zithunzi zimayamba kuphatikizidwa kwambiri. Kuphatikiza njira zosiyanasiyana zophatikizira kuti mukwaniritse bwino kwambiri Mbadwo watsopano wa ntchito za Photosnatic.
