Ib pab neeg tshawb fawb los ntawm Helmholtz-Zentrum Berlin (HZB) thiab Humboldt-Universität zu Berlin tau ua tiav thawj zaug hauv kev tsim cov duab hluav taws xob diodes (LEDs) los ntawm cov khoom siv hluav taws xob perovskite semiconductor siv inkjet luam ntawv. Qhov no qhib lub qhov rooj rau daim ntawv thov dav ntawm cov ntaub ntawv hauv kev tsim tawm ntau yam sib txawv hauv cov khoom siv hluav taws xob. Cov kws tshawb fawb ua tiav kev ua tiav nrog kev pab ntawm kev dag:" inoculating" (los yog yub) saum npoo nrog cov muaju.
Microelectronics siv ntau cov ntaub ntawv ua haujlwm uas nws cov khoom ua rau lawv haum rau cov ntawv thov tshwj xeeb. Piv txwv li, transistors thiab cov ntaub ntawv khaws cov khoom siv yog tsim los ntawm silicon, thiab feem ntau photovoltaic hlwb siv los tsim hluav taws xob los ntawm tshav ntuj kuj tseem ua tam sim no ntawm cov khoom siv hluav taws xob no. Hauv kev sib piv, cov sib txuas ua ke (semiconductors) xws li gallium nitride siv los ua lub teeb nyob hauv optoelectronic cov ntsiab lus xws li lub teeb ci hluav taws xob diodes (LEDs). Cov txheej txheem tsim tawm kuj tseem txawv rau ntau cov chav kawm ntawm cov ntaub ntawv.
Transcending cov ntaub ntawv thiab cov kev tshawb
Hybrid perovskite cov ntaub ntawv cog lus yooj yim - los ntawm kev npaj cov organic thiab inorganic Cheebtsam ntawm cov khoom siv hluav taws xob semiconducting siv rau hauv cov qauv tshwj xeeb." Lawv tuaj yeem siv los tsim txhua yam ntawm microelectronic los ntawm kev hloov kho lawv cov kev sib xyaw"
Dab tsi' s ntxiv, ua cov perovskite muaju yog sib piv yooj yim." Lawv tuaj yeem tsim tawm los ntawm cov kua ua kua, yog li koj tuaj yeem tsim qhov xav tau ib txheej ntawm ib lub sijhawm ntawm qhov ncaj ncaj"
Thawj lub hnub ci hlwb los ntawm lub tshuab luam ntawv inkjet, tam sim no teeb duab hluav taws xob diodes dhau
Cov kws tshawb fawb ntawm HZB tau qhia nyob rau xyoo tas los no lub hnub ci tuaj yeem luam tawm los ntawm kev daws teeb meem ntawm cov khoom siv hluav taws xob semiconductor - thiab yog cov thawj coj thoob ntiaj teb hauv cov tshuab no niaj hnub no. Tam sim no thawj zaug, pab pawg sib koom ua ke ntawm HZB thiab HU Berlin tau ua tiav nyob rau hauv kev tsim cov hluav taws xob ua haujlwm zoo rau lub sijhawm. Cov pab pawg tshawb nrhiav siv cov hlau halide perovskite rau lub hom phiaj no. Qhov no yog cov khoom siv uas cog lus tshwj xeeb kev ua haujlwm zoo hauv kev tsim hluav taws xob - tab sis ntawm txhais tes yog qhov nyuaj rau txheej txheem.
GG quot; Txog tam sim no, nws tseem tsis tau tsim cov hom semiconductor txheej nrog qhov zoo txaus los ntawm kev siv kua" ;, hais Sau-Kratochvil. Piv txwv li, LEDs tuaj yeem luam tawm tsuas yog los ntawm cov organic semiconductors, tab sis cov no tsuas yog hnav lub teeb nrig me me." Qhov kev sib tw yog yuav ua li cas thiaj ua rau cov ntsev zoo li ntawv tau teev tseg uas peb tau luam tawm rau hauv txheej txheej kom tawg tau sai thiab nrawm los ntawm kev siv qee yam kev ntxim nyiam lossis catalyst" ;, piav txog tus kws tshawb fawb. Pab pawg tau xaiv cov noob siv lead ua rau lub hom phiaj no: lub ntsej muag ntsev uas muaj kev sib haum xeeb rau nws tus kheej mus rau txheej txheej qis thiab ua rau cov pob zeb tsim ua kom muaj kab mob rau tom ntej perovskite.
Tseem ceeb zoo dua cov cim kho qhov muag thiab hluav taws xob
Nyob rau hauv txoj kev no, cov kws tshawb fawb tsim cov ntawv luam tawm LED uas muaj lub teeb pom kev zoo dua thiab muaj cov hluav taws xob zoo dua li yav dhau los ua tiav siv cov txheej txheem tsim cov khoom ntxiv. Tab sis rau Sau-Kratochvil, qhov kev vam meej no tsuas yog ib qib lus nruab nrab ntawm txoj kev mus rau yav tom ntej micro- thiab optoelectronics uas nws ntseeg tias yuav ua raws tshwj xeeb ntawm hybrid perovskite semiconductors." Cov txiaj ntsig tau muab los ntawm cov kev kawm thoob ntiaj teb los ntawm cov khoom siv thiab ib tus nqi tsim nyog thiab cov txheej txheem yooj yim rau kev tsim khoom txhua yam ntawm cov khoom siv yog pom" ;, hais tias tus kws tshawb fawb. Yog li nws thiaj li npaj qhov kawg tsim txhua yam khoom siv hluav taws xob zoo li no hauv lub chaw soj nstuam HZB thiab HU Berlin.
