Cov kev tshawb fawb kawg ntawm cov emgodetectors

Cov kws tshawb nrhiav tau tsim thiab pom cov teeb ntsuab tshiab nqus pob tshab cov organic photoDetectors uas yog rhiab heev thiab cmos manufacturing txoj kev. Ua ke cov ntawv tshiab no rau hauv silicone hybrid cov duab sensors yuav muaj txiaj ntsig rau ntau daim ntawv thov. Cov ntawv thov no suav nrog cov txheej txheem kev soj ntsuam lub plawv dhia fair kev xyuas, cov khoom siv ntiv tes thiab cov khoom siv uas pom tias muaj cov khoom nyob ze.

Txawm hais tias siv hauv smartphones lossis keeb kwm txuj ci keeb kwm, kev paub thev naus laus zis ntau tshaj plaws niaj hnub no hloov cov cim hluav taws xob. Txawm hais tias photodetectors ua los ntawm cov organic cov ntaub ntawv yog nyiam txhim kho cov kev paub zoo, nws muaj tau ua pov thawj nyuaj los tsim cov kev ua tau zoo organic photodetectors.

Co-Leade Cov Kws Tshawb Xyuas Sungojun Park, los ntawm Ajou University Parkic Phothodetectors uas yog qhov yooj yim ntawm cov duab orgo ntawm tus ncej tus nqi siab hauv qhov tsaus ntuj. Peb tau tsim pob tshab, ntsuab rhiab raphic photodes uas tuaj yeem ua tau raws li cov kev xav tau no. "

Cov kws tshawb nrhiav piav qhia txog cov edgicator tshiab hauv phau ntawv ceev xwm Optica. Lawv kuj tsim lub hybrid rgb tsom sensor los ntawm superimosing pob tshab ntsuab packodiode nrog cov ntxaij lim dej liab thiab xiav.

Kyung-Bae Chaw Ua Si, cov thawj coj ntawm pab pawg tshawb fawb los ntawm cov lus qhia txog kev tshawb fawb txog cov organic Nyob rau hauv cov duab duab sensors zoo heev txo cov crostalk ntawm cov xim sib txawv, thiab qhov kev tsim qauv tshiab no tuaj yeem ua rau cov tshuaj orgodes loj ntawm kev ntsuas cov qauv thiab cov duab rau cov duab ntau cov ntawv thov. "

Ntau Cov Tswv Yim Cov Ntaub Ntawv OrgoDetectors

Cov ntaub ntawv organic tsis haum rau huab hwm coj ntau lawm vim lawv rhiab heev rau qhov kub thiab txias. Lawv txawm tsis tuaj yeem tiv thaiv qhov kub siab siv rau kev kho mob tom qab lossis tsis ruaj khov thaum siv thaum kub ntev ntev. Yuav kom kov yeej qhov kev sib tw no, cov kws tshawb nrhiav tau tsom mus kho cov txheej ntawm cov txheej txheem ntawm cov photodetector los txhim kho ruaj khov, ua haujlwm, thiab nrhiav. Dhuav tau yog kev ntsuas ntawm yuav ua li cas zoo ib qho kev ntsuas tuaj yeem tshawb pom cov cim tsis muaj zog. "Peb qhia txog da dej tooj liab kab (BCP): C60 Lub photodetector tuaj yeem tso rau ntawm lub thawv silicon nrog lim liab thiab xiav xiav los tsim cov duab ntawm cov duab sensor.

Cov kws tshawb nrhiav qhia tau tias cov ntawv sau ua haujlwm tshiab cov qauv ntsuas cov nqi sib piv rau cov ntawm cov pa ntxig rau cov photodes. Cov ntes ua haujlwm ruaj khov rau 2 teev ntawm qhov kub siab tshaj 150 ° C thiab pom kev ua haujlwm ntev rau 30 hnub ntawm 85 ° C. Cov photodetectors no tseem qhia tau xim zoo xim.

Tom ntej no, lawv npaj yuav kho cov duab tshiab tshiab thiab cov duab ua kom zoo nkauj (xws li CMOS cov duab), cov khoom siv hluav taws xob, thiab cov khoom siv ntiv tes, thiab ntiv tes ua haujlwm nyob rau hauv.
