Lub Initial Arrangement Ntawm Cov Kua Siv Tshuaj Crystal Molecules

Dec 16, 2017

1. Lub qauv ntawm cov qauv kua nematic kua nchuav (raws li muaj nyob hauv daim duab 5) .Qhov qauv ntawm cov khoom siv ua kua nematic kua dej (raws li qhia hauv daim duab 5).

Cov iav hauv qab iav muaj ob qho zoo lithography cov qauv hluav taws xob sib txuas hauv cov qauv uas tau tso tawm ua ke, qhov nrug yog 6 ~ 7 m, khi nrog epoxy resin ncig, tab sis nyob ntawm ib sab ntawm lub sealing ntug tawm hauv qhov qhib los ntawm lub tshuab nqus cov kua dej ua kua, ces qhov ncauj kaw nrog kua nplaum. Lub taub haus dej ua kua dej, thiab tom qab ntawd cov iav uas siv sab nrauv sab nrauv, orthogonal nrog polarizer, ua kua dej ua kua siv tau ua rau ob qho tiav.

Rau TN kua Crystal zaub, ib txheej txheej ntawm qhov yuav tsum ua rau sab hauv ntawm cov kua siv lead ua kua, kom cov kua siv lead ua kua molecules muaj txheej txheem ntawm lub hauv ntej thiab nram qab iav txheej substrate.

Qhov nruab nrab ntawm kev coj kav ntev ntawm kua siv lead ua kua molecules rau ntawm sab xub ntiag thiab rov qab ob iav substrates kuj yog orthogonal.


2. Lub xub pib ntawm kua crystal molecules

Lub hauv paus ntsiab lus ntawm cov kua hluav taws xob hauv cov kua hluav taws xob, hauv cov hluav taws xob, thermal teb nyob rau hauv qhov kev txiav txim ntawm cov kua siv lead ua kua molecules los ntawm lub xeev thawj zaug ntawm lub xeev kev hloov ntawm cov txheej txheem, nrog rau kev hloov ntawm molecular kev kho, kua siv ua kua hloov tau hloov, yog li hloov los mus hloov cov kev hloov qhov muag pom, ua lub hom phiaj ntawm cov duab tso tawm, yog li thawj zaug ua kom sib luag ntawm cov kua siv lead ua molecules lub cev thiab kev ruaj ntseg ntawm cov kua siv lead ua kua zaub yog lub hauv paus ua haujlwm.

Muaj 7 yam ntawm cov kua siv lead ua kua molecular tshiab, raws li qhia hauv daim duab 6.

Cov nram qab no yog ib qho lus piav qhia yooj yim ntawm cov kev sib txawv ntawm cov kua siv lead ua kua ntau yam.

(1) kev tsim kho ntawm cov kab ntsig ntawm lub plhaub: tag nrho cov kua siv lead ua kua molecules raug teeb tsa ntawm ob sab ntawm ob tog.

(2) kev tsim cov molecules nyob rau saum npoo: tag nrho cov kua siv lead ua kua molecules yog mus tib seem rau lub hauv paus sab nraud ntawm ob sab thiab raug teeb tsa hauv qhov kev taw qhia.

(3) kev npaj ntawm cov qauv khov kho: tag nrho cov kua siv lead ua kua molecules muaj siab rau ntawm lub kaum sab xis ntawm ob sab ntawm lub qhov ntxa, thiab tau npaj rau tib txoj kev.

(4) sib xyaw molecular kev kho: cov kua siv lead ua kua molecules yog teem rau ntawm ib sab ntawm lub substrate, thaum nyob rau sab nraud, sab ntsej muag ntawm cov kua kua dej yog sib npaug txheej txheem ntawm tib qho kev coj, yog li cov txheej txheem ntawm cov kua siv lead ua kua molecules yog 90 degrees tsis tu ncua nruab nrab ntawm ob lub substrates.

(5) kev kho molecular kev kho: tag nrho cov kua siv lead ua kua molecules yog cov txheej txheem sib npaug ntawm ob sab ntawm cov substrate, tab sis cov kev taw qhia ntawm ob daim ntawm cov tombs yog 90 degrees, vim li no cov lus sib dhos ntawm cov kua siv lead ua kua molecules yog 90 degree ntawm ob lub substrates.

(6) muaj kev sib txuam nrog cov nplaum: lub dav hlau qwj ua kom haum los ntawm cov kua siv lead ua kua molecules yog vertically teem rau ntawm ob sab ntawm lub substrate.

(7) kev tsim ntawm lub cones: lub axis muab ntawm cov kua siv lead ua kua rau hauv cov lus sib dhos rau ob sab ntawm lub tojntxas ntawm ob sab, tab sis qhov kev coj ntawm txoj siab khau yog qhov tsis paub meej.
