Txawm hais tias kev siv dav dav ntawm kev sib txuas lus kho qhov muag nrog cov transceivers thiab lasers, tag nrho cov ntaub ntawv kho qhov muag tseem yog ib qho kev tiv thaiv tsis pub lwm tus paub. Txoj kev tshawb fawb tshiab los ntawm pab pawg kws tshawb fawb los ntawm Russia thiab Great Britain yuav pab txhawb txoj hauv kev no. ib qho ntawm cov kev paub tsis meej ntawm qhov muaj zog sib cuam tshuam ntawm lub teeb thiab cov organic molecules.
Organics muaj cov kws tshawb fawb txaus siab rau qhov laj thawj. Kev hloov pauv ntawm cov kab mob hauv av yog inextricably txuas nrog kev sib cuam tshuam nrog lub teeb. Thiab kev sib raug zoo heev! Kev paub txog cov cai tseem ceeb ntawm cov kev sib txuas no yuav pab ua kom muaj kev vam meej hauv kev tsim cov khoom siv hluav taws xob raws li cov khoom siv organic. LEDs, lasers thiab qhov nrov OLED cov ntxaij vab tshaus tsuas yog qee qhov kev lag luam uas tuaj yeem ua kom lawv txoj kev loj hlob nrog kev paub tshiab.
Kev nkag siab txog qhov tshwm sim ntawm kev sib raug zoo ntawm lub teeb nrog cov organic molecules tau tsim los ntawm ib pab pawg kws tshawb fawb los ntawm Skoltech Hybrid Photonics Laboratory thiab University of Sheffield (UK). Cov hauv paus ntsiab lus ntawm kev sib txuas muaj zog muaj lub sijhawm tshwj xeeb rau kev ua cov ntaub ntawv kho qhov muag tag nrho yam tsis muaj qhov poob ntawm lub teeb liab ceev thiab lub zog thaum hloov mus rau tam sim no, uas tshwm sim niaj hnub no. Txoj kev tshawb no yog cov ntsiab lus ntawm ib tsab xov xwm hauv Nature Communications Physics (cov ntawv sau ua lus Askiv muaj pub dawb ntawm ).
Raws li cov kev tshawb fawb yav dhau los ntawm kev sib cuam tshuam ntawm lub teeb (photons) nrog cov teeb meem, cov kws tshawb fawb tau kawm txog "kev sib xyaw" ntawm photons nrog hluav taws xob excitation ntawm molecules, los yog excitons. Kev sib cuam tshuam ntawm photons nrog quasiparticles-excitons-ua rau pom ntawm lwm yam quasiparticles-polaritons. Polaritons ua ke nrog kev kub ceev ntawm lub teeb propagation thiab cov khoom hluav taws xob ntawm cov teeb meem. Cias muab, lub photon yog, raws li nws yog, materialized thiab acquires cov khoom nyob ze rau cov electron. Nrog rau qhov no lawm !
Raws li polariton, nws muaj peev xwm tsim tau lub transistor ua haujlwm thiab, yav tom ntej, processor. Xws li lub khoos phis tawj yuav tsis xav tau emitting thiab photoconverting sensors, uas muaj kev ua haujlwm qis thiab kev ua haujlwm qis, thiab pab pawg los ntawm Skoltech hnub no tau xaus rau qhov paub tsis meej ntawm kev sib cuam tshuam polariton.
"Nws paub los ntawm kev sim uas thaum polaritons condense nyob rau hauv cov organic teeb meem, ib tug ntse hloov nyob rau hauv spectral zog tshwm sim, thiab qhov kev hloov no ib txwm ua rau ib tug ntau ntawm cov zaus ntawm polaritons. Qhov no yog qhov qhia txog cov txheej txheem uas tsis yog-linear tshwm sim hauv lub cev, ib yam li, piv txwv li, kev hloov xim ntawm cov hlau thaum nws ua kom sov. "
Cov pab pawg tau soj ntsuam cov ntaub ntawv sim thiab tsim kom muaj qhov tseem ceeb ntawm kev hloov pauv ntawm polariton zaus ntawm qhov tseem ceeb tshaj plaws ntawm kev sib cuam tshuam ntawm lub teeb nrog cov organic molecules. Thawj thawj zaug, qhov muaj zog ntawm lub zog hloov pauv ntawm cov molecules nyob sib ze ntawm cov khoom tsis zoo ntawm cov polaritons tau pom. Qhov no qhia lub zog tsav tom qab polaritons. Paub txog qhov xwm txheej ntawm cov txheej txheem, nws muaj peev xwm los tsim txoj kev xav thiab paub meej tias nws nrog cov tswv yim thwmsim, piv txwv li, txuas ob peb polariton condensates rau hauv ib lub voj voog los tsim cov polariton processors.
