Kev Sib Txuas Lus Kev Sib Txuas Lus Kev Sib Txuas Lus, Ultra-Pinter Realonator
Kev rov kho kho qhov muag tau tuaj yeem ua ntu zus tshwj xeeb ntawm lub teeb pom ntawm lub teeb pom kev hauv qhov chaw tsawg, thiab muaj cov ntawv thov tseem ceeb hauv teeb tsa-teeb tsa hauv kev sib cuam tshuam teeb pom kev zoo,Kev Sib Txuas Lus, kho qhov muag pom, thiab kev sib xyaw ua ke. Qhov luaj li cas ntawm tus resonator tsuas yog nyob ntawm cov khoom ntiag tug thiab cov kev ua haujlwm ua haujlwm nyob rau hauv ze rau qhov chaw nyob ib feem ntau ntawm cov nanometers thiab saum toj no. Nyob rau hauv xyoo tsis ntev los no, Ultra-nyias lub ntiaj teb kho qhov muag resonators tau nyiam ntau dua vim lawv cov ntawv thov kev sib raug zoo, cov khoom lag luam nruab nrab, cov khoom siv hluav taws xob teeb. Yuav ua li cas kom txo cov tuab ntawm cov phiajcim resonators yog ib qho teeb meem nyuaj ntsib los ntawm cov kws tshawb nrhiav.
Txawv los ntawm cov khoom sib txawv ntawm cov ntaub ntawv slicationconductor, cov neeg muaj yees duab 3D kev qhia, thiab lwm yam) yog cov ntaub ntawv muaj kev tiv thaiv tshiab nrog cov khoom siv hluav taws xob saum npoo av thiab cov xeev insulator. Lub xeev muaj kev tiv thaiv los ntawm cov symmetry ntawm lub sij hawm inversion, thiab nws cov hluav taws xob tsis tawg ntawm cov kev cia siab rau cov kev cia siab hauv cov khoom siv qis thiab cov khoom siv hluav taws xob. Tib lub sijhawm, cov ntaub ntawv insulator tseem qhia tau cov khoom kho tshiab zoo heev, xws li lub siab ua kom siab tshiab, cov tsis muaj zogntawm qhov muagcoefficient, dav ua hauj lwm spectrum ntau, tunability, yooj yim kev sib koom ua ke, thiab lwm yam.Optoelectronic li.
Ib pab neeg tshawb fawb hauv Suav teb tau npaj siab rau txoj kev ntawm ultra-thinator resonators los ntawm kev siv cov chaw tsim kho tshiab ultra Lub cev kho qhov noj kab noj hniav pom pom qhov tshwm sim resonance responance nyob ze rau cov qhab-nees. Bismuth qhia tawm muaj lub siab ua haujlwm siab ntau tshaj 6 hauv kev sib txuas lus kho qhov muag thiab cov khoom siv hluav taws xob ua kom ncav cuag ib-nees nkaum ntawm cov resonance yoj. Nyob rau tib lub sijhawm, tus resical resonator tau muab tso rau ntawm ib-seem hluav taws xob crystal, uas yog vim kev sib txuas lus ntawm tus neeg rov ua haujlwm nrog tus tammooj ntawm lub resonior nrog tus tammooj ntawm tus neeg sib txuas lus nrog tus tammus ntawm tus neeg sib txuas lus nrog tus tammooj ntawm tus neeg muab kev cuam tshuam nrog tus menyuam yaus thiab nws txoj kev cuam tshuam tammooj Cov. Cov lus teb rau kev pom ntawm cov nyhuv no yog nyob ntawm qhov tuab ntawm lub resical resonator thiab yog robust rau kev hloov ntawm qhov chaw dav dav. Cov haujlwm no qhib txoj kev tshiab rau kev paub txog cov txheej txheem ultrathin ensulator cov ntaub ntawv kev cai thiab Optoelectronic li.
Raws li qhia hauv Daim Duab. 1a thiab 1b, resonical resonator feem ntau yog tsim ntawm cov bismuth qhia insulator insulator thiab nyiaj nanofils. Bismuth qhia rau NanoFilms npaj los ntawm Moteletron Sputtering muaj thaj chaw loj thiab muaj kev zoo nkauj. Thaum lub thickness ntawm bismuth qhia thiab nyiaj zaj duab xis yog 42 nm, feemxyog kab noj cov khoom pov tseg muaj zog nyob rau hauv pawg ntawm 1100 ~ 1800 nm (daim duab 1c). Thaum cov kws tshawb fawb sib xyaw ua ke cov kab noj qab zib tshiab rau ntawm ib qho kev hloov pauv ntawm Ta2o5 (180 nm) tshwm sim nyob ze ntawm thawj tus neeg rov ua haujlwm tseem ceeb (~ 1550 nm), uas yog zoo ib yam li hluav taws xob hluav taws xob tsis pom kev zoo ua rau muaj cov txiaj ntsig atomic.

Cov khoom siv bismuthuride tau cov cim los ntawm kev kis tau hluav taws xob electron micbipsometry. Daim duab. 2A-2C qhia kev kis tau hluav taws xob Micrographs (muaj cov duab hluav taws xob muaj kev sib txawv ntawm cov kab mob sib txawv ntawm NanoFilms. Nws tuaj yeem pom los ntawm daim duab uas npaj Bismuth qhia tawm NanoFilms yog polycrystalline cov ntaub ntawv, thiab cov kev loj hlob tseem ceeb yog (015) Crystal dav hlau. Daim duab 2D-2F qhia cov ntsiab lus tsis zoo ntawm Bismuth qhia thawj zaug los ntawm Ellipsometer thiab lub xeev haum refardating hais tias index. Cov txiaj ntsig qhia tau hais tias tus txiav txim siab coefficient ntawm lub xeev yog ntau dua li cov kev ntsuas siab dua ntawm 230 ~ 1930 nm, qhia cov yam ntxwv hlau zoo li. Cov ntaub ntawv qhia txog lub cev ntau tshaj 6 thaum lub nthwv dej ntau dua 1385 nus ua hauj lwm ntau dua li ntawm silicon, uas lays ib lub hauv paus rau kev npaj ntawm ultra -thuaj kho kho qhov muag resonators. Cov kws tshawb nrhiav taw qhia tias qhov no yog thawj zaug qhia txog Insulator Insulator ofulator ofcatical kab noj kab noj hniav ntawm tsuas yog kaum ntawm nanometers hauv kev sib txuas lus kho qhov muag. Tom qab, qhov nqus tau zoo nkauj thiab rov qab wavelength los ntawm ultra-nyias kho qhov muag tau ntsuas nrog cov tuab ntawm bismuth qhia. Thaum kawg, cov nyhuv ntawm nyiaj zaj duab xis thickness ntawm electromagnetically indicency spectra nyob rau hauv bismhocality introlity / potonic siv lead ua qauv tau tshawb xyuas

Los ntawm kev npaj thaj chaw loj cov yeeb yaj kiab ntawm Bismuth qhia cov khoom siv ultra, thiab coj kev qhia txog ultra Lub ultra-nyias cov kab ke tuaj yeem paub cov resonant lub teeb nqus tau zoo nyob rau hauv kev txhim kho Optoelectronic khoom siv hauv kev sib txuas lus band. Lub thickness ntawm bismuth qhia tawm qhov kho kab noj hniav kho dua tshiab, thiab me dua li cov silicon thiab cov khoom siv hluav taws xob zoo sib xws. Nyob rau tib lub sijhawm, Bismuth qhia tawm qhov kho Crystal tawm nrog lub tshuab hluav taws xob zoo ib yam li cov khoom siv hluav taws xob zoo sib xws, uas muab txoj kev tshiab rau cov kev tswj hwm tshiab ntawm microstructure. Txoj kev kawm no ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa cov kev tshawb fawb ntawm cov ntaub ntawv insulator hauv lub teeb thiab cov khoom siv kho kom zoo nkauj.
