I le tausaga talu ai, o le au a Sheng Zhigao, o se tagata suʻesuʻe i le High Magnetic Field Center o le Hefei Institute of Physical Sciences, Chinese Academy of Sciences, na atiina ae se malosi ma atamai terahertz electro-optic modulator faʻalagolago i le faʻataʻitaʻiga o le maneta maualuga maualuga. masini. Ole su'esu'ega o lo'o fa'asalalau ile ACS Applied Materials & Interfaces.
E ui lava o tekonolosi terahertz e sili atu ona uiga mata'utia ma lautele avanoa fa'aoga, o lona fa'aaogaina fa'ainisinia o lo'o fa'atapula'aina lava i le atina'eina o mea fa'aoga ma vaega terahertz. Faatasi ai ma i latou, o le malosi ma le atamai pulea o galu terahertz i fafo fanua o se itu taua suʻesuʻega i lenei vaega.
O le fa'amoemoe i le fa'ata'ita'iga o su'esu'ega fa'ata'ita'iga o vaega 'autu o terahertz, Ua fa'atupuina e le au su'esu'e se fa'atonuga fa'avevesi terahertz e fa'avae i luga o le graphene mea e lua-dimensional [Adv. Optical Mater. 6, 1700877(2018)], o le Terahertz broadband photocontrolled modulator e faʻavae i luga o le oxide malosi fesoʻotaʻi [ACS Appl. Mata. Inter. 12, A maeʻa le 48811(2020)] ma faʻavae phonon-faʻavae fou e tasi-auala maneta-pulea terahertz puna [Advanced Science 9, 2103229(2021)], o le ata eletonika oxide vanadium dioxide e fesoʻotaʻi e filifilia e avea ma vaega galue, fausaga faʻapipiʻi tele. mamanu ma auala faaeletonika pulea ua faaaogaina. E mafai ona fa'aogaina le fa'aogaina o le terahertz, mafaufauga ma le fa'aogaina (Ata a). O faʻaiʻuga o loʻo faʻaalia ai i le faaopoopo atu i le transmittance ma absorptivity, o le reflectivity ma le vaega o mafaufauga e mafai foi ona faʻatonutonu malosi e le eletise eletise, lea e mafai ai ona oʻo atu i le 99.9% le loloto o le faʻaogaina o le faʻaogaina ma le vaega o mafaufauga e mafai ona oʻo atu i le ~ 180o modulation (Ata b) . O le mea e sili ona manaia, ina ia ausia le atamai o le terahertz eletise, na mamanuina e le au suʻesuʻe se masini ma se tala fou "terahertz - electric-terahertz" tali faʻaalia (Ata c). E tusa lava po o le a le suiga i tulaga amata ma le siosiomaga i fafo, e mafai e le masini atamai ona otometi lava ona oʻo atu i le seti (faʻamoemoeina) terahertz modulation tau pe a ma le 30 sekone.

(b) suiga ole fe'avea'i, fa'amana'o, fa'aoso ma le fa'ata'ita'iga vaega fa'atasi ai ma le a'ave fa'amalosi
(c) ata fa'ata'atia o le fa'atonuga atamai
Le atina'eina o se terahertz malosi ma atamaifa'aogaina eletise eletisefaʻavae i luga o mea faʻaeletoroni fesoʻotaʻi e maua ai se manatu fou mo le faʻataunuʻuina o le pulea atamai o terahertz. O lenei galuega na lagolagoina e le National Key Research and Development Programme, le National Natural Science Foundation ma le High Magnetic Field Laboratory Direction Fund a le Anhui Province.
