Sannadkii hore, kooxda Sheng Zhigao, oo ah cilmi-baare ka tirsan Xarunta Sare ee Magnetic Field Center ee Machadka Hefei ee Sayniska Jirka, Akademiyada Shiinaha ee Sayniska, ayaa horumariyay terahertz modulator-ka-dhabta ah ee firfircoon iyo caqli-gal ah oo ku tiirsan tijaabada goobta magnetic-ka ee joogtada ah. qalab. Cilmi-baarista waxaa lagu daabacay ACS Applied Materials & Interfaces.
In kasta oo tignoolajiyada terahertz ay leedahay astaamo muuqaal sare leh iyo rajooyin codsi oo ballaadhan, codsigeeda injineernimada ayaa wali si dhab ah u xaddidan horumarinta agabka terahertz iyo qaybaha terahertz. Waxaa ka mid ah, xakamaynta firfircoon iyo caqliga leh ee hirarka terahertz ee goobta dibadda waa jihada cilmi-baarista ee muhiimka ah ee goobtan.
Iyadoo la higsanaayo jihada cilmi baadhista cidhifka ah ee qaybaha xudunta u ah terahertz, kooxda cilmi baadhistu waxay soo saartay terahertz modulator stress ku salaysan graphene laba-geesoodka ah [Adv. Qalabka indhaha. 6, 1700877(2018)], Modulator sawir qaade Terahertz broadband oo ku salaysan oksaydhka sida aadka ah ula xidhiidha [ACS Appl. Mater. Inter. 12, Kadib 48811 (2020)] iyo phonon-ku-saleysan hal-frequency magnetic-controlled terahertz isha [Sayniska Sare 9, 2103229(2021)], filimka elektiroonigga ah ee vanadium dioxide ee laxiriira waxaa loo xushay lakabka shaqeynaya, qaab dhismeedka lakabyo badan. naqshadeynta iyo habka kontoroolka elektaroonigga ah ayaa la qaatay. Hababka firfircoon ee kala duwan ee gudbinta terahertz, milicsiga iyo nuugista waa la gaarey (Jaantuska a). Natiijooyinku waxay muujinayaan in marka lagu daro gudbinta iyo nuugista, marxaladda milicsiga iyo milicsiga ayaa sidoo kale si firfircoon loogu xakameyn karaa beerta korantada, taas oo qoto-dheeraanta naqshadaynta muraayadda ay gaari karto 99.9% iyo marxaladda milicsiga waxay gaari kartaa ~ 180o modulation (Jaantus b) . Si aad u xiiso badan, si loo gaaro kontoroolka korantada ee terahertz, cilmi-baarayaashu waxay naqshadeeyeen qalab leh novel "terahertz - Electric-terahertz" jawaab celin celin (Jaantus c). Iyadoo aan loo eegin isbeddelada xaaladaha bilawga ah iyo deegaanka dibadda, qalabka casriga ah wuxuu si toos ah u gaari karaa qiimaha beddelka terahertz (la filayo) qiyaastii 30 ilbiriqsi.
(a) Jaantuska jaantuska ee amodulator optic ahku salaysan VO2
(b) isbeddelada gudbinta, milicsiga, nuugista iyo marxaladda milicsiga oo la yaab leh
(c) jaantuska jaantuska xakamaynta caqliga
Horumarinta terahertz firfircoon oo caqli badanmodulator elektaroonik ahku salaysan qalabka elektarooniga ah ee la xidhiidha waxay siinaya fikrad cusub xaqiijinta terahertz kantaroolka caqliga leh. Shaqadan waxaa taageeray Barnaamijka Horumarinta iyo Cilmi-baarista Muhiimka ah ee Qaranka, Aasaaska Sayniska Dabiiciga ah ee Qaranka iyo Sanduuqa Jihada Shaybaarka Goobta Sare ee Magnetic ee Gobolka Anhui.
