Qeexida Substrate-ka ee KTaO3
Substrate-ka KTaO3 (potassium tantalate) waxa loola jeedaa substrate crystalline oo ka samaysan isku dhafka potassium tantalate (KTaO3).
KTaO3 waa walxo perovskite ah oo leh qaab-dhismeedka crystal cubic oo la mid ah SrTiO3.Substrate-ka KTaO3 waxa uu leeyahay sifooyin ka dhigaya mid si gaar ah faa'iido ugu leh cilmi-baarista iyo codsiyada aaladaha kala duwan.Korantada sare ee joogtada ah iyo korantada wanaagsan ee KTaO3 ayaa ka dhigaysa mid ku habboon codsiyada sida capacitors, aaladaha xusuusta, iyo wareegyada elektiroonigga ah ee soo noqnoqda.Intaa waxaa dheer, KTaO3 substrates waxay leeyihiin sifooyin piezoelectric aad u fiican, taasoo ka dhigaysa inay faa'iido u leeyihiin codsiyada piezoelectric sida dareemayaasha, kiciyayaasha, iyo kuwa tamarta goosta.
Saamaynta piezoelectric waxay u ogolaataa substrate-ka KTaO3 inuu soo saaro kharashyo marka ay la kulmaan culeyska farsamada ama qallafsanaanta farsamada.Intaa waxaa dheer, substrates KTaO3 waxay muujin karaan ferroelectricity heerkulka hooseeya, taas oo ka dhigaysa mid ku habboon daraasadda fiisigiska walxaha isku dhafan iyo horumarinta qalabka xusuusta aan isbeddelayn.
Guud ahaan, substrate-yada KTaO3 waxay door muhiim ah ka ciyaaraan horumarinta qalabka elektiroonigga ah, piezoelectric, iyo ferroelectric.Hantidooda sida joogtada ah ee dielectric sare, korantada wanaagsan ee korantada, iyo piezoelectricity waxay ka dhigaan alaabta substrate-ka ugu fiican ee codsiyo kala duwan.
Qeexida Filimada Khafiifka ah ee Wanaagsan
Filim khafiif ah oo dhuuban waxaa loola jeedaa lakabka khafiifka ah ee walxaha leh dabeecadda sare, taas oo ah, awoodda lagu sameeyo koronto oo leh caabbinta eber.Filimadan waxaa sida caadiga ah lagu sameeyaa iyadoo lagu shubayo agabka awooda sare leh ee dulsaaran substrates iyadoo la adeegsanayo farsamooyin wax-abuuris oo kala duwan sida kaydinta uumiga jirka, kaydinta uumiga kiimikada, ama epitaxy molecular beam epitaxy.
