Sharaxaad Gaaban:

LiTaO3 Wafer (lithium tantalate wafer), walxaha muhiimka ah ee jiilka saddexaad ee semiconductors iyo optoelectronics, waxay ka faa'iideysataa heerkulkeeda sare ee Curie (610 ° C), daah-furnaan ballaaran (0.4-5.0 μm), iskudhafka piezoelectric sare (d33> 1,500 pC / N), iyo isgaarsiin hooseeya <2. is dhexgalka photonic, iyo qalabka quantum. Isticmaalka tignoolajiyada wax soo saarka ee horumarsan sida gaadiidka uumiga jirka (PVT) iyo kaydinta uumiga kiimikaad (CVD), XKH waxay bixisaa X/Y/Z-cut, 42°Y-cut, iyo PPLT) wafers oo ah qaabab 2-8-inch ah, oo muujinaya qallafsanaanta dusha sare (Ra) <0.5 nm iyo cufnaanta micropipe. Adeegyadayagu waxa ay ka kooban yihiin Fe-doping, kiimikaad dhimis, iyo is dhexgalka kala duwan ee Smart-Cut, wax ka qabashada shaandhada indhaha ee waxqabadka sare leh, qalabka wax baadha infrared, iyo ilaha iftiinka quantum. Qalabkani waxa uu horseedaa horumarada yaraynta, hawlgalka soo noqnoqda sare, iyo xasiloonida kulaylka, dardargelinta beddelka gudaha ee tignoolajiyada muhiimka ah.
