Kufotokozera Kwachidule:

LiTaO3 Wafer (lithium tantalate wafer), chinthu chofunikira kwambiri mu semiconductors ndi optoelectronics za m'badwo wachitatu, chimagwiritsa ntchito kutentha kwake kwakukulu kwa Curie (610°C), broad transparency range (0.4–5.0 μm), superior piezoelectric coefficient (d33 > 1,500 pC/N), ndi low dielectric loss (tanδ < 2%)kuti chisinthe kulumikizana kwa 5G, photonic integration, ndi zida za quantum. Pogwiritsa ntchito ukadaulo wapamwamba wopanga monga physical vapor transport (PVT)ndi chemical vapor deposition (CVD), XKH imapereka ma X/Y/Z-cut, 42°Y-cut, ndi periodically poled (PPLT)wafers mu mawonekedwe a 2–8-inch, okhala ndi surface roughness (Ra) <0.5 nm ndi micropipe density <0.1 cm⁻². Ntchito zathu zikuphatikizapo Fe doping, chemical reduction, ndi Smart-Cut heterogeneous integration, kuthana ndi ma high-performance optical filters, infrared detectors, ndi quantum light sources. Zinthuzi zimapangitsa kuti zinthu zisinthe pang'ono, kugwiritsa ntchito pafupipafupi kwambiri, komanso kukhazikika kwa kutentha, zomwe zimathandizira kusintha kwa zinthu m'nyumba m'maukadaulo ofunikira.

Makhalidwe Ofunika

1. Magwiridwe Amagetsi ndi Owona
· Electro-Optic Coefficient: r33 imafika 30 pm/V (X-cut), 1.5× kuposa LiNbO3, zomwe zimathandiza kuti ultra-wideband electro-optic modulation (>40 GHz bandwidth).
· Broad Spectral Response: Kutumiza kwa ma transmission mtunda wa 0.4–5.0 μm (kukhuthala kwa 8 mm), ndi m'mphepete mwa ultraviolet yoyamwa yotsika kufika 280 nm, yoyenera ma UV lasers ndi zida za quantum dot.
· Koefficient Yotsika ya Pyroelectric: dP/dT = 3.5×10⁻⁴ C/(m²·K), kuonetsetsa kuti masensa a infrared okhala ndi kutentha kwambiri ndi olimba.

2. Katundu wa Kutentha ndi Makina
· Kutentha Kwambiri: 4.6 W/m·K (X-cut), kanayi kuposa kwa quartz, kupirira kutentha kwa -200–500°C.
· Kuchuluka kwa Kutentha Kochepa: CTE = 4.1×10⁻⁶/K (25–1000°C), imagwirizana ndi ma CD a silicon kuti ichepetse kupsinjika kwa kutentha.
3. Kuwongolera ndi Kukonza Zolakwika Mwachangu
· Kuchuluka kwa Micropipe: <0.1 cm⁻² (ma wafer a mainchesi 8), kuchuluka kwa dislocation <500 cm⁻² (kutsimikiziridwa kudzera mu KOH etching).
· Ubwino wa pamwamba: CMP-yopukutidwa mpaka Ra <0.5 nm, ikukwaniritsa zofunikira za EUV lithography-grade flatness.
