Tlhaloso e Khutšoanyane:

Li-Ingots tsa LiTaO3 (Lithium Tantalate Ingots), e le thepa ea mantlha bakeng sa li-semiconductor tsa moloko oa boraro tse nang le lekhalo le leholo la bandgap le li-optoelectronics, li sebelisa mocheso oa tsona o phahameng oa Curie (607).°C), sebaka se pharaletseng sa ponaletso (400–5,200 nm), coefficient e ntle ea ho kopanya ea electromechanical (Kt² >15%), le tahlehelo e tlase ea dielectric (tanδ <2%) ho fetola puisano ea 5G, computing ea quantum, le kopanyo ea photonic. Ka mahlale a tsoetseng pele a tlhahiso joalo ka lipalangoang tsa mouoane oa 'mele (PVT) le chemical vapor deposition (CVD), re fana ka li-ingots tsa X/Y/Z-cut, 42°Y-cut, le periodic poled (PPLT) ka litlhaloso tsa 3–8-inch, tse nang le micropipe density <0.1 cm⁻² le dislocation density <500 cm⁻². Litšebeletso tsa rona li kenyelletsa Fe/Mg doping, proton exchange waveguides, le silicon-based heterogeneous integration (POI), e sebetsanang le li-filter tsa optical tse sebetsang hantle, mehloli ea leseli la quantum, le li-infrared detectors. Thepa ena e khanna katleho ho miniaturization, ts'ebetso ea maqhubu a phahameng, le botsitso ba mocheso, e potlakisa phetoho ea lehae le tsoelo-pele ea theknoloji.

Litšebeletso tsa XKH

1. Tlhahiso ea Ingot e Kholo.

Boholo le ho Seha: Li-ingot tsa lisenthimithara tse 3–8 tse nang le X/Y/Z-cut, 42°Y-cut, le li-angular cut tse ikhethileng (± 0.01° tolerance).

Taolo ea ho sebelisa lithethefatsi: Ho sebelisa lithethefatsi tse ling tsa Fe/Mg ka mokhoa oa Czochralski (sebaka sa mahloriso 10¹⁶–10¹⁹ cm⁻³) ho ntlafatsa khanyetso ea photorefractive le botsitso ba mocheso.

2. Mekhoa e Tsoetseng Pele ea Ts'ebetso.

Ho Kopanya ho sa Tšoaneng: Li-wafer tse kopantsoeng tsa LiTaO3 tse thehiloeng ho Silicon (POI) tse nang le taolo ea botenya (300–600 nm) le tsamaiso ea mocheso ho fihlela ho 8.78 W/m·K bakeng sa li-filter tsa SAW tse nang le maqhubu a phahameng.

Tlhahiso ea Waveguide: Mekhoa ea phapanyetsano ea proton (PE) le reverse proton exchange (RPE), e finyellang li-waveguide tsa submicron (Δn >0.7) bakeng sa li-modulator tsa electro-optic tse lebelo le phahameng (bandwidth >40 GHz).

3. Mekhoa ea Tsamaiso ea Boleng

Teko ea ho Qetela: Raman spectroscopy (netefatso ea polytype), XRD (kristalinity), AFM (mofuta oa bokaholimo), le teko ea ho tšoana ha optical (Δn <5×10⁻⁵).

4. Tšehetso ea Ketane ea Phepelo ea Lefatše

Bokgoni ba Tlhahiso: Tlhahiso ya kgwedi le kgwedi > di-ingot tse 5,000 (8-inch: 70%), tse tshehetsang phano ya tshohanyetso ya dihora tse 48.

Marangrang a Thepa: Ho kenyeletsoa Europe, Amerika Leboea, le Asia-Pacific ka thepa ea moea/leoatle ka liphutheloana tse laoloang ke mocheso.

5. Nts'etsopele-mmoho ea Tekheniki

Li-Lab tsa R&D tse Kopaneng: Sebetsa 'moho liforomong tsa kopanyo ea photonic (mohlala, ho kopanya lera la SiO2 le tahlehelo e tlase).

Kakaretso

Li-Ingots tsa LiTaO3 li sebetsa e le thepa ea maano e fetolang theknoloji ea optoelectronics le ea quantum. Ka boqapi ba kholo ea kristale (mohlala, PVT), ho fokotsa liphoso, le kopanyo e fapaneng (mohlala, POI), re fana ka litharollo tse tšepahalang haholo le tse theko e tlaase bakeng sa puisano ea 5G/6G, k'homphieutha ea quantum, le IoT ea indasteri. Boitlamo ba XKH ba ho ntšetsa pele phokotso ea liphoso tsa ingot le ho holisa tlhahiso ea lisenthimithara tse 8 bo netefatsa hore bareki ba etella pele liketane tsa phepelo ea lefats'e, ba khanna mehla e latelang ea li-ecosystem tsa semiconductor tse nang le bandgap e kholo.
