Hunhu Hunokosha

1. Kushanda Kwemagetsi Nemaziso
· Electro-Optic Coefficient: r33 inosvika 30 pm/V (X-cut), 1.5× yakakwirira kupfuura LiNbO3, zvichiita kuti ultra-wideband electro-optic modulation (>40 GHz bandwidth).
· Broad Spectral Response: Kupararira kwesimba remagetsi kubva pa 0.4–5.0 μm (ukobvu hwe 8 mm), ne ultraviolet absorption edge yakaderera kusvika 280 nm, yakakodzera ma UV lasers ne quantum dot devices.
· Chiyero chePyroelectric Chishoma: dP/dT = 3.5×10⁻⁴ C/(m²·K), zvichiita kuti pave nekugadzikana mumasensa einfrared ane tembiricha yakakwira.

2. Zvimiro zveThermal uye Mechanical
· Kufambisa Kwekupisa Kwakanyanya: 4.6 W/m·K (X-cut), yakapetwa kana kupfuura yequartz, ichitsigira -200–500°C kupisa kunotenderera.
· Kuwedzerwa kweThermal Low: CTE = 4.1×10⁻⁶/K (25–1000°C), inoenderana nekurongedza kwesilicon kuderedza kushushikana kwekupisa.
3. Kudzora uye Kugadzirisa Zvikanganiso Kwazvo
· Kuwanda kweMicropipe: <0.1 cm⁻² (mawafers e-inch 8), kusimba kwedislocation <500 cm⁻² (zvakasimbiswa kuburikidza neKOH etching).
· Hunhu Hwepamusoro: CMP-yakapetwa kusvika Ra <0.5 nm, ichizadzisa zvinodiwa zveEUV lithography-grade flatness.
