Ngā Āhuatanga Matua

1. Te Mahi Hiko me te Mahi Whatu
· Tauwehenga Hiko-Whiti: ka eke a r33 ki te 30 pm/V (X-cut), 1.5× teitei ake i te LiNbO3, ka taea ai te whakarerekētanga hiko-whatu whānui rawa (>40 GHz te whānui o te hononga).
· Urupare Whānui mō te Tirohanga: Te whānuitanga tuku 0.4–5.0 μm (matotoru 8 mm), me te taha mimiti hihi ultraviolet he iti iho i te 280 nm, he mea tino pai mō ngā taiaho UV me ngā taputapu ira kuantum.
· Tauwehenga Hiko Iti: dP/dT = 3.5×10⁻⁴ C/(m²·K), e whakarite ana i te pumau i roto i ngā pūoko pūwero whero-mahana teitei.

2. Ngā Āhuatanga Wera me te Āhuatanga Ā-Mīhini
· Te Awe Wera Teitei: 4.6 W/m·K (X-cut), e whā ngā whakarea o te quartz, e mau tonu ana i te huringa wera -200–500°C.
· Tauwehenga Whānui Wera Iti: CTE = 4.1×10⁻⁶/K (25–1000°C), hototahi ki te takai silicon hei whakaiti i te ahotea wera.
3. Te Whakahaere Hapa me te Tukatuka Tika
· Te Matotoru o te Paipa Makoro: <0.1 cm⁻² (ngā papa 8-inihi), te matotoru o te nekehanga <500 cm⁻² (i manatokohia mā te whakairo KOH).
· Kounga Mata: Kua orohia ki te CMP ki te Ra <0.5 nm, e tutuki ana i ngā whakaritenga papatahi o te EUV lithography.
