Ngā Āhuatanga

Kupu Whakataki Matua: Te Tūranga o ngā Wafer HPSI SiC i roto i ngā Mōhiti AI/AR

Ko ngā papa HPSI (Teitei-Parakore Āhua-Whakamaroke) Silicon Carbide he papa motuhake e tohuhia ana e te ātete teitei (>10⁹ Ω·cm) me te tino iti o te kiato hapa. I roto i ngā mōhiti AI/AR, ko rātou te rauemi matua mō ngā karāhe arataki whatu diffractive, e whakatika ana i ngā arai e pā ana ki ngā rauemi whatu tuku iho e pā ana ki ngā āhuatanga āhua angiangi me te mārama, te tohatoha wera, me te mahi whatu. Hei tauira, ka taea e ngā mōhiti AR e whakamahi ana i ngā karāhe arataki SiC te whakatutuki i te tirohanga whānui rawa (FOV) o te 70°–80°, me te whakaiti i te matotoru o te paparanga karāhe kotahi ki te 0.55mm anake me te taumaha ki te 2.7g anake, e whakarei ake ana i te whakamarie mau me te rumaki tirohanga.

Ngā Āhuatanga Matua: Te Whakakaha a te Rauemi SiC i te Hoahoa Mōhiti AI/AR

Teitei o te Taupū Whakaata me te Arotautanga o te Mahi Whatu

Ko te taupū whakaata o te SiC (2.6–2.7) e tata ana ki te 50% teitei ake i te karāhe tuku iho (1.8–2.0). Mā tēnei ka taea te hanga i ngā hanganga arataki ngaru angiangi ake, whai hua ake hoki, ka nui ake te whakawhānui i te FOV. Ka āwhina hoki te taupū whakaata teitei ki te pehi i te "pānga āniwaniwa" e kitea ana i roto i ngā arataki ngaru whakarara, ka whakapai ake i te parakore o te ahua.

Te Pūmanawa Whakahaere Wera Tino Pai

Me te kawe wera e tae atu ana ki te 490 W/m·K (tata ki te parahi), ka taea e te SiC te tere te whakamarara i te wera e puta mai ana i ngā kōwae whakaaturanga Micro-LED. Mā tēnei ka ārai i te hekenga o te mahi, te koroheketanga rānei o te taputapu nā te pāmahana teitei, ka roa ai te ora o te pākahiko me te pumau.

Te Kaha me te Pūmau o te Mīhini

Ko te pakeke o te SiC he 9.5 (tuarua ki te taimana), ā, he tino ātete ki te rakuraku, he mea pai mō ngā mōhiti e whakamahia pinepinetia ana. Ka taea te whakahaere i tōna taratara mata ki te Ra < 0.5 nm, kia iti ai te ngaronga me te tino ōrite o te tuku mārama i roto i ngā arataki ngaru.

Hototahitanga o ngā Āhuatanga Hiko

Mā te ātete o te HPSI SiC (>10⁹ Ω·cm) ka ārai i te pokanoa o te tohu. Ka taea hoki e ia te mahi hei rauemi taputapu hiko whai hua, hei whakapai ake i ngā kōwae whakahaere hiko i roto i ngā mōhiti AR.

Ngā Tohutohu Tono Matua

Ngā Wāhanga Whatu Matua mō ngā Karāhe AI/ARngā

Ngā Arotahi Arataki Ngaru Whakarerekē: Ka whakamahia ngā papa SiC hei hanga i ngā arataki ngaru whatu tino angiangi e tautoko ana i te FOV nui me te whakakore i te pānga āniwaniwa.
Ngā Pereti Matapihi me ngā Porowhita: Mā te tapahi me te oro ritenga, ka taea te tukatuka i te SiC hei matapihi tiaki, hei porowhita whatu rānei mō ngā mōhiti AR, hei whakarei ake i te whakawhiti mārama me te ātete ki te kakahu.

Ngā tono whānui i roto i ētahi atu mara

Hikohiko Mana: Whakamahia i roto i ngā āhuatanga auau-tiketike, mana-tiketike pērā i ngā kaitahuri waka pūngao hou me ngā mana whakahaere motuka ahumahi.
Whatu Irahiko: He wāhi noho mō ngā pokapū tae, e whakamahia ana i roto i ngā papa mō ngā whakawhitiwhiti kōrero irahiko me ngā taputapu pūoko.
