Ingota Karaihe Kotahi Hapaira tikanga ky Al2O3

Whakaahua Matua o te Ingota Karaihe Kotahi o te Hapaira Al2O3 tikanga ky

Whakaahuatanga Poto:

He tioata kotahi kounga teitei te karaihe hapaira i ahu mai i te waikura konumohe parakore (Al₂O₃) mā te whakamahi i te tikanga Kyropoulos (KY) me ētahi atu tikanga kukume matatau. Ko te hua o te ingota porotaka, te ingota whakarara rānei, he mata maeneene, he matotoru, ā, he iti noa ngā hapa o roto. Nā te mea he tino pai ngā āhuatanga whatu, miihini, me te matū, kua noho te hapaira hei rauemi matua mō ngā hikohiko opto, ngā semiconductors, me ngā hikohiko kaihoko kounga teitei.

Ngā Āhuatanga Matua

Tino Pakari
- Ko te pakeke Mohs he 9, ko te tuarua anake i te taimana.
- Ko te ātete tino pai ki te rakuraku me te kakahu e whakarite ana i te roa o te ora ratonga.
Mahi Tirotiro Tino Pai
- Te whakawhiti teitei (≥85%) mai i ngā roangaru ultraviolet ki te infrared (tata ki te 190 nm–5 µm).
- He pūmau te taupū whakaata i te 1.76, e āhei ai te whakaahua whatu me te tuku tika.
Ngā Āhuatanga Wera Tino Pai
- Mā te ira rewa teitei o te ~2050 °C ka taea te whakamahi pono i roto i ngā taiao pāmahana teitei.
- Mā te kawe wera pai (≈35 W/m·K i te pāmahana rūma) ka tautoko i te tohatoha wera pai.
Te Pūmautanga Matū Tino Pai
- Ātete ki ngā waikawa, ngā kawakore, te rehu tote, me te nuinga o ngā whakarewa waro.
- Ka noho puku matū tonu i roto i te korehau, i ngā hau puku, me ngā āhuarangi waikura, whakaiti rānei kaha.
Te Āheinga o te Tukanga me te Whakaōrite
- He ōrite te whānui o ngā tioata i tipuhia ki te KY, ā, he iti te ahotea o roto.
- Ka taea te tapahi, te whakakanapa, me te paninga kia rite ki ngā whakaritenga a te kiritaki, me te taratara o te mata he iti iho i te Ra ≤ 0.2 nm.

Ngā tono noa

Ngā Papa LED me ngā Papa Ārahi
- He turanga tino pai mō GaN, AlGaN, me ētahi atu rauemi epitaxial i roto i ngā LED kanapa-tiketike, ngā diode laser, me ngā taputapu hiko.
- Mā te kounga tioata pumau ka nui te hua me te roa o te ora o te taputapu.
Ngā Matapihi Whatu me te Pūwero-whero
- He pai mō ngā kāmera pūwero whero, ngā pūnaha LiDAR, me ngā matapihi pūoko rererangi.
- He pono te mahi i roto i ngā taiao uaua pērā i te pēhanga teitei, te onepu, te rehu tote moana rānei.
Ngā Hikohiko Kaihoko
- Ngā uhi mātaaratanga papai rawa atu, ngā parenga arotahi kāmera waea atamai, me ngā uhi pūoko tapumati.
- E whakakotahi ana i te māramatanga ataahua me te ātete tino pai ki te rakuraku.
Taputapu Ahumahi me te Pūtaiao
- Ngā peera tika, ngā pūwero ātete-kakahu, ngā tirohanga pēhanga teitei.
- Ngā wāhanga mō ngā taiaho mana-tiketike me ngā rangahau whatu matatau.

Ngā Pātai Auau

P1. He aha te mea i hangaia ai te karaihe hapaira kotahi?
A1. He mea hanga mai i te waikura konumohe parakore-teitei (Al₂O₃) i whakatipuria hei hanganga karaihe kotahi mā te whakamahi i te tikanga Kyropoulos (KY).

P2. He aha ngā whakatakotoranga tioata e wātea ana?
A2. Ko ngā aronga noa ko te papa-C (0001), te papa-A, me te papa-R. Ka taea e mātou te whakarite i te aronga kia rite ki ngā hiahia o tō pūrere.

Q3. He aha ngā rahi, ngā diameter rānei e taea ana e koe te tuku?
A3. Ko ngā diameter paerewa kei waenga i te 2 ki te 8 inihi, me te roa kei waenga i te 20 ki te 200 mm. Ka taea te whakaputa i ngā rahi nui ake, i ngā rahi motuhake rānei mēnā ka tonoa.

P4. Ka taea te whakamahi i te hapaira hei papa mō te tipu LED, GaN rānei?
A4. Āe. He iti te kiato o te nekehanga o ā mātou poro hapaira i whakatipuria ki KY, ā, he teitei te pumau o te wera, he mea tino pai mō ngā LED e hangai ana ki te GaN, ngā diode laser, me ētahi atu tono semiconductor.

Q5. He aha ngā āhuatanga whatu e whakaratohia ana e te hapaira?
A5. Neke atu i te 85% o te mārama e tukuna ana e te hapaira mai i te 190 nm i roto i te hihi UV ki te 5 µm i roto i te hihi infrared, me te taupū whakaata o te 1.76 pea.
