Kua roa te hiraka e noho ana hei poutokomanawa mō te hangarau haurua-ira. Heoi, i te mea ka piki haere ngā kiato o ngā transistors, ā, ka nui haere tonu ngā kiato mana o ngā tukatuka me ngā kōwae hiko hou, ka pāngia ngā rauemi e ahu mai ana i te hiraka e ngā herenga taketake i roto i te whakahaere wera me te pumau ā-pūkaha.
Karāhe siliconKo te (SiC), he haurua-āputa whānui, e tuku ana i te kawe wera nui ake me te pakari ā-mīhini, me te pupuri tonu i te pumau i raro i te mahi pāmahana teitei. E tūhuratia ana e tēnei tuhinga te āhua o te whakawhiti mai i te silicon ki te SiC e hanga hou ana i te takai maramara, e akiaki ana i ngā rapunga whakaaro hoahoa hou me ngā whakapainga mahi taumata-pūnaha.
1. Te Ahurea Wera: Te Whakatika i te Ārai o te Whakamarara Wera
Ko tētahi o ngā wero matua o te takai maramara ko te tango tere i te wera. Ka taea e ngā tukatuka me ngā taputapu hiko teitei te whakaputa rau ki te mano watts i roto i te wāhi kiato. Ki te kore he pai te tohatoha wera, ka puta ake ētahi take:
-
Ngā pāmahana hononga teitei e whakaiti ana i te roa o te ora o te taputapu
-
Te rerekētanga o ngā āhuatanga hiko, e whakararu ana i te pumau o te mahi
-
Te kohikohinga o te ahotea ā-mīhini, e arahi ana ki te pakaru, te rahunga rānei o te kete
Ko te kawe wera o te silicon he tata ki te 150 W/m·K, engari ko te SiC ka eke ki te 370–490 W/m·K, i runga i te whakatakotoranga tioata me te kounga o te rauemi. Mā tēnei rerekētanga nui ka taea e ngā takai SiC te:
-
Ka tere ake te kawe i te wera, ā, ka ōrite hoki
-
Ngā pāmahana hononga tihi iti iho
-
Whakaitihia te whakawhirinaki ki ngā otinga whakamatao o waho nunui
2. Te Pūmautanga Mīhini: Te Kī Huna ki te Pono o te Mōkihi
Haunga ngā whakaaro wera, me tu atu ngā takai maramara ki te huringa wera, te ahotea miihini, me ngā kawenga hanganga. He maha ngā painga o te SiC i te silicon:
-
Te modulus a Higher Young: E 2–3 ngā wā e pakari ake ai te SiC i te silicon, e ātete ana ki te piko me te whanoke
-
Te iti o te tauwehenga wera (CTE): Ko te pai ake o te taunga ki ngā rauemi takai ka whakaiti i te ahotea wera
-
Te pumau matū me te pāmahana tino pai: Ka mau tonu te pono i raro i ngā taiao makuku, pāmahana teitei, waikura rānei
Ka whai wāhi tika ēnei āhuatanga ki te pono me te hua mō te wā roa, inā koa i roto i ngā tono takai kaha-nui, matotoru-nui rānei.
3. He Huringa i roto i te Rapunga Whakaaro Hoahoa Takai
Ko ngā takai silicon tuku iho e whakawhirinaki nui ana ki te whakahaere wera o waho, pērā i ngā whakamahana wera, ngā pereti makariri, te whakamatao hohe rānei, ka hanga he tauira "whakahaere wera kore mahi". Ko te tango i te SiC ka tino whakarerekē i tēnei huarahi:
-
Te whakahaere wera whakauru: Ka huri te kete hei ara wera tino whai hua
-
Tautoko mō ngā mātotoru mana teitei ake: Ka taea te whakanoho tata atu i ngā maramara, te whakarārangi rānei, me te kore e neke atu i ngā rohe wera
-
He ngāwari ake te whakauru pūnaha: Ka taea te whakauru i ngā maramara maha me ngā maramara kanorau me te kore e whakararu i te mahi wera
Ko te tikanga, ehara te SiC i te "rauemi pai ake" anake—engari ka taea e ngā kaihangarau te whakaaro anō ki te tahora maramara, ngā hononga, me te hoahoa mōkihi.
4. Ngā Pānga mō te Whakaurunga Rerekē
Kei te piki haere te whakaurunga o ngā pūnaha haurua-ā-ira hou i ngā taputapu arorau, hiko, RF, tae atu ki ngā taputapu photonic ki roto i te kete kotahi. He rerekē ngā whakaritenga wera me ngā whakaritenga miihini o ia wāhanga. Ko ngā papa me ngā papa whakawhiti e hangai ana ki te SiC e whakarato ana i tētahi tūāpapa whakakotahi e tautoko ana i tēnei kanorau:
-
Ka taea e te kawe wera teitei te tohatoha wera ōrite puta noa i ngā taputapu maha
-
Mā te pakari ā-mīhini ka mau te pumau o te kete i raro i te whakarārangi matatini me ngā whakatakotoranga matotoru
-
Nā te hototahitanga ki ngā taputapu whānui-rohe ka tino pai te SiC mō ngā tono rorohiko hiko me te mahi teitei o te whakatupuranga e whai ake nei.
5. Ngā Whakaarohanga Hanga
Ahakoa he pai ake ngā āhuatanga o te rauemi SiC, nā tōna pakeketanga me tōna pumau matū ka puta mai ngā wero hanga ahurei:
-
Te angiangi o te anga me te whakarite i te mata: Me huri me te whakakanapa kia kore ai e pakaru, e piko rānei
-
Te hanganga me te tauira mā te mā te via: Ko ngā via ōwehenga-teitei e hiahia ana ki ngā tikanga whakairo maroke matatau, āwhina-reera rānei.
-
Te whakarewatanga me te honohono: Ko ngā ara hiko piripono me te iti-ātete e hiahia ana ki ngā paparanga ārai motuhake
-
Te tirotiro me te whakahaere hua: Ko te pakari o ngā rauemi me ngā rahi angiangi nui ka whakanui ake i te pānga o ngā hapa iti noa iho
He mea nui te angitu o te aro atu ki ēnei wero kia tino whai hua ai te SiC i roto i ngā takai mahi-teitei.
Whakamutunga
Ko te whakawhiti mai i te silicon ki te silicon carbide ehara i te mea he whakapai ake i ngā rauemi anake—ka hurihia te āhua katoa o te takai maramara. Mā te whakauru i ngā āhuatanga wera me te miihini pai rawa atu ki roto i te papa, i te papa rānei, ka taea e te SiC te whakanui ake i te kaha o te mana, te whakapai ake i te pono, me te ngāwari ake i roto i te hoahoa taumata-pūnaha.
I te mea kei te pana tonu ngā taputapu haurua-ira i ngā rohe o te mahi, ehara ngā rauemi e hangai ana ki te SiC i te mea he whakarei ake i ngā kōwhiringa anake—he mea matua hoki hei whakahohe i ngā hangarau tākai o te whakatupuranga e whai ake nei.
