1. Ngā Huarahi Hou i roto i te Whakarite Rauemi Parakore-Tiketike
Ngā Rauemi e Hangaia ana e te Hiraka: Kua neke atu te parakore o ngā tioata takitahi o te hiko i te 13N (99.9999999999%) mā te whakamahi i te tikanga rohe mānu (FZ), e whakarei ake ana i te mahi a ngā taputapu haurua-teitei (hei tauira, ngā IGBT) me ngā maramara matatau 45. Ka whakaitihia e tēnei hangarau te poke o te hāora mā te tukanga kore-para, ā, ka whakauruhia te silane CVD me ngā tikanga Siemens kua whakarerekētia hei whakatutuki i te whakaputanga whai hua o te polysilicon 47 e rewa ana i te rohe.
Ngā Rauemi Germanium: Nā te whakapainga o te horoinga rewa rohe kua piki ake te parakore o te germanium ki te 13N, me te whakapai ake i ngā tauwehenga tohatoha poke, ka taea ai te whakamahi i roto i ngā whatu infrared me ngā pūoko irahiko 23. Heoi, ko ngā taunekeneke i waenga i te germanium rewa me ngā rauemi taputapu i ngā pāmahana teitei he wero nui tonu 23.
2. Ngā Auahatanga i roto i ngā Tukanga me ngā Taputapu
Mana Tawhā Hihiri: Ko ngā whakarerekētanga ki te tere nekehanga o te rohe rewa, ngā pikinga pāmahana, me ngā taiao hau tiaki—me te aroturuki wā-tūturu me ngā pūnaha urupare aunoa—kua whakarei ake i te pumau o te tukanga me te auautanga, me te whakaiti i ngā taunekeneke i waenga i te germanium/silicon me ngā taputapu27.
Te Hanganga Polysilicon: Ko ngā tikanga tauine hou mō te polysilicon taumata-rewa-rohe e aro ana ki ngā wero whakahaere i te ihirangi hāora i roto i ngā tukanga tuku iho, e whakaiti ana i te whakapaunga pūngao me te whakanui ake i te hua47.
3. Te Whakaurunga Hangarau me ngā Whakamahinga Whakawhiti-Whaiaro
Whakaranu Whakakotahitanga Rewa: Kei te whakauruhia ngā tikanga whakakotahitanga rewa iti-pūngao hei arotau i te wehenga me te purenga o ngā matū waro, me te whakawhānui ake i ngā tono whakarewa rohe i roto i ngā takawaenga rongoā me ngā matū pai6.
Ngā Ārahi-whakatupuranga Tuatoru: Kei te whakamahia te whakarewa rohe ki ngā rauemi whānui-rohe pērā i te silicon carbide (SiC) me te gallium nitride (GaN), e tautoko ana i ngā taputapu auau-tiketike me te pāmahana-tiketike. Hei tauira, mā te hangarau oumu karaihe-kotahi-wāhanga-wai ka taea te tipu pumau o te karaihe SiC mā te whakahaere pāmahana tika15.
4. Ngā horopaki tono kanorau
Photovoltaics: Ka whakamahia te polysilicon taumata-rewa-rohe i roto i ngā pūtau rā tino whai hua, ka tutuki ai te pai o te tahuritanga hiko-whakaahua neke atu i te 26% me te akiaki i ngā whanaketanga i roto i te pūngao whakahou4.
Ngā Hangarau Pūwero me te Kimi: Mā te germanium tino-parakore ka taea e ngā taputapu whakaahua pūwero iti, mahi-teitei me te tirohanga pō te whakamahi mō ngā mākete hōia, haumarutanga, me te iwi whānui23.
5. Ngā Wero me ngā Aronga o te Ao
Ngā Herenga Tango i te Parakore: He uaua ki ngā tikanga o nāianei te tango i ngā parakore o ngā huānga mārama (hei tauira, te boron, te phosphorus), e hiahiatia ana he tukanga tāpiritanga hou, he hangarau whakahaere rohe rewa hihiri rānei25.
Te Pakari o ngā Taputapu me te Whai Hua o te Pūngao: Ko te arotahi o ngā rangahau ko te whakawhanake i ngā rauemi parai e ātete ana ki te pāmahana teitei, e ātete ana ki te waikura, me ngā pūnaha whakamahana auau irirangi hei whakaiti i te whakapaunga pūngao me te whakaroa i te roa o te oranga o ngā taputapu. E whakaatu ana te hangarau whakarewa pewa korehau (VAR) i te tumanako mō te whakapai ake i te konganuku 47.
Kei te ahu whakamua te hangarau whakarewa rohe ki te parakore teitei ake, te utu iti ake, me te whakamahinga whānui ake, e whakakaha ana i tana tūranga hei tūāpapa i roto i ngā semiconductors, te pūngao whakahou, me ngā optoelectronics
