Paura Matotoru Kakariki Silicon Carbide: Te Whetu Aranga o ngā Kaihoroi Mahi-Tiketike
I tēnei rā, kia haere tonu tā tātou kōrero mō tētahi atu kaitākaro whakaharahara i roto i te whānau nanakia—paura moroiti karawiti silicon matomato. Ko tā mātou o te umanga e kī ana ko te "Hulk" anake, ā, kāore mātou e whakaaro he ingoa whakarihariha; he rite tonu ōna āheinga ki taua taitara. Nō nā tata nei mātou i kōrero whānui mō te alumina mā kua whakaranua; he rite ki tētahi tohunga toi ātaahua o te kooti, e whakaputa ana i ngā mahi ataahua me te ma. Engari ko te "Hulk" o ēnei rā he rite ake ki tētahi hēnerara matua e oma ana ki te pakanga, e tohunga ana ki ngā pakanga uaua me te aro atu ki ngā wero tino uaua. He aha i kiia ai ko te "whetu e ara ake ana"? Ko te take tuatahi ko tōna "pakeke."
Ko te karāhe silicon matomato te mea tino pakari i roto i ngā mea whakakoi noa, ko tōna pakeke Mohs he 9.5, he iti iho i te taimana. Kaua e whakaititia tēnei rerekētanga 0.5 i runga ake ialumina kua hanumi mā; ina mahi tahi me ētahi rauemi tino mārō, he tino rerekētanga nui. Kei te puta tonu mai ngā rauemi hou: ngā uku silicon carbide, te konumohe nitride, te karāhe hapaira, ngā papa silicon photovoltaic, te carbide sima—he mārō ake ia mea i te mea o mua. He rite te whakamahi i ngā mea whakakoi noa ki te waru i te kōhatu ki te pepa rino—he uaua, ā, he koretake.
Engari me te paura iti karāhe silicon carbide matomato, he tika tonu. Ko ōna taha koi, motuhake, he rite ki ngā taputapu tapahi taimana iti, e "ngaungau" ana i ēnei rauemi uaua. Ina koa i roto i te umanga photovoltaic, te tapahi i aua poro silicon monocrystalline me polycrystalline mārō me te pakarukaru, ka kite koe e whakamahia ana i roto i te nuinga o ngā raina whakaputa. Ki te kore, kāore e whakaitihia ngā utu me te whai huatanga o te whakaputa. Koinei te mea e kiia nei e koe ko te "whakangū i tētahi mea ki tētahi atu."
Hei tāpiritanga, he tino pai rawa atu tōna kawe wera.
He tino pai tēnei rauemi hei kawe wera. He painga nui tēnei i roto i ngā tukanga huri. Whakaarohia, ka puta he wera nui i te huri tere tonu. Ki te kore e taea e tēnei wera te memeha, ā, ka mau ki roto i te mea mahi, he kino rawa atu: ka ngāwari te mata o te mea mahi ki te "wera" me te ngatata; ka wera pea ngā wāhanga whakarewa, ka rerekē te pakeke; ā, ka hē pea ngā ine o ngā wāhanga tino tika nā te whānui me te whakahekenga wera.
He rite te mahi a te paura iti karāhe silicon kakariki ki tētahi "pūnaha whakamarara wera iti" kua hangaia ki roto, e tere ana te kawe i te wera mai i te rohe huri, ā, ka whakaitihia te pāmahana o te wāhi tukatuka. Mā tēnei ka whakaitihia te kino o te mea mahi i puta mai i te wera nui, ka whakarite i te kounga tukatuka. He āhuatanga tino nui tēnei, inā koa mō ngā rauemi me ngā wāhanga e tino pāngia ana e te wera.
Hei tāpiritanga, mā tōna āhuatanga "whakakoi-ā-ia anō" ka noho koi tonu te mahi.
Ehara ngā mea whakakoi pai i te hua "kotahi noa iho"; me roa te wā. Ahakoangā matūriki karāhe silicon matomatoHe mārō, he pakarukaru hoki, i raro i te kaha o te huri, ka pakaru ngā matūriki kua memenge, ka puta mai ngā taha hou, koi ake hei mahi tonu. Ka kiia tēnei āhuatanga ko te "whakakoi-ā-ia-anō".
He rite tēnei ki te whakamahi i te pene mīhini; ina memeha, ka pēhia anō, ā, ka puta mai he pene hou hei haere tonu i te tuhi. Ko te tikanga, puta noa i te tukatuka katoa, ka noho hou tonu, ka kaha tonu tōna kaha tapahi, ā, kāore e memeha haere i te roanga o te wā. He pumau te pai o te tukatuka, ā, he ōrite te kounga o te mata o te mea mahi, ka karo i te āhuatanga ka pai ake te kounga i te tīmatanga engari ka heke i muri mai. He mea nui tēnei mō te whakaputanga aunoa hou, nui, ā-tauine.
Tukua ahau kia kōrero atu i tētahi kōrero pono.
I te tau kua hipa, i whakapā mai tētahi wheketere e hanga ana i ngā pūwero miihini mahi-teitei ki ahau. He mea hanga ā rātou pūwero ki ngā uku motuhake he tino pakeke. He koretake rawa te whakamahi i ngā mea whakakoi noa mō te tukatuka, he nui rawa te utu, he iti iho rānei te kounga o te mata, he maha ngā wā ka kitea he pakaru iti. I muri mai, ka whakamātau rātou ki te whakamahi i te paura silicon carbide matomato mō te huri pai me te whakakanapa, ā, i puta wawe ngā hua. Kāore i te piki noa te pai o te mahi mā te 30-40%, engari ko te mea nui, i raro i te karu hiko, tata kore e kitea te paparanga kino i runga i te mata o te mea mahi, ā, ka piki haere te tere hua. I muri mai ka tangi tō rātou rangatira, "Te āhua nei kāore i uaua te mahi; kāore mātou i whiriwhiri i ngā taputapu tika."
Koinei te kaha o te "Hulk"—i roto i tōna tohungatanga, ka taea e ia te whakaoti rapanga kāore e taea e ētahi atu.
Ae, kāore tēnei "rangatira matua" i te kore he āhuatanga rerekē. Ahakoa he uaua, he ngoikore tōna pakari, ā, he pakarukaru. Nō reira, ina whakamahia ētahi rauemi pakari-teitei, pērā i ētahi maitai, kāore pea e rite tana mahi ki te alumina ma kua whakakotahihia kia pakari ake. Hei tāpiri, ko tōna tae kakariki emerara i ahu mai i te iti o ngā poke; i roto i ngā tukanga whakakanapa haurua-haurua motuhake e hiahia ana ki te tino parakore o te matū, tera pea ka hiahiatia ngā rauemi parakore ake. Engari kāore tēnei e whakaiti i tōna tūranga matua i roto i te tukatuka o ngā rauemi pakeke me te pakarukaru.
Nā te aha i kiia ai he "whetu e ara ake ana"? Tirohia noa ngā au o te umanga o nāianei me ngā mea kei te heke mai: ngā semiconductors o te whakatupuranga tuatoru (karāhe silicon, gallium nitride), te pūngao hou photovoltaic, ngā uku rererangi, te karāhe whatu kounga teitei… he maha o ēnei ahumahi sunrise e whakawhirinaki ana ki ngā rauemi tukatuka matua he mārō, he pakarukaru hoki. Ko te paura moroiti silicon carbide matomato tētahi o ngā taputapu tino pai me te whai hua mō te whakatau i ēnei raruraru uaua.
Ka tipu haere tōna pūmanawa i te taha o ēnei ahumahi hangarau matatau. I te whanaketanga tonu o ēnei ahumahi, ka noho tonu te hiahia mō te paura iti silicon carbide matomato teitei ake te mahi. Kei te rangahau tonu hoki tā mātou ahumahi whakakoi me pēhea te hanga i ōna matūriki kia ōrite ake, kia pai ake ai te maimoatanga o tōna mata, kia tiaho ake ai i tēnei wā whai hua.
