'Chithandizo cholimba' chobisika mu mafakitale apamwamba: Kodi mphamvu ya matabwa a sikweya a silicon carbide ndi yolimba bwanji?

Mu uvuni wotentha kwambiri wa mafakitale komanso malo olondola opangira zinthu zopangidwa ndi semiconductor, pali chinthu chapadera chomwe chimawoneka ngati chachilendo koma chofunikira kwambiri - silicon carbide square beam. Sichikuwoneka bwino ngati zinthu zomaliza, koma chifukwa cha magwiridwe ake apadera, chakhala "choteteza chosawoneka" cha madera ambiri opanga zinthu zapamwamba. Lero, m'mawu osavuta, tikukudziwitsani za chinthu chatsopanochi chomwe chili ndi luso lapadera.
Ubwino waukulu wamatabwa a sikweya a silicon carbideChimachokera ku mtundu wapadera wa silicon carbide yake yaiwisi. Chida ichi, chomwe chimapangidwa ndi silicon ndi zinthu za kaboni, chilibe zinthu zambiri zachilengedwe ndipo chimapangidwa mwaluso kwambiri m'mafakitale. Kuuma kwake ndi kwachiwiri kwa diamondi ndipo ndi kolimba kwambiri kuposa zipangizo zachikhalidwe zachitsulo. Pambuyo pochikonza kukhala chozungulira, chimawonjezera ubwino wake wazinthu ndipo chimakhala "munthu wolimba" wokhoza kupirira malo ovuta kwambiri.
Kukana kutentha kwambiri ndi ntchito yapadera ya silicon carbide square beams. M'mafakitale ophikira pa madigiri Celsius masauzande ambiri, zitsulo wamba zimakhala zofewa kale komanso zosinthika, pomwe silicon carbide square beams zimatha kusunga mawonekedwe awo mosalekeza ndipo sizingasinthe chifukwa cha kutentha kwambiri. Mphamvu iyi ya "kukana kutentha kwambiri" imapangitsa kuti ikhale chisankho chabwino kwambiri pazochitika zomwe zimafuna ntchito zotentha kwambiri, popanda kusinthidwa pafupipafupi, zomwe zimachepetsa kwambiri kutayika kwa kupanga.
Kuwonjezera pa kukana kutentha kwambiri, "kukana kwake kupanga" kumaonekeranso mu kukana dzimbiri ndi mphamvu zambiri. M'malo opangira mafakitale, n'kosapeweka kukumana ndi zinthu zowononga monga asidi ndi alkali. Pamwamba pa matabwa a silicon carbide square amatha kupanga filimu yoteteza yokhazikika kuti isagonjetse kuukira kwa mankhwala osiyanasiyana ndipo sidzachita dzimbiri kapena kuwonongeka. Nthawi yomweyo, ndi yopepuka koma ili ndi mphamvu yolimba yonyamula katundu. Monga kapangidwe ka zida zonyamula katundu, imatha kuonetsetsa kuti ikuthandizira bwino popanda kuwonjezera katundu wambiri pazida zonse, komanso imachepetsa kugwiritsa ntchito mphamvu.

Kuyambira zothandizira uvuni zoyatsira ceramic, mpaka zothandizira zofunika kwambiri popanga semiconductor, komanso zida zopirira kutentha kwambiri m'munda wa mphamvu zatsopano, matabwa a silicon carbide square amapezeka m'mafakitale ambiri ofunikira. Alibe kapangidwe kovuta, koma amathetsa mavuto omwe zipangizo zachikhalidwe sizingathe kuthana nawo ndi ntchito yabwino, kukhala mwala wofunikira kwambiri panjira yopititsa patsogolo kupanga zinthu zapamwamba.
Ndi kupita patsogolo kosalekeza kwa ukadaulo watsopano, njira zogwiritsira ntchito matabwa a silicon carbide square zikukulirakulirabe. "Chithandizo cholimba" chobisikachi chikuthandiza mwakachetechete chitukuko chapamwamba cha mafakitale osiyanasiyana chifukwa cha kulimba kwake, kukhazikika, komanso kudalirika kwake, kukhala mphamvu yosawoneka koma yofunika kwambiri yaukadaulo.
