Karāhe hiraka (SiC)Ko te rauemi semiconductor te mea tino pakari i roto i ngā semiconductor whānui āputa roopu kua whakawhanakehia. He nui te kaha o ngā rauemi semiconductor SiC ki te whakamahi i roto i ngā taputapu pāmahana teitei, auau teitei, mana teitei, hikohiko whakaahua me te ātete i te hihi nā te mea he whānui te āputa roopu, he nui te papa hiko pakaru, he nui te kawe wera, he nui te nekehanga irahiko kua whakakiia me te rahi iti. He whānui ngā tono a te silicone carbide: nā te mea he whānui te āputa roopu, ka taea te whakamahi hei hanga i ngā diode marama kikorangi, i ngā pūoko ultraviolet rānei kāore e pāngia e te rā; nā te mea ka taea te manawanui i te ngaohiko, te papa hiko rānei e waru ngā wā i te silicon, i te gallium arsenide rānei, he tino pai mō te hanga i ngā taputapu mana teitei ngaohiko teitei pēnei i ngā diode ngaohiko teitei, te triode mana, te silicon controlled me ngā taputapu ngaruiti mana teitei; nā te mea he tere te hekenga irahiko kua whakakiia, ka taea te hanga hei momo taputapu auau teitei (RF me te ngaruiti);Karāhe siliconHe pai te kawe wera, ā, he pai ake tana kawe wera i tētahi atu rauemi haurua-ā-ira, e pai ai te mahi a ngā taputapu silicon carbide i ngā pāmahana teitei.
Hei tauira motuhake, kei te whakarite a APEI ki te whakawhanake i tana pūnaha taraiwa motuka DC taiao-tino mō te Venus Explorer (VISE) a NASA mā te whakamahi i ngā wāhanga silicon carbide. Kei roto tonu i te wāhanga hoahoa, ko te whāinga he tau i ngā karetao tūhura ki te mata o Venus.
Hei tāpiritanga,karāhe irikonaHe kaha te hononga irahiko ionic, he pakeke rawa, he kawe wera ki te parahi, he pai te mahi whakamarara wera, he tino kaha te ātete ki te waikura, he ātete ki te hihi, he ātete ki te pāmahana teitei me te pumau matū pai me ētahi atu āhuatanga, he whānuitia ngā tono i roto i te mara o te hangarau rererangi. Hei tauira, ko te whakamahinga o ngā rauemi silicon carbide hei whakarite i ngā waka rererangi mō ngā kairangi rererangi, ngā kairangahau ki te noho me te mahi.
