Kua pania ki te silicon carbideKo te kōpae karāpiti he mea hanga hei whakarite i te paparanga tiaki karāpiti silicon ki runga i te mata o te karāpiti mā te whakatakoto i te kohu ā-tinana, ā-matū rānei, me te rehu. Ka taea te here pūmau i te paparanga tiaki karāpiti silicon kua whakaritea ki te anga karāpiti, kia mātotoru ai te mata o te turanga karāpiti, kia kore ai he āputa, kia hoatu ai ki te anga karāpiti ngā āhuatanga motuhake, tae atu ki te ātete ki te waikura, te ātete ki te waikawa me te kawakore, te ātete ki te horo, te ātete ki te waikura, me ētahi atu. I tēnei wā, ko te paninga Gan tētahi o ngā wāhanga matua pai rawa atu mō te tipu epitaxial o te karāpiti silicon.
Ko te haurua hiko waro hiko te rauemi matua o te haurua hiko whānui āputa hou. He āhuatanga o ōna taputapu ko te ātete pāmahana teitei, te ātete ngaohiko teitei, te auau teitei, te kaha teitei me te ātete irahiko. He painga ōna ko te tere whakawhiti tere me te tino whai hua. Ka taea e ia te whakaiti i te whakapaunga hiko hua, te whakapai ake i te whai huatanga o te hurihanga pūngao me te whakaiti i te rahinga hua. Ko te nuinga o te whakamahinga i roto i te whakawhitiwhiti kōrero 5g, te tiaki whenua me te umanga hōia. Ko te mara RF e tohuhia ana e te rererangi me te mara hikohiko mana e tohuhia ana e ngā waka pūngao hou me te "hanganga hou" he mārama, he nui hoki ngā tirohanga mākete i roto i ngā mara ā-iwi me te hōia.
Ko te papa hiko waro te rauemi matua o te haurua whakawhiti whānui-rohe hou. Ko te papa hiko waro te mea e whakamahia nuitia ana i roto i ngā hiko ngaruiti, ngā hiko mana me ētahi atu mara.Kei te pito o mua o te mekameka ahumahi haurua-āputa whānui, ā, koia te rauemi matua matua me te mata hou. Ka taea te wehewehe i te papa hiko waro ki ngā momo e rua: te haurua-whakamarumaru me te kawe hiko. I roto i ēnei, he teitei te ātete o te papa hiko waro haurua-whakamarumaru (ātete ≥ 105 Ω· cm). Ka taea te whakamahi i te papa hiko haurua-whakamarumaru me te pepa epitaxial gallium nitride heterogeneous hei rauemi mō ngā taputapu RF, e whakamahia nuitia ana i roto i te whakawhitiwhiti 5g, te tiaki whenua me te umanga hōia i ngā whakaaturanga o runga ake nei; Ko tētahi atu he papa hiko waro kawe hiko me te ātete iti (ko te awhe ātete he 15 ~ 30m Ω· cm). Ka taea te whakamahi i te epitaxy ōrite o te papa hiko waro kawe hiko me te hiko waro hei rauemi mō ngā taputapu hiko. Ko ngā horopaki tono matua ko ngā waka hiko, ngā pūnaha hiko me ētahi atu mara.
