Ngā papa whakarewa SiC 3inihi 76.2mm 4H-Hapori-SiC, ngā papa whakarewa SiC whakakino-haurua Silicon Carbide

Ko ngā papa whakarewa SiC (silicon carbide) 3-inihi 4H he mea hanga ki te haurua-whakamaroke, he rauemi haurua-whakamaroke e whakamahia whānuitia ana. Ko te 4H e tohu ana i te hanganga tioata tetrahexahedral. Ko te tikanga o te haurua-whakamaroke he teitei ngā āhuatanga ātete o te papa whakarewa, ā, ka taea te wehe atu i te rere o te iahiko.

Ko ngā āhuatanga o ēnei papa whakarewa ko: te kawe wera nui, te ngaronga kawe iti, te ātete pāmahana teitei pai rawa atu, me te pumau ā-pūkaha me te matū pai rawa atu. Nā te mea he whānui te āputa pūngao o te silicon carbide, ā, ka taea e ia te tu atu i ngā pāmahana teitei me ngā āhuatanga o te mara hiko teitei, he whānui te whakamahinga o ngā papa whakarewa-haurua 4H-SiC i roto i ngā taputapu hiko mana me ngā taputapu auau reo irirangi (RF).

Ko ngā whakamahinga matua o ngā papa whakamātao-haurua 4H-SiC ko:

1--Te hikohiko mana: Ka taea te whakamahi i ngā anga 4H-SiC hei hanga i ngā taputapu whakawhiti mana pēnei i ngā MOSFET (Metal Oxide Semiconductor Field Effect Transistors), ngā IGBT (Insulated Gate Bipolar Transistors) me ngā diode Schottky. He iti ake ngā mate whakawhiti me te arataki o ēnei taputapu i roto i ngā taiao ngaohiko teitei me te pāmahana teitei, ā, he nui ake te pai me te pono.

2--Ngā Pūrere Auautanga Reo Irirangi (RF): Ka taea te whakamahi i ngā anga whakamātao-haurua 4H-SiC hei hanga i ngā whakakaha mana RF auau teitei, ngā ātete maramara, ngā tātari, me ētahi atu taputapu. He pai ake te mahi auau teitei me te pumau wera o te silicon carbide nā te nui ake o te tere o te rerenga irahiko me te kawe wera teitei ake.

3--Ngā taputapu hiko-whakaata: Ka taea te whakamahi i ngā anga whakamātao-haurua 4H-SiC hei hanga i ngā taiaho taiaho mana-teitei, ngā pūoko mārama UV me ngā ara iahiko whakauru hiko-whakaata.

Mō te ahunga o te mākete, kei te piki haere te hiahia mō ngā angaanga haurua-whakamarumaru 4H-SiC me te tipu haere o ngā mara hikohiko mana, RF me ngā hikohiko opto. Nā te whānuitanga o ngā tono a te silicon carbide, tae atu ki te whai huatanga o te pūngao, ngā waka hiko, te pūngao whakahou me ngā whakawhitiwhiti kōrero tēnei. I te heke mai, kei te tino whai hua tonu te mākete mō ngā angaanga haurua-whakamarumaru 4H-SiC, ā, e matapaetia ana ka whakakapi i ngā rauemi silicon tuku iho i roto i ngā tono maha.
