Te pānga o te diode silicon carbide kaha-teitei kiPūoko Whakaahua PIN
Ko te diode PIN silicon carbide kaha-teitei tētahi o ngā wāhi rongonui i roto i te ao rangahau taputapu hiko. Ko te diode PIN he diode tioata i hangaia mā te whakapiri i tētahi paparanga o te semiconductor ā-roto (he semiconductor rānei he iti te kukū o ngā poke) i waenganui i te rohe P+ me te rohe n+. Ko te i i roto i te PIN he whakarāpopototanga Ingarihi mō te tikanga o te "ā-roto", nā te mea kāore e taea te noho hei semiconductor parakore me te kore he poke, nō reira ko te paparanga I o te diode PIN i roto i te tono he mea whakaranu ki te iti o ngā poke momo-P, momo-N rānei. I tēnei wā, ko te nuinga o te diode PIN silicon carbide e whakamahi ana i te hanganga Mesa me te hanganga papatahi.
Ina neke atu te auau whakahaere o te tīoata PIN i te 100MHz, nā te pānga rokiroki o ētahi kaikawe me te pānga wā whakawhiti i te paparanga I, ka ngaro te pānga whakatikatika o te tīoata ka noho hei huānga ārai, ā, ka huri tōna uara ārai me te ngaohiko piro. I te kore piro, i te piro whakamuri DC rānei, he tino teitei te ārai i te rohe I. I te piro whakamua DC, ka whakaatuhia e te rohe I he āhua ārai iti nā te werohanga kaikawe. Nō reira, ka taea te whakamahi i te tīoata PIN hei huānga ārai taurangi, i roto i te mara o te whakahaere ngaruiti me te RF, he maha ngā wā e tika ana kia whakamahia ngā taputapu whakawhiti hei whakatutuki i te whakawhiti tohu, inā koa i roto i ētahi pokapū whakahaere tohu auau-tiketike, he pai ake ngā kaha whakahaere tohu RF o ngā tīoata PIN, engari he whānuitia hoki te whakamahinga i roto i te nekehanga wāhanga, te whakarerekētanga, te whakawhāiti me ētahi atu ara iahiko.
He whānuitia te whakamahinga o te diode silicon carbide mana-teitei i roto i te mara hiko nā te mea he pai ake ōna āhuatanga ātete ngaohiko, ā, ko te nuinga o te wā ka whakamahia hei ngongo whakatikatika mana-teitei.PIN diodeHe teitei te ngaohiko pakaru whakamuri VB, nā te iti o te paparanga i whakakī i waenganui e kawe ana i te maturuturunga ngaohiko matua. Mā te whakanui ake i te matotoru o te rohe I me te whakaiti i te kukū whakakī o te rohe I ka taea te whakapai ake i te ngaohiko pakaru whakamuri o te diode PIN, engari mā te aroaro o te rohe I ka whakapai ake i te maturuturunga ngaohiko whakamua VF o te taputapu katoa me te wā whakawhiti o te taputapu ki tētahi whānuitanga, ā, ka taea e te diode i hangaia mai i te rauemi silicon carbide te whakakapi i ēnei ngoikoretanga. Ko te silicon carbide he 10 ngā wā o te mara hiko pakaru nui o te silicon, kia taea ai te whakaiti i te matotoru o te rohe diode silicon carbide I ki te kotahi-tekau o te ngongo silicon, me te pupuri tonu i te ngaohiko pakaru teitei, me te kawe wera pai o ngā rauemi silicon carbide, karekau he raruraru tohatoha wera e kitea ana, no reira kua riro te diode silicon carbide mana-teitei hei taputapu whakatikatika tino nui i roto i te mara o ngā hikohiko mana hou.
Nā te iti o te rerenga whakamuri me te nui o te nekehanga kawe, he nui te kukume o ngā diode silicon carbide i roto i te mara o te kimi whakaahua-hiko. Ka taea e te rerenga iti te whakaiti i te ia pōuri o te pūoko me te whakaiti i te haruru; Ka taea e te nekehanga kawe teitei te whakapai ake i te aro o te silicon carbide.Pūoko PIN(PIN Photodetector). Mā ngā āhuatanga mana-teitei o ngā diode silicon carbide ka taea e ngā pūoko PIN te kite i ngā pūtake mārama kaha ake, ā, e whakamahia whānuitia ana i te ao tūroa. Kua arohia te diode silicon carbide mana-teitei nā ōna āhuatanga pai rawa atu, ā, kua tino whanakehia hoki āna rangahau.
