WhakauruhiaPūoko whakaahua InGaAs
Ko te InGaAs tētahi o ngā rauemi tino pai mō te whakatutuki i te urupare teitei me tepūoko whakaahua tere-teiteiTuatahi, he rauemi haurua whakawhiti tika te InGaAs, ā, ka taea te whakahaere i tōna whānui o te whakawhiti mā te ōwehenga i waenga i te In me te Ga, ka taea ai te kite i ngā tohu whatu o ngā roangaru rerekē. I roto i ēnei, he tino ōrite te In0.53Ga0.47As ki te whatunga papa InP, ā, he tino teitei te tauwehenga mimiti mārama i roto i te roopu whakawhitiwhiti whatu. Koinei te mea e whakamahia whānuitia ana i roto i te whakarite opūoko whakaahuaā, he tino pai rawa atu hoki te mahi o te au pōuri me te mahi urupare. Tuarua, he tino teitei te tere o te nekeneke irahiko o ngā rauemi InGaAs me InP, ā, ko ō rāua tere nekeneke irahiko kua kōtui tata ki te 1×107cm/s. I taua wā, i raro i ngā mara hiko motuhake, ka whakaatuhia e ngā rauemi InGaAs me InP ngā pānga tere irahiko, ā, ko ō rāua tere irahiko ka eke ki te 4×107cm/s me te 6×107cm/s. He pai ki te whakatutuki i te whānui whakawhiti teitei ake. I tēnei wā, ko ngā pūoko whakaahua InGaAs te pūoko whakaahua rongonui mō te whakawhitiwhiti whatu. I te mākete, ko te tikanga hononga taupatupatu mata te mea tino noa. Ka taea te whakaputa papatipu i ngā hua pūoko taupatupatu mata me te 25 Gaud/s me te 56 Gaud/s. Kua whakawhanakehia hoki ngā pūoko taupatupatu mata iti ake te rahi, taupatupatu whakamuri, me te whānui whānui teitei, ko te nuinga mō ngā tono pēnei i te tere teitei me te kōtui teitei. Heoi, nā ngā herenga o ā rātou tikanga honohono, he uaua te whakauru i ngā taputapu kite taupatupatu mata ki ētahi atu taputapu hiko-whakaata. Nō reira, i te pikinga ake o te hiahia mō te whakaurunga hiko-whakaata, kua noho haere ngā taputapu kite whakaahua InGaAs hono ngaru he pai te mahi, ā, he pai mō te whakauru hei kaupapa matua o te rangahau. I roto i ēnei, ko ngā waeine kite whakaahua InGaAs arumoni o te 70GHz me te 110GHz e whakamahi ana i ngā hanganga honohono ngaru. E ai ki te rerekētanga o ngā rauemi papa, ka taea te whakarōpū i ngā taputapu kite whakaahua InGaAs hono ngaru kia rua ngā momo: INP-based me Si-based. He kounga teitei te rauemi epitaxial i runga i ngā papa InP, ā, he pai ake mō te hanga taputapu mahi-teitei. Heoi, mō ngā rauemi rōpū III-V i whakatipuhia, i herea rānei ki runga i ngā papa Si, nā te maha o ngā rerekētanga i waenga i ngā rauemi InGaAs me ngā papa Si, he iti te kounga o te rauemi, o te atanga rānei, ā, he nui tonu te wāhi hei whakapai ake i te mahi a ngā taputapu.
Ko te pumau o te taputapu whakaahua i roto i ngā taiao tono maha, inā koa i raro i ngā āhuatanga tino kino, tētahi o ngā mea matua i roto i ngā tono mahi. I ngā tau tata nei, ko ngā momo taputapu hou pēnei i te perovskite, ngā rauemi rauropi me ngā rauemi rua-ahu, kua aro nui ki ēnei, kei te aro tonu ki ngā wero maha e pā ana ki te pumau mō te wā roa nā te mea he ngāwari te pāngia o ngā rauemi e ngā āhuatanga taiao. I taua wā, kāore anō kia pakari te tukanga whakauru rauemi hou, ā, me haere tonu te tūhuratanga kia nui te hanga me te pumau o te mahi.
Ahakoa ka taea e te whakaurunga o ngā inductors te whakanui ake i te whānui o ngā taputapu i tēnei wā, kāore i te rongonui i roto i ngā pūnaha whakawhitiwhiti kōrero matihiko. Nō reira, ko te huarahi hei karo i ngā pānga kino hei whakaiti ake i ngā tawhā RC pirinoa o te taputapu tētahi o ngā huarahi rangahau o te taputapu whakaahua tere-teitei. Tuarua, i te mea kei te piki haere tonu te whānui o ngā taputapu whakaahua hono ngaru, ka tīmata anō te puta mai o te here i waenga i te whānui me te urupare. Ahakoa kua pūrongohia ngā taputapu whakaahua Ge/Si me te taputapu whakaahua InGaAs me te whānui 3dB neke atu i te 200GHz, kāore i te pai ō rātou urupare. Ko te huarahi hei whakanui ake i te whānui me te pupuri tonu i te urupare pai he kaupapa rangahau nui, e hiahia ana pea ki te whakaurunga o ngā rauemi hou e hototahi ana ki te tukanga (te nekehanga teitei me te tauwehenga mimiti teitei) me ngā hanganga taputapu tere-teitei hou hei whakaoti. Hei tāpiri, i te mea ka piki haere te whānui o te taputapu, ka piki haere ngā āhuatanga tono o ngā taputapu whakaahua i roto i ngā hononga whakaahua ngaruiti. Kāore i rite ki te iti o te putanga mana whatu me te kitenga tairongo-teitei i roto i te whakawhitiwhiti kōrero whatu, ko tēnei āhuatanga, i runga i te whānui teitei, he nui te tono mana kukū mō te putanga mana-teitei. Heoi, ko ngā taputapu whānui-rahi te nuinga o te wā ka whakamahi i ngā hanganga iti, nō reira ehara i te mea ngāwari te hanga i ngā taputapu whakaahua tere-teitei me te kaha-mākū, ā, me whai auahatanga anō pea i roto i te tango kawe me te whakamarara wera o ngā taputapu. Hei whakamutunga, ko te whakaiti i te ia pōuri o ngā taputapu whakaahua tere-rahi he raruraru tonu me whakaoti e ngā taputapu whakaahua me te kore e ōrite te whatunga. Ko te ia pōuri te mea nui e pā ana ki te kounga tioata me te āhua o te mata o te rauemi. Nō reira, ko ngā tukanga matua pēnei i te heteroepitaxy kounga-teitei, te hononga rānei i raro i ngā pūnaha kore ōrite te whatunga me nui ake te rangahau me te haumi.
