He whakamārama poto mō te photodiode avalanche

He whakamārama poto mōte pūoro whakaahua horonga
He taputapu haurua-ā-ira tino tairongo te photodiode avalanche e huri ana i te mārama hei tohu hiko mā te pānga photovoltaic. He rerekē ki ngā tikanga tuku ihongā diode whakaahua, kua hangaia te APD kia mahi i raro i ngā ngaohiko whakamuri teitei e tata ana ki te ngaohiko pakaru, kia tutuki ai te whakareatanga ā-roto o te iahiko whakaahua mā te pānga pakaru o te awa. Ki te whakatauritea ki ngā photodiode paerewa, mā tēnei tikanga whakanui ā-roto ka taea e te APD tePūoko Whakaahuahe iti noa te nui o te mārama, ā, ka hua ake he whakapainga nui i te ōwehenga tohu-ki-haruru.
Mai i te tirohanga mahi,Pūoko Whakaahua APDka taea te kī he rite ki te haurua-ā-ira o ngā ngongo whakarea whakaahua (PMT), ahakoa he rerekē ā rātou mātāpono mahi. Ki te whakatauritea ki ētahi atu hangarau kimi whakaahua hiko pēnei i te PMT, he maha ngā painga o te APD. Kāore i te tino aro ki ngā papa aukume, he nui ake te pai o te matūriki mō ngā tohu mārama whakauru, ā, he iti ake te ngaohiko whakahaere e hiahiatia ana. Heoi anō, ki te whakatauritea ki ngā momo ngongo kē atu, he roa ake te mau o te APD Photodetector me ngā utu iti iho.
Ko te photodiode avalanche he hangarau matua i roto i ngā optoelectronics hou, e hono ana i te āputa i waenga i ngā photodiode tuku iho me ngā ngongo photomultiplier. Ka taea e rātou te whakarato i te whiwhinga ā-roto mā te pānga avalanche, e āhei ai te kite i te tairongo teitei me te pupuri tonu i te pakari me te kiato o ngā taputapu semiconductor. Ko te whanaketanga tonu o te hangarau APD, tae atu ki ngā whanaketanga i roto i ngā rauemi, te hoahoa hanganga, me ngā momo mahi, kei te whakawhānui ake i tana mahi me te whānuitanga tono. Ko ngā putanga hou i roto i ngā hua whānui whiwhi, ngā hoahoa motuhake mō ngā awhe roangaru motuhake, me ngā whakapainga i roto i ngā āhuatanga haruru kei te pana i ngā rohe o ēnei taputapu. I te haere tonu o te rangahau, ka taea e tātou te tumanako atu ki te whakapai ake i te hangarau Photodetector APD, inā koa i roto i ngā wāhanga pēnei i te whakaiti i te haruru, te whakanui ake i te whānui, te whakapai ake i te tairongo, me te whakawhānui ake i te kapinga. Ka haere tonu ēnei whanaketanga ki te hanga i te APD hei wāhanga nui i roto i ngā mara pakeke pēnei i te whakawhitiwhiti kōrero me ngā wāhanga hou pēnei i te hangarau irahiko, ngā pūnaha motuhake, me ngā taputapu pūtaiao matatau.

Ko te photodiode avalanche (APD Photodetector) he whanaketanga nui i roto i te hangarau kimi whatu, e tuku ana i te tairongo teitei me te tikanga whakanui ā-roto, he mea tino whai hua mō ngā tono e hiahia ana kia kitea ngā tohu mārama ngoikore.
