Sabbin ci gaban fasaha naPhotodiodes na dusar ƙanƙara

Hasken walƙiya na walƙiya yana wakiltar babbar fasaha a cikin fasahar zamani ta optoelectronics, tana cike gibin da ke tsakanin fasahar gargajiya.na'urorin photodiodesda kuma bututun photomultiplier. Suna iya samar da riba ta ciki ta hanyar tasirin zaftarewar ƙasa, ta haka ne ake samun ganowa mai ƙarfi yayin da ake kiyaye ƙarfi da ƙanƙantar na'urorin semiconductor.

Ci gaba da ci gabaMai gano Hoto na APDFasaha, gami da ci gaba a cikin kayan aiki, ƙirar tsari da yanayin aiki, tana ci gaba da faɗaɗa ayyukanta da iyakokin aikace-aikacenta. Sabbin ci gaba a cikin samfuran bandwidth na riba, ƙira na ƙwararru don takamaiman kewayon tsayin tsayi, da haɓakawa a cikin halayen hayaniya suna tura iyakokin yiwuwar waɗannan na'urori.

Sabbin ci gaba a cikin APDMai gano hotofasahar ta haɗa da:

Samfurin bandwidth mai matuƙar riba: Masu bincike sun sami na'urar gano hoto ta germanium/silicon APD mai ƙarfin gain bandwidth fiye da THZ 1. An cimma wannan nasara ta hanyar daidaita rarraba filin lantarki daidai da kuma ƙirƙirar tasirin resonance yayin aikin zaftarewar ƙasa.

2. Ingantaccen ganowa daga hasken rana: Sabuwar ƙirar shingen unipolar tana nuna karuwar ambaliyar ruwa har zuwa 5.9 × 10^5 da kuma ikon ganowa na 2.33 × 10^16 Jones a cikin ultraviolet APD mai matakin wafer.

3. Ingantaccen sarrafa wutar lantarki mai lalacewa: Sabbin hanyoyin sarrafa wutar lantarki mai lalacewa sun haɗa da haɗa na'urar shaƙar watsawa da aka samar a lokaci guda tare da yankin na'urar APD. Waɗannan ci gaba suna ci gaba da tura iyakokin damar fasahar APD, suna tallafawa sabbin aikace-aikace da haɓaka aikin waɗanda ke akwai.

Tare da ci gaban bincike, za mu iya tsammanin ƙarin ci gaba na fasahar gano hotuna ta APD, musamman a fannoni kamar rage hayaniya, ƙaruwar bandwidth, haɓaka hankali da faɗaɗa ɗaukar hoto. Waɗannan ci gaban za su ci gaba da sanya APD ta zama muhimmin sashi a fannoni masu tasowa kamar sadarwa da fannoni masu tasowa kamar fasahar kwantum, tsarin cin gashin kai da kayan aikin kimiyya na zamani.
