I-PhotoDector entsha ephezulu

-KwanamuhlaI-PhotoDet ephezulu yokuzwela

Muva nje, iqembu labacwaningi eChina Academy of Sciences (CAS) ngokususelwa ku-polycrystaltine gallium-rich gallium-rich gallium oxide izinto zokwakha (PGR-GAX) okuhlongozwayo okokuqala iqhinga elisha ledizayini lokuzwela okuphezulu nesivinini esikhulu sokuphendulaI-PhotoDETETETETECETETETNgokusebenzisa isikhombimsebenzisi esihlanganisiwe se-pyroelectric kanye nemiphumela ye-photokoductivity, kanye nocwaningo olufanele lwashicilelwa ngezinto ezithuthukisiwe. Amandla aphezuluUkuthola Photoectric(Ngokwe-Ultraviolet (DUV) kuma-X-ray band) kubalulekile ezinkundleni ezahlukahlukene, kufaka phakathi ukuphepha kwezwe, umuthi kanye nesayensi yezimboni.

Kodwa-ke, izinto zokwenziwa zamanje ze-semiconductor ezinjenge-SI ne-α-SE zinezinkinga zokuvuza okukhulu kwamanje kanye ne-X-ray Absorption coeffliction, okunzima ukufeza izidingo zokutholwa kokusebenza okuphezulu. Ngokuphambene nalokho, i-readounder-band gar Gallium oxide izinto ezibonisa amandla amakhulu okuthola isithombe. Kodwa-ke, ngenxa yesicupho esingenakugwenywa esijulile ohlangothini lwezinto ezibonakalayo kanye nokuntuleka kokwakheka okusebenzayo kwisakhiwo sedivayisi, kuyinselele ukuqaphela ukuzwela okuphezulu kanye ne-high rescience ephezulu yamandla we-puton demon deton kususelwa kuma-semiconductors aphezulu we-band photon. Ukubhekana nalezi zinselelo, iqembu labacwaningi eChina lenze i-Pyroelectric PhotoConductive Diode (PPD) ngokususelwa ku-PGR-Gaox okokuqala. Ngokuhlanganisa umphumela we-interface pyroelectric effect nge-Photocoductivity Effect, ukusebenza okutholwayo kuthuthukiswa kakhulu. I-PPD ikhombise ukuzwela okuphezulu kwi-DUV kanye nama-X-Rays, ngamanani okuphendula afinyelela ku-104A / W kanye ne-105μc Ngaphezu kwalokho, umphumela we-interface pyroelectric umphumela obangelwa ukufana kwePolar yesifunda se-PGR-GAOX Delechetion ungangezelela ijubane lokuphendula lomtshina ngezikhathi ezingama-105 kuya ku-0.1ms. Uma kuqhathaniswa nama-PhotoDodione ajwayelekile, i-Mode Ezenzela amandla i-PPDS ikhiqiza izinzuzo eziphakeme ngenxa yamasimu e-Pyroelectric ngesikhathi sokushintsha okukhanyayo.

Ngaphezu kwalokho, i-PPD ingasebenza kwimodi ye-bias, lapho inzuzo incike kakhulu ku-BIAS VOLTAGE, futhi inzuzo ephezulu kakhulu ingatholakala ngokwandisa amandla we-BAS. I-PPD inekhono elihle kakhulu lokusebenza ekusetshenzisweni kwamandla okuphansi kanye nezinhlelo eziphakeme zokukhuthaza ukuthuthukiswa kwezinhlelo. Lo msebenzi awubonakali kuphela ukuthi i-gaox iyathembisaI-PhotoDet ephezulu yamandlaIzinto ezibonakalayo, kepha futhi zinikeza isu elisha lokuthola ukusebenza kwamandla aphezulu okuphezulu kwamandla.
