TSHIAB HIG HUV Photodetector

Tshiabsiab rhiab photodetector

Tsis ntev los no, pab pawg tshawb fawb ntawm Suav Academy (CAS) raws li polycrystalline gallium-Rich Tsim Kev Tsim Nyog rau cov kev paub zoo thiab muaj kev teb siab nrawm nrawmphotodetectorLos ntawm Coupling interface pyroelectric thiab photoconductivity cuam tshuam, thiab cov kev tshawb fawb muaj feem tau luam tawm hauv cov ntaub ntawv siab. High-zogPhotoelectric Detectors(Rau tob ultraviolet (DUV) rau x-ray bands) yog qhov tseem ceeb nyob rau hauv ntau hom teb, suav nrog kev nyab xeeb hauv teb chaws, tshuaj, thiab kev tshawb fawb txog kev lag luam hauv teb chaws, tshuaj thiab kev tshawb fawb.

Txawm li cas los xij, cov ntaub ntawv semiconductor xws li Si thiab α-SE muaj cov teeb meem loj tam sim no thiab qis vas nqus coefficient, uas yog qhov nyuaj kom tau raws li cov kev xav tau ntawm cov kev kawm tau zoo. Nyob rau hauv kev sib piv, dav-band gap (WBG) semiconductor gallium oxide cov ntaub ntawv qhia tau zoo rau kev kuaj lub zog photicelectric zoo. Txawm li cas los xij, vim yog qhov sib zog ntawm cov khoom sib sib zog nqus ntawm cov khoom siv sab nraud thiab cov qauv zoo rau cov qauv siv hluav taws xob raws li cov qauv hluav taws xob raws li cov laj thawj dav. Txhawm rau daws cov kev cov nyom no, pab pawg tshawb fawb hauv Suav teb tau tsim ib qho Pyroeltric phem phiboconductive diode (PPD) raws li PGR-GAOX thawj zaug. Los ntawm txuas lub interface pyroelectric nyhuv nrog lub photoconduction cov txiaj ntsig, kev kuaj pom qhov ua tau zoo txhim kho. PPD qhia txog qhov siab dua rau ob qho tib si Duv thiab X-Rays, nrog rau cov lus teb-1 / CM2, ntau dua 100 npaug dua li yav dhau los kuaj tau ua cov khoom zoo sib xws. Ib qho ntxiv, lub interface pyroelectric cov nyhuv tshwm sim los ntawm lub polar symmetry ntawm thaj av PGR-Gaox denpletion tuaj yeem nce cov lus teb ceev ntawm lub ntes ntawm 105 zaug rau 0.1ms. Piv rau cov duab photional, tus kheej siv tus kheej ppds tsim cov tsheb siab dua vim yog pyroeltric teb thaum lub teeb hloov.

Tsis tas li ntawd, PPD tuaj yeem ua haujlwm hauv hom kev tsis ncaj ncees, qhov twg qhov nce siab ntawm Bias voltage, thiab ultra-high nce tuaj yeem ua tiav los ntawm kev ua kom muaj kev cuam tshuam los ntawm kev cuam tshuam qhov ntsuas hluav taws xob. PPD muaj cov ntawv thov zoo nyob hauv kev siv hluav taws xob tsawg thiab cov siab siab cov ntsiab lus txhim kho tshuab. Txoj haujlwm no tsis yog ua pov thawj tias Gaox yog ib qho kev cog lusSiab Zog PhodetectorCov khoom siv, tab sis kuj muab lub tswv yim tshiab rau kev paub txog cov kev ua tau zoo siab siab lub zog photodetectors.
