    Cov Kev Kawm Siv Tau

    Daim ntawv xeem

    Silicon yog mono siv lead ua feem ntau siv nyob rau hauv semi-neeg xyuas pib thiab yog tsis-haum ntawm 1.2μm rau 6μm IR cheeb tsam. Nws yog siv ntawm no ua qhov khoom siv kho qhov muag rau IR cheeb tsam kev siv.
    Silicon yog siv los ua qhov rooj kho qhov muag feem ntau hauv 3 txog 5 micron band thiab ntxiv rau cov txheej hauv qab rau kev tsim cov ntxaij lim dej optical. Cov thaiv loj ntawm Silicon nrog rau sab ntsej muag kuj yog ua haujlwm raws li neutron cov phiaj xwm hauv Physics sim.
    Silicon yog loj hlob los ntawm Czochralski rub cov txuj ci (CZ) thiab muaj qee cov pa uas ua rau muaj kev nqus ntawm 9 microns. Txhawm rau zam qhov no, Silicon tuaj yeem npaj tau los ntawm Float-Zone (FZ) txheej txheem. Silicon kho qhov muag feem ntau maj mam doped (5 txog 40 ohm cm) rau qhov kev xa xov zoo tshaj 10 microns. Silicon muaj qhov txuas ntxiv ntawm cov kab xev 30 txog 100 microns uas ua tau zoo tsuas yog muaj ntau yam hauv siab heev resistivity uncompensated khoom. Doping feem ntau yog Boron (p-hom) thiab Phosphorus (n-hom).
    Daim ntawv thov:
    • Zoo tshaj rau 1.2 txog 7 μm NIR daim ntawv thov
    • Broadband 3 txog 12 μm los tiv thaiv kev tha xim tiv thaiv
    • Zoo tagnrho rau cov ntawv thov nyhav
    Nta:
    • Cov qhov rais silicon tsis xa tawm ntawm 1µm thaj av lossis qis dua, yog li ntawd nws cov ntawv thov tseem ceeb yog nyob hauv cheeb tsam IR.
    • Vim tias nws cov thermal ua hluav taws xob ntau, nws haum rau siv raws li lub zog siab tsom iav
    Icon Silicon qhov rais muaj qhov ci ntsa iab hlau nto; nws xav txog thiab nqus tab sis tsis kis hauv cov cheeb tsam pom.
    Icon Silicon lub qhov rais tsom mus rau sab saum toj tau ua rau pom qhov ua paug qhov poob ntawm 53%. (ntsuas cov ntaub ntawv 1 lub ntsej muag kho ntawm 27%)
