CZT Substrate txhais
CZT substrate, tseem hu ua cadmium zinc telluride substrate, yog ib tug semiconductor substrate ua los ntawm ib tug compound semiconductor khoom hu ua cadmium zinc telluride (CdZnTe los yog CZT).CZT yog ib tug high atomic tooj ncaj bandgap khoom haum rau ntau yam kev siv nyob rau hauv lub tshav pob ntawm X-ray thiab gamma-ray nrhiav kom tau.
CZT substrates muaj qhov dav bandgap thiab paub txog lawv cov kev daws teeb meem zoo heev, kev ua haujlwm siab nrhiav pom, thiab muaj peev xwm ua haujlwm ntawm chav tsev kub.Cov khoom no ua rau CZT substrates zoo tagnrho rau kev tsim hluav taws xob ntes, tshwj xeeb tshaj yog rau X-ray duab, tshuaj nuclear, kev ruaj ntseg hauv tebchaws, thiab kev siv astrophysics.
Hauv CZT substrates, qhov piv ntawm cadmium (Cd) rau zinc (Zn) tuaj yeem sib txawv, ua kom muaj kev sib haum xeeb ntawm cov khoom siv.Los ntawm kev kho qhov piv txwv no, qhov bandgap thiab cov ntsiab lus ntawm CZT tuaj yeem raug kho raws li cov khoom siv tshwj xeeb.Qhov kev sib xyaw ua ke yooj yim no muab kev ua tau zoo dua qub thiab ntau yam rau kev siv hluav taws xob tshawb pom.
Txhawm rau tsim CZT substrates, cov ntaub ntawv CZT feem ntau yog siv ntau txoj hauv kev, suav nrog txoj kev loj hlob ntawm Bridgman ntsug, txav cov cua sov txoj kev, siab-siab Bridgman kev loj hlob, los yog vapor thauj txoj kev.Cov txheej txheem tom qab kev loj hlob xws li annealing thiab polishing feem ntau yog ua los txhim kho cov siv lead ua zoo thiab nto tiav ntawm CZT substrate.
CZT substrates tau siv dav hauv kev tsim cov khoom siv hluav taws xob, xws li CZT-raws li sensors rau X-ray thiab gamma-ray imaging systems, spectrometers rau cov khoom tsom xam, thiab hluav taws xob detectors rau kev ruaj ntseg soj ntsuam lub hom phiaj.Lawv qhov kev tshawb nrhiav tau zoo thiab lub zog daws teeb meem ua rau lawv cov cuab yeej tseem ceeb rau kev sim tsis muaj kev puas tsuaj, kev kho mob, thiab kev siv spectroscopy.
