Daim Ntawv Thov Cov Ntawv Uas Qhia Txog Tus Neeg Cadmium
- Sep 05, 2017 -

Tellurium Zinc Cadmium, txhais tias CZT. Lub CZT Crystal yog ib qho bandgap-compound semiconductor, thiab qhov nruab nrab ntawm qhov sib txawv ntawm 1092-1295 degrees Celsius raws li tus nqi ntawm Zn ntxiv. Dav siv los ua ib qho chaw nyob hauv chaw thau khoom thiab chaw sov hluav taws xob hauv tsev rau infrared detectors, nws muaj duab zoo nkauj heev thiab muaj peev xwm hloov X-ray thiab gamma-ray photons rau hauv electrons ntawm chav tsev kub, uas yog qhov zoo tshaj plaws semiconductor khoom siv los tsim chav kub X- txoj kab xo thiab gamma-txoj kab hluav taws kom deb li deb. Crystal yog lub semiconductor nkaus xwb uas tuaj yeem ua haujlwm ntawm qhov chaw sov thiab tuaj yeem txhuam 2 lab photons / (s hli) piv rau silicon thiab germanium detectors. Tsis tas li ntawd, lub siv lead ua splitting tus nqi zoo dua li tag nrho cov muaj qhov kho qhov muag iav. Muaj ntau qhov zoo ntawm lub ntsuas tau ua ntau thiab siv ntau dua, xws li kev ruaj ntseg ntawm nuclear, kev saib xyuas, kev tshawb nrhiav astrophysics thiab lwm yam hauj lwm. Hauv kev tshawb fawb ntawm kev tshawb fawb, lub tshuab kuaj pom tau zoo tshaj plaws hauv cheeb tsam lub siab zog physics, piv txwv li, nws tuaj yeem siv rau hauv kev siv zog ntawm cov khoom siv zog. Compound semiconductor detectors yog cov kev sib tw thiab yuav tsum tau ua kom zoo heev hauv kev tshawb fawb particics. Tsis tas li ntawd, lub tshuab kuaj pom muaj ntau daim ntawv thov foreground astronomical physics tshawb nrhiav. Tam sim no, txoj kev tshawb nrhiav ntawm lub ntsuas yog nyob rau ntawm ib qho kev loj hlob sai ntawm cov ntaub ntawv tseem ceeb tshiab pib thaum pib xyoo 1991, thiab vim tias nws muaj peev xwm kawg siab thiab muaj peev xwm ua hauj lwm nyob rau hauv chav tsev kub ntawm cov cwj pwm txawv, tau tshwm sim los ntawm kev lag luam lom zem.
