I-CZT Substrate
Incazelo
Ikristalu ye-CdZnTe CZT iyi-epitaxial substrate engcono kakhulu yomtshina we-infrared we-HgCdTe (MCT) ngenxa yekhwalithi yawo yekristalu enhle kakhulu nokunemba kwendawo.

Incazelo ye-CZT Substrate
I-CZT substrate, eyaziwa nangokuthi i-cadmium zinc telluride substrate, i-semiconductor substrate eyenziwe nge-compound semiconductor material ebizwa nge-cadmium zinc telluride (CdZnTe noma CZT).I-CZT iyinombolo ye-athomu ephezulu ye-bandgap eqondile efanele ukusetshenziswa okuhlukahlukene emkhakheni we-X-ray kanye nokutholwa kwe-gamma-ray.
Ama-substrates e-CZT ane-bandgap ebanzi futhi aziwa ngokulungiswa kwawo okuhle kwamandla, ukusebenza kahle kokutholwa kwawo, kanye nekhono lokusebenza ekamelweni lokushisa.Lezi zakhiwo zenza i-CZT substrates ibe yinhle kakhulu ekwenzeni izithungatha zemisebe, ikakhulukazi i-X-ray imaging, imithi yenuzi, ukuvikeleka kwezwe, kanye nezicelo ze-astrophysics.
Kuma-substrates e-CZT, isilinganiso se-cadmium (Cd) kuya ku-zinc (Zn) singahluka, sivumele ukuhwebelana kwezinto ezibonakalayo.Ngokulungisa lesi silinganiso, i-bandgap nokwakheka kwe-CZT kungenziwa ngendlela efanele izidingo ezithile zedivayisi.Lokhu kuvumelana nezimo kokuqamba kunikeza ukusebenza okuthuthukisiwe kanye nokuguquguquka kwezinhlelo zokusebenza zokuthola imisebe.
Ukuze kwenziwe ama-substrates e-CZT, izinto ze-CZT zivame ukukhuliswa kusetshenziswa izindlela ezihlukahlukene, okuhlanganisa ukukhula kwe-Bridgman okuma mpo, indlela ye-heater enyakazayo, ukukhula kwe-Bridgman enengcindezi ephezulu, noma izindlela zokuthutha umhwamuko.Izinqubo zokukhula kwangemva kokukhula okufana nokucwenga nokupholishwa kuvame ukwenziwa ukuze kuthuthukiswe ikhwalithi yekristalu nokuqedwa kwendawo ye-CZT substrate.
Ama-substrates e-CZT asetshenziswe kabanzi ekwakhiweni kwezinto ezihlola imisebe, njengezinzwa ezisekelwe ku-CZT ze-X-ray kanye nezinhlelo ze-gamma-imaging imaging, ama-spectrometer okuhlaziya izinto ezibonakalayo, kanye nezitholi zemisebe ngezinjongo zokuhlola ukuphepha.Ukusebenza kahle kokutholwa kwazo okuphezulu kanye nokulungiswa kwamandla kuzenza zibe amathuluzi abalulekile okuhlola okungonakali, ukuthwebula izithombe zezokwelapha, nezinhlelo zokusebenza ze-spectroscopy.
