Ibisobanuro bya CZT
CZT substrate, izwi kandi nka cadmium zinc telluride substrate, ni insimburangingo ya semiconductor ikozwe mu bikoresho bivangavanze byitwa cadmium zinc telluride (CdZnTe cyangwa CZT).CZT numubare munini wa atomic numubare wibikoresho bikwiranye nibisabwa bitandukanye murwego rwa X-ray na gamma-ray.
CZT substrates ifite umurongo mugari kandi izwiho gukemura neza kwingufu, gukora neza, hamwe nubushobozi bwo gukora mubushyuhe bwicyumba.Iyi miterere ituma CZT substrate nziza cyane mugukora ibyuma bifata imirasire, cyane cyane kumashusho ya X-ray, ubuvuzi bwa kirimbuzi, umutekano wigihugu, hamwe nubumenyi bwa astrofizike.
Muri CZT substrates, igipimo cya kadmium (Cd) na zinc (Zn) kirashobora gutandukana, bigatuma habaho guhuza ibintu bifatika.Muguhuza iki kigereranyo, bande hamwe nibigize CZT birashobora guhuzwa nibisabwa ibikoresho byihariye.Ihindagurika ryimiterere ritanga imikorere yongerewe imbaraga hamwe nuburyo butandukanye bwo gukoresha imirasire.
Guhimba insimburangingo ya CZT, ibikoresho bya CZT mubisanzwe bihingwa hakoreshejwe uburyo butandukanye, harimo gukura kwa vertical Bridgman, uburyo bwo gushyushya ibintu, umuvuduko ukabije wa Bridgman, cyangwa uburyo bwo gutwara imyuka.Nyuma yo gukura nka annealing na polishing mubisanzwe bikorwa kugirango tunoze ubuziranenge bwa kirisiti hamwe nubuso bwa CZT substrate.
CZT insimburangingo yakoreshejwe cyane mugutezimbere ibyuma bifata imirasire, nka sensor ya CZT ya sisitemu ya X-ray na sisitemu yo gufata amashusho ya gamma-ray, spekrometrike yo gusesengura ibintu, hamwe nubushakashatsi bwimirasire hagamijwe kugenzura umutekano.Ubushobozi bwabo bwo gutahura no gukemura ingufu bituma bakora ibikoresho byingirakamaro mugupima kutangiza, gufata amashusho yubuvuzi, hamwe na progaramu ya spekitroscopi.
