CZT sobusitireti Definition
Sobusitireti CZT, ti a tun mọ ni sobusitireti cadmium zinc telluride, jẹ sobusitireti semikondokito ti a ṣe ti ohun elo semikondokito agbo ti a pe ni cadmium zinc telluride (CdZnTe tabi CZT).CZT jẹ nọmba atomiki giga taara ohun elo bandgap ti o dara fun ọpọlọpọ awọn ohun elo ni aaye X-ray ati wiwa gamma-ray.
Awọn sobusitireti CZT ni bandgap jakejado ati pe wọn mọ fun ipinnu agbara to dara julọ, ṣiṣe wiwa giga, ati agbara lati ṣiṣẹ ni iwọn otutu yara.Awọn ohun-ini wọnyi jẹ ki awọn sobusitireti CZT jẹ apẹrẹ fun iṣelọpọ awọn aṣawari itankalẹ, pataki fun aworan X-ray, oogun iparun, aabo ile-ile, ati awọn ohun elo astrophysics.
Ninu awọn sobusitireti CZT, ipin ti cadmium (Cd) si zinc (Zn) le jẹ oriṣiriṣi, ti n mu agbara awọn ohun-ini ohun elo ṣiṣẹ.Nipa yiyi ipin yii, bandgap ati akopọ ti CZT le ṣe deede si awọn ibeere ẹrọ kan pato.Irọrun akojọpọ yii n pese iṣẹ imudara ati iṣiṣẹpọ fun awọn ohun elo wiwa itankalẹ.
Lati ṣe awọn sobusitireti CZT, awọn ohun elo CZT jẹ igbagbogbo dagba ni lilo awọn ọna pupọ, pẹlu inaro idagbasoke Bridgman, ọna igbona gbigbe, idagbasoke Bridgman giga-giga, tabi awọn ọna gbigbe oru.Awọn ilana idagbasoke-lẹhin gẹgẹbi annealing ati didan ni a maa n ṣe lati mu ilọsiwaju didara gara ati ipari dada ti sobusitireti CZT.
Awọn sobusitireti CZT ti ni lilo pupọ ni idagbasoke ti awọn aṣawari itankalẹ, gẹgẹbi awọn sensọ orisun CZT fun X-ray ati awọn eto aworan gamma-ray, awọn iwoye fun itupalẹ ohun elo, ati awọn aṣawari itankalẹ fun awọn idi ayewo aabo.Ṣiṣe wiwa giga wọn ati ipinnu agbara jẹ ki wọn ṣe awọn irinṣẹ to niyelori fun idanwo aibikita, aworan iṣoogun, ati awọn ohun elo iwoye.
