Gawo la CZT
Kufotokozera
CdZnTe CZT crystal ndiye gawo labwino kwambiri la epitaxial la HgCdTe (MCT) infrared detector chifukwa cha mtundu wake wa kristalo komanso kulondola kwapamtunda.

Tanthauzo la Gawo la CZT
CZT gawo lapansi, lomwe limadziwikanso kuti cadmium zinc telluride substrate, ndi gawo lapansi la semiconductor lopangidwa ndi zinthu zomwe zimatchedwa cadmium zinc telluride (CdZnTe kapena CZT).CZT ndi nambala ya atomiki yolunjika ya bandgap yomwe imayenera kugwiritsidwa ntchito mosiyanasiyana pankhani ya X-ray ndi kuzindikira kwa gamma-ray.
Magawo a CZT ali ndi bandgap yotakata ndipo amadziwika chifukwa cha mphamvu zake zabwino kwambiri, kuzindikira kwakukulu, komanso kuthekera kogwira ntchito kutentha kwachipinda.Katunduwa amapangitsa magawo a CZT kukhala abwino popanga zida zowunikira ma radiation, makamaka pojambula zithunzi za X-ray, mankhwala a nyukiliya, chitetezo chakudziko, komanso kugwiritsa ntchito zakuthambo.
Mu magawo a CZT, chiŵerengero cha cadmium (Cd) mpaka zinki (Zn) chikhoza kukhala chosiyana, kupangitsa kuti zinthu zikhale bwino.Pakukonza chiŵerengerochi, bandeji ndi kapangidwe ka CZT zitha kupangidwa mogwirizana ndi zofunikira za chipangizocho.Kusinthasintha kophatikizikaku kumapereka magwiridwe antchito komanso kusinthika kwazinthu zowunikira ma radiation.
Kuti apange magawo a CZT, zida za CZT zimabzalidwa pogwiritsa ntchito njira zosiyanasiyana, kuphatikiza kukula kwa Bridgman, njira yotenthetsera, kukula kwa Bridgman, kapena njira zoyendera mpweya.Njira zokulira pambuyo pakukula monga kutseketsa ndi kupukuta nthawi zambiri zimachitidwa kuti apititse patsogolo mawonekedwe a kristalo ndi kutha kwa gawo lapansi la CZT.
Magawo a CZT akhala akugwiritsidwa ntchito kwambiri popanga zida zowunikira ma radiation, monga masensa a CZT a makina oyerekeza a X-ray ndi ma gamma-ray, ma spectrometer owunikira zinthu, ndi zowunikira ma radiation kuti aziwunika chitetezo.Kuzindikira kwawo kwakukulu komanso kuwongolera mphamvu kumawapangitsa kukhala zida zofunika pakuyesa kosawononga, kujambula kwachipatala, komanso kugwiritsa ntchito ma spectroscopy.
