CZT substrate
wehewehe
ʻO CdZnTe CZT crystal ka epitaxial substrate maikaʻi loa no ka HgCdTe (MCT) infrared detector no ka maikaʻi o kona ʻano aniani a me ka pololei o ka ʻili.

Ka wehewehe CZT substrate
ʻO ka substrate CZT, i ʻike ʻia ʻo cadmium zinc telluride substrate, he substrate semiconductor i hana ʻia me kahi mea semiconductor pūhui i kapa ʻia ʻo cadmium zinc telluride (CdZnTe a i ʻole CZT).ʻO CZT kahi mea kiʻekiʻe atomic helu pololei bandgap mea kūpono no nā ʻano noi like ʻole ma ke kahua o ka X-ray a me ka ʻike ʻana i ka gamma-ray.
Loaʻa i nā substrates CZT kahi bandgap ākea a ʻike ʻia no ko lākou hoʻonā ʻana i ka ikehu maikaʻi loa, ka ʻike kiʻekiʻe kiʻekiʻe, a me ka hiki ke hana ma ka lumi wela.Hana kēia mau waiwai i nā substrates CZT i kūpono no ka hana ʻana i nā mea ʻike radiation, ʻoi aku hoʻi no ke kiʻi X-ray, lāʻau nuklea, palekana homeland, a me nā noi astrophysics.
I nā substrate CZT, hiki ke hoʻololi ʻia ka ratio o ka cadmium (Cd) i ka zinc (Zn), e hiki ai ke hoʻololi i nā waiwai waiwai.Ma ka hoʻopaʻa ʻana i kēia ratio, hiki ke hoʻopili ʻia ka bandgap a me ka haku mele ʻana o CZT i nā koi kikoʻī.Hāʻawi kēia ʻano hoʻololi i ka hana i hoʻonui ʻia a me ka versatility no nā noi ʻike radiation.
No ka hana ʻana i nā substrate CZT, ulu maʻamau nā mea CZT me ka hoʻohana ʻana i nā ʻano like ʻole, me ka ulu ʻana o Bridgman vertical, ke ʻano hoʻomehana hoʻoneʻe, ka ulu ʻana o Bridgman kiʻekiʻe, a i ʻole nā ala lawe moku.Hana ʻia nā kaʻina hana ma hope o ka ulu ʻana e like me ka annealing a me ka polishing no ka hoʻomaikaʻi ʻana i ka maikaʻi aniani a me ka pau ʻana o ka ʻili o ka substrate CZT.
Ua hoʻohana nui ʻia nā substrate CZT i ka hoʻomohala ʻana i nā mea ʻike radiation, e like me nā mea ʻike i hoʻokumu ʻia e CZT no nā ʻōnaehana kiʻi X-ray a me ka gamma-ray, nā spectrometers no ka nānā ʻana i nā mea, a me nā mea ʻike radiation no nā kumu nānā palekana.ʻO kā lākou ʻike kiʻekiʻe kiʻekiʻe a me ka hoʻonā ʻana o ka ikehu e lilo lākou i mau mea waiwai no ka hoʻāʻo ʻole ʻana, ke kiʻi lāʻau lapaʻau, a me nā noi spectroscopy.
