Nkọwa mkpụrụ okwu CZT
Mkpụrụ CZT, nke a makwaara dị ka mkpụrụ osisi cadmium zinc telluride, bụ mkpụrụ nke semiconductor mere nke ihe mejupụtara semiconductor ihe akpọrọ cadmium zinc telluride (CdZnTe ma ọ bụ CZT).CZT bụ ọnụọgụ atọ dị elu nke bandgap nke dabara adaba maka ngwa dị iche iche na mpaghara X-ray na nchọpụta gamma-ray.
Ihe ntinye CZT nwere nnukwu bandgap ma mara ya maka mkpebi ike ha dị mma, nchọpụta dị elu, na ike ịrụ ọrụ na okpomọkụ.Ngwongwo ndị a na-eme ka ihe CZT dị mma maka imepụta ihe nchọpụta radieshon, ọkachasị maka onyonyo X-ray, ọgwụ nuklia, nchekwa ala nna na ngwa astrophysics.
Na mkpụrụ nke CZT, oke cadmium (Cd) na zinc (Zn) nwere ike ịdị iche iche, na-eme ka ikike nke ihe onwunwe dị iche iche nwee ike ịdị iche iche.Site n'imezigharị oke a, enwere ike ịhazi bandgap na ngwakọta nke CZT dabere na ihe ngwaọrụ chọrọ.Mgbanwe nke ihe mejupụtara a na-enye arụmarụ ọrụ emelitere yana ngbanwe maka ngwa nchọpụta radieshon.
Iji mepụta mkpụrụ CZT, a na-eji ụzọ dị iche iche na-eto ihe CZT, gụnyere uto Bridgman kwụ ọtọ, usoro ikpo ọkụ na-emegharị ahụ, uto Bridgman dị elu, ma ọ bụ ụzọ mbufe vepo.A na-arụkarị usoro n'eto eto dị ka ntanye na polishing iji melite ogo kristal na imecha elu nke mkpụrụ CZT.
A na-eji ihe CZT eme ihe n'ọtụtụ ebe na mmepe nke ihe nchọpụta radieshon, dị ka CZT dabeere sensọ maka X-ray na gamma-ray imaging sistemu, spectrometers maka nyocha ihe, na radieshon nchọpụta maka nche nche.Nchọpụta ha dị elu na mkpebi ike na-eme ka ha bụrụ ngwaọrụ bara uru maka nnwale na-adịghị emebi emebi, onyonyo ahụike na ngwa spectroscopy.
