Ma'anar Substrate CZT
CZT substrate, wanda kuma aka sani da cadmium zinc telluride substrate, wani yanki ne na semiconductor wanda aka yi da wani abu mai haɗaɗɗiyar fili wanda ake kira cadmium zinc telluride (CdZnTe ko CZT).CZT babban lambar atom ɗin kai tsaye kayan bandgap wanda ya dace da aikace-aikace iri-iri a fagen X-ray da gano gamma-ray.
CZT substrates suna da faffadan bandeji kuma an san su da kyakkyawan ƙudurin makamashi, ingantaccen ganowa, da ikon yin aiki a cikin ɗaki.Waɗannan kaddarorin sun sa kayan aikin CZT ya dace don kera na'urorin gano radiation, musamman don hoton X-ray, maganin nukiliya, tsaron gida, da aikace-aikacen astrophysics.
A cikin ma'auni na CZT, rabon cadmium (Cd) zuwa zinc (Zn) na iya bambanta, yana ba da damar tunability na kayan abu.Ta hanyar daidaita wannan rabo, bandgap da abun da ke ciki na CZT za a iya keɓanta da takamaiman buƙatun na'urar.Wannan sassauƙan abun ciki yana ba da ingantaccen aiki da juzu'i don aikace-aikacen gano radiation.
Don ƙirƙira abubuwan CZT, kayan CZT galibi ana girma ta amfani da hanyoyi daban-daban, gami da haɓaka Bridgman a tsaye, hanyar dumama motsi, haɓakar Bridgman mai ƙarfi, ko hanyoyin jigilar tururi.Bayan-girma matakai kamar annealing da polishing yawanci yi don inganta crystal ingancin da surface gama na CZT substrate.
An yi amfani da ma'auni na CZT sosai a cikin haɓaka na'urorin gano hasken wuta, irin su na'urori masu auna firikwensin CZT don X-ray da tsarin hoton gamma-ray, na'urori don nazarin kayan aiki, da masu gano radiation don dalilai na tsaro.Babban aikin gano su da ƙudurin kuzari ya sa su zama kayan aiki masu mahimmanci don gwaji marasa lalacewa, hoton likitanci, da aikace-aikacen spectroscopy.
