Qeexida Substrate-ka CZT
Substrate-ka CZT, oo sidoo kale loo yaqaan substrate cadmium zinc telluride, waa substrate semiconductor oo ka samaysan walxo semiconductor ah oo la yiraahdo cadmium zinc telluride (CdZnTe ama CZT).CZT waa qalab sare oo nambarka atomiga ah oo toos ah oo ku habboon codsiyada kala duwan ee goobta raajada iyo ogaanshaha gamma-ray.
Substrate-yada CZT waxay leeyihiin faashad ballaaran waxaana lagu yaqaanaa xallinta tamartooda aadka u fiican, wax ku oolnimada sare ee ogaanshaha, iyo awoodda ay ugu shaqeeyaan heerkulka qolka.Guryahaani waxay ka dhigaan substrate-ka CZT mid ku habboon soo saarista qalabka wax sheegta shucaaca, gaar ahaan sawirka raajada, daawada nukliyeerka, amniga dalka, iyo codsiyada astrophysics-ka.
Qaybaha CZT, saamiga cadmium (Cd) iyo zinc (Zn) waa la kala duwanaan karaa, taas oo awood u siinaysa hagaajinta sifooyinka alaabta.Marka la hagaajiyo saamigan, farqiga bandowga iyo ka kooban yahay CZT waxaa lagu saleyn karaa shuruudaha qalabka gaarka ah.Dabacsanaanta ka kooban waxay bixisaa waxqabad la wanaajiyey iyo kala duwanaansho codsiyada ogaanshaha shucaaca.
Si loo sameeyo substrates CZT, alaabta CZT waxaa sida caadiga ah lagu koray iyadoo la isticmaalayo habab kala duwan, oo ay ku jiraan koritaanka Bridgman toosan, habka kuleyliyaha dhaqaaqa, koritaanka Bridgman-cadaadiska sare, ama hababka gaadiidka uumiga.Nidaamyada korriinka ka dib sida nadiifinta iyo nadiifinta ayaa badanaa la sameeyaa si loo hagaajiyo tayada crystal iyo dhammaystirka dusha sare ee CZT.
Substrate-ka CZT ayaa si weyn loogu isticmaalay horumarinta shucaac-sheegayaasha, sida dareemayaasha ku salaysan CZT ee raajada iyo nidaamyada sawirka gamma-ray, spectrometers ee falanqaynta walxaha, iyo ogaanshaha shucaaca ee ujeedooyinka kormeerka amniga.Waxtarkooda ogaanshaha sare iyo xallinta tamarta ayaa ka dhigaya qalab qiimo leh oo loogu talagalay baaritaanka aan burburin, sawirka caafimaadka, iyo codsiyada spectroscopy.
