CZT Substrate Inkcazo
I-substrate ye-CZT, ekwabizwa ngokuba yi-cadmium zinc telluride substrate, yi-semiconductor substrate eyenziwe nge-compound semiconductor material ebizwa ngokuba yi-cadmium zinc telluride (CdZnTe okanye CZT).I-CZT yimathiriyeli ye-athom ephezulu ye-athom ngqo ye-bandgap efanelekileyo kwizicelo ezahlukeneyo kwintsimi ye-X-reyi kunye ne-gamma-ray.
Ii-substrates ze-CZT zinebhendi ebanzi kwaye ziyaziwa ngosombululo lwazo lwamandla olugqwesileyo, ukusebenza kakuhle kokubona, kunye nokukwazi ukusebenza kubushushu begumbi.Ezi zakhiwo zenza i-CZT substrates zibe zilungele ukuvelisa izixhobo zokujonga ukusasazeka kwemitha, ingakumbi kumfanekiso weX-reyi, iyeza lenyukliya, ukhuseleko lwelizwe, kunye nosetyenziso lwe-astrophysics.
Kwii-substrates ze-CZT, umlinganiselo we-cadmium (Cd) ukuya kwi-zinc (Zn) unokuhluka, okwenza kube lula ukulinganisa izinto eziphathekayo.Ngokulungelelanisa lo mlinganiselo, i-bandgap kunye nokwakhiwa kwe-CZT inokulungelelaniswa neemfuno zesixhobo esithile.Oku bhetyebhetye okudityanisiweyo kubonelela ukusebenza okuphuculweyo kunye nokuguquguquka kwezicelo zokubona ukukhanya kwemitha.
Ukwenza i-CZT substrates, imathiriyeli ye-CZT idla ngokukhuliswa kusetyenziswa iindlela ezahlukeneyo, kubandakanywa ukukhula kweBridgman ngokuthe nkqo, indlela yesifudumezi esishukumayo, ukukhula koxinzelelo oluphezulu lweBridgman, okanye iindlela zokuthutha umphunga.Iinkqubo zasemva kokukhula ezifana nokufakwa kunye nokupholisha zidla ngokuqhutyelwa ukuphucula umgangatho wekristale kunye nokugqitywa komphezulu we-substrate ye-CZT.
Ii-substrates ze-CZT zisetyenziswe ngokubanzi kuphuhliso lwezixhobo zokuqaphela ukusasazeka kwemitha, ezifana ne-CZT-based sensors ye-X-reyi kunye ne-gamma-imaging systems, ii-spectrometers zohlalutyo lwezinto, kunye nezixhobo zokujonga ukushisa ngemitha ngeenjongo zokuhlola ukhuseleko.Ukusebenza kwabo okuphezulu kunye nesisombululo samandla kubenza babe zizixhobo ezixabisekileyo zovavanyo olungonakaliyo, umfanekiso wezonyango, kunye nosetyenziso lwe-spectroscopy.
