Isimo esingaphezulu kanye nokuhlanzeka kwe-substrate ngaphambi kokwelashwa kwe-metal passivation kuzothinta ngqo ikhwalithi ye-passivation layer.Ingaphezulu le-substrate ngokuvamile limbozwa ungqimba lwe-oxide, ungqimba lwe-adsorption, kanye nokungcola okunamathelayo okufana nowoyela nokugqwala.Uma lezi zingakwazi ukususwa ngempumelelo, kuzothinta ngokuqondile amandla okubopha phakathi kongqimba lwe-passivation kanye ne-substrate, kanye nosayizi wekristalu, ukuminyana, umbala wokubukeka, nokushelela kongqimba lwe-passivation.Lokhu kungase kubangele ukukhubazeka okufana nokugwedla, ukuxebuka, noma ukubhakuza kungqimba lwe-passivation, ukuvimbela ukwakheka kongqimba olubushelelezi nolukhanyayo lwe-passivation olunamathela kahle ku-substrate.Ukuthola indawo ehlanzekile esetshenzwe ngaphambilini ngokwelashwa kwangaphambili okungaphezulu kuyimfuneko yokwakha izendlalelo ezihlukahlukene zokudlula eziboshwe ngokuqinile ku-substrate.
