The Role of Counteranions in Solution Deposition of ZnS Thin Films on GaAs.

ABSTRACT: Using 5 commonly employed precursors for Zn²⁺ cations, ZnSO₄, ZnI₂, ZnCl₂, Zn(NO₃)₂, and Zn(CH₃COO)₂, we demonstrate the effect of counterions on ZnS thin film formation. We show that both film nucleation and growth stages are strongly dependent on the Zn²⁺ precursor type. We systematically studied the mechanisms of thin film deposition on GaAs(100), including solution-substrate interactions, Zn²⁺ ion adsorption on the substrate, and nuclei formation as well as stress accumulation during film growth. It was shown that the early stages of film formation play a key role in the subsequent growth kinetics and resulting film quality. X-ray photoelectron spectroscopy, supported by contac
