Propitious Escalation in Photocurrent Response from MnZnO3 Thin Films Using Methanol as Sacrificial Agent

Abstract: The thin film of MnZnO3 was prepared from Mn-Zn complex [Mn2Zn2(TFA)8(THF)4]n(1) (where TFA = trifluroactetato and THF = tetrahydrofuran) via aerosol-assisted chemical vapour deposition. The stoichiometry and oxidation of individual elements of the films were determined by x-ray photoelect...
