Optical Properties of Semiconducting Pyrite Deposited by Aerosol Assisted Chemical Vapour Deposition (AACVD) Method

Abstract

Semiconducting pyrites were successfully deposited on glass substrates from Diethyldithiocarbamato iron (III) complex (single source precursor) using aerosol assisted chemical vapour deposition (AACVD) method. Structural analysis of the films shows that pure pyrite was deposited at 300^oC whereas mixture of pyrite and marcasite was deposited at 350^oC, 400^oC and 450^oC. The concentration of the precursor and deposition time has no visible effect on the structure of the deposited films. Optical analyses of the films show that pure pyrite has higher optical absorbance compared to impure pyrite. The concentration of the precursor and deposited time has significant effect on the optical properties of the deposited films.
