Although the nominal thickness of Au metal layer was adjusted as small as 1 nm, the resultant microstructure showed the Bruggeman geometry consisting of a networked An clusters. Using the thin film data of the constituent materials An and Si, the optical absorption in the effective medium was calculated, and the effects of composite geometry, particle size, and shape distributions were analyzed. Inhomogeneous broadening of absorption band is thought to be most significant in this BG geometric sample, but the remaining discrepancy between the calculated and the measured absorption may be ascribed to the presence of energy dissipation process due to a finite Schottky barrier built up at the metal-semi conductor junction.
