OPTOELECTRONIC CHARACTERISTICS OF MOS2 THIN FILMS: ABSORPTION AND SCATTERING SPECTRA WITH VARYING LAYER CONFIGURATIONS

Abstract
Abstract - Molybdenum disulfide (MoS2), a two dimensional sheet like transition metal dichalcogenide, has garnered significant interest due to its distinct optical and electronic characteristics. In this study, the optoelectronic properties were investigated with respect to absorption and scattering spectra of MoS2 thin films with varying layer thicknesses. Our modeling approach involves finite element method based simulation software to design MoS2 doped poly(methyl methacrylate) (PMMA) thin film nano-composite array deposited on Aluminum doped Zinc Oxide (AZO) coated quartz substrate. The results demonstrate significant shifts in the absorption and scattering spectra, and notable contrast in the absorption coefficients of monolayer and multiple layers (up to 13 layers) MoS2 nanosheets, predicting an enhanced fluorescence spectra in the subsequent wavelengths. The absorption and scattering spectra analysis projected the potential for selective absorption and subsequent fluorescence emission at specific wavelengths, which can be tailored to target specific biomolecules or analytes of interest, in case of bio-imaging applications.
