Transition metal dichalcogenides (TMDs) materials such as molybdenum disulfides MoS₂ are one of the most promising semiconductors for next-generation photovoltaic solar cells due to its great excitonic recombination property and high carrier mobility. TMDs materials with nanostructures have been reported to have the optical properties highly dependent on their dimensions such as their size and shapes, therefore, nano-scale characterization is a demand for understanding. In this study, we experimentally map localized field in a triangular MoS₂ nanoflake with nanometer spatial resolution by cathodoluminescence technique and identify individual existent modes analyzed by a spectral deconvolution method
