Photoluminescence anisotropy in hybrid nanostructures based on gallium phosphide nanowire and 2D transition metal dichalcogenides

Integration of nanophotonic structures having different geometry is a well-established way to promote desired optical effects. This work is aimed at study of the optical properties of a hybrid structure based on a transition metal dichalcogenides (TMDC) thin layer and III-V nanowires. The structures were studied by µ-Raman and µ-photoluminescence spectroscopy at room temperature. We demonstrate experimentally guiding of the TMDC photoluminescence through the individual nanowires and analyze this phenomenon. The results of the work shed a light on new ways for fabrication of integrated optical circuitry components.
