Structural characterization of WS₂ flakes by Photoluminescence and ultra-low frequency Raman spectroscopy on a unique multimode platform

2D materials combine the strong covalent in-plane bonding with weak van der Waals (vdW) out-of-plane interactions. These materials exhibit remarkable thermoelectric, conductive, superconductive, optical, and photovoltaic characteristics, and hold potential for applications in nanoelectronics and optoelectronics devices...
