    Identification of individual and few layers of WS2 using Raman Spectroscopy

    The Raman scattering of single- and few-layered WS2 is studied as a function of the number of S-W-S layers and the excitation wavelength in the visible range (488, 514 and 647 nm). For the three excitation wavele...

    Nitrogen-doped graphene: beyond single substitution and enhanced molecular sensing

    Graphene is a two-dimensional network in which sp2-hybridized carbon atoms are arranged in two different triangular sub-lattices (A and B). By incorporating nitrogen atoms into graphene, its physico-chemical prop...
