Optical signature of symmetry variations and spin-valley coupling in atomically thin tungsten dichalcogenides

We report systematic optical studies of WS(2) and WSe(2) monolayers and multilayers. The efficiency of second harmonic generation shows a dramatic even-odd oscillation with the number of layers, consistent with the presence (absence) of inversion symmetry in even-layer (odd-layer). Photoluminescence...
