Morphology-induced spectral modification of self-assembled WS2 pyramids

We characterize the optical response of hollow WS2 pyramids, that exhibit a strongly reduced photoluminescence with respect to horizontally layered WS2. Studying the position dependence of the spectral Raman features reveals local variations in the atomic arrangement.
