Abstract

Mono- and few-layer MoS₂ were studied by three-dimensional electron diffraction (3D ED) showing distinctly different symmetry for crystals consisting of odd and even number of layers. Experimentally obtained intensity distributions along the relrods match qualitatively kinematically simulated data. Our findings allow to differentiate unambiguously between 1-, 2-, 3- 4- and 5-layers MoS₂ crystals.
