Abstract

original image

Inorganic sheets: Graphene-like MoS2 and WS2 were prepared by three different chemical methods. Examination by microscopic techniques revealed that they consist of one or a few layers (see depicted TEM image of WS2 layers), and an atomic-resolution TEM image showed that layered MoS2 has a hexagonal arrangement of Mo and S atoms (see inset).
