Abstract

original image

Inorganic nanocrystals: The structures of the compounds [(PbSe)1.00]m(MoSe2)n and [(PbSe)0.99]m(WSe2)n (m1 and n≤5) were investigated using X-ray diffraction and scanning transmission electron microscopy, which revealed a pairing distortion of the PbSe component that is dependent on m, the thickness of the PbSe layers, but independent of n, the thickness of the dichalcogenide.
