The structure of niobium-doped MoSe2 and WSe2
Polycrystalline niobium-doped molybdenum and tungsten diselenides were synthesized in silica tubes sealed under secondary vacuum. They were characterized by scanning electron microscopy, electron diffraction, X-ray diffraction, chemical composition and EDX analyses. The morphology of niobium-doped molybdenum solid solutions was shown to depend strongly on the conditions of synthesis, whereas the structural characterization did not.
