| Popis: | MoSe 2 single crystals were grown by chemical vapor transport using TeCl 4 as transport agents in the temperature gradient 1020–980 °C. They were characterized by scanning electron microscopy (SEM), optical microscopy, image analysis coupled with SEM, microanalysis by SEM-EDX, X-ray fluorescence, inductively coupled plasma (ICP), X-ray photoelectron spectroscopy (XPS) and electrical conductivity. The characterizations showed that single crystals are perfectly homogeneous, stoichiometric and have very few defects and clean surfaces with areas in the range of 35–100 mm 2 . Single crystals grown by TeCl 4 showed a high electrical conductivity. Their properties were highly dependent on the quality of the polycrystalline powders used for the growth. |
