Single crystals of MoTe2 grown by chemical vapour transport technique were used here. X-ray diffraction technique reveals that the MoTe2 crystals belong to hexagonal crystal structure. The optical response of these crystals has been obtained by UV-VIS-NIR spectroscopy. The transmittance of MoTe2 crystal has been used to calculate the refractive index (n), the extinction co-efficient (k) and both real(∊r) and imaginary (∊i) components of the dielectric constant as function of wavelength at room temperature. Thermogravimetric analysis (TGA) and differential thermal analysis (DTA) were carried out for MoTe2 single crystals. The detailed surface microtopographic studies of these crystals by means of optical microscopy showed that the layer mechanism is predominant during growth. Even spiral growth is equally common on the as-grown faces.
