The single crystals of Cu 2 ZnSnS 4 (CZTS) are grown by direct vapor transport technique. The analysis of X-ray from energy dispersion confirmed that the as-grown single crystals are near stoichiometric. The analysis of the as-grown CZTS single crystals by diffraction of X-ray (XRD) showed the crystal possess tetragonal structure having lattice parameters; a = b = 5.42 Å, c = 10.84 Å and α = β = γ = 90º. The Raman spectroscopy showed the presence of a single peak at ~ 331 cm −1 matching with reported CZTS line. The XRD and Raman analysis confirmed the CZTS phase of the as-grown single crystals. The thermal analysis of the as-grown CZTS single crystals is performed by simultaneously recording the thermogravimetric, differential thermogravimetric and differential thermal analysis curves. The kinetic parameters are derived by non-mechanistic Kissinger method using data of the thermocurves. The single crystals growth and varied characterization results on the grown CZTS crystals are thoroughly discussed.
