In this work, we report the synthesis of Cu₂ZnSnS₄ (CZTS)  single crystal by cooling a molten stoichiometric of Cu, Zn, Sn and S elements. Weighed stoichiometric proportions were charged into a 200 mm length and 14mm diameter quartz tube sealed off under 5x10^-6 Torr, placed in a horizontal furnace then heated up gradually. Secondary phases between Cu, Zn, Sn with S were formed by keeping the tube in below temperature range (200-700 °C) for 24-48h to reduce the vapor pressure and avoid any explosion in high temperature [1-3]. To ensure homogeneous mixing of the melt, the tube was kept at 1100 °C for 24-48 h. The furnace was then cooled down freely reaching room temperature. Removed from the quartz tube, the CZTS ingot was about 25 mm. The ingot chemical composition analyses determined by Energy Dispersive Spectroscopy (EDS) were found to be nearly stoichiometric. The crystal bulk structure was analyzed by using powder X-Ray Diffraction (XRD), the diffraction peaks indicate a remarkable crystalline nature with preferred orientations of (112) plan. We carried out the Raman measurements which indicate that crystal adopts a kesterite structure without secondary phases. The carrier
