ABSTRACT = {This work, pulse laser deposition technique was employee to synthesize Cu2ZnSnS4 (CZTS) thin films 
with different lasing energy (500, 600, 700, 800, 900 mJ). Through using different characterization technique to study 
structural, optical and gas sensing properties. the use of X-ray diffraction, the samples have polycrystalline with cubic 
structure. The EDX examination showed that the sample contains a suitable amount of Zn, Sn, Cu, and S atoms to 
form CZTS. UV-VIS measurement indicates that the synthesis of thin films employing a lower laser energy result in a 
drop in deposit sample thickness, which in turn reduces absorption and raises transmission. The electrical characteristics
 of CZTS thin films reveal that the mobility was decreased at 900 mJ, while the resistivity and carrier concentration
 were improved. The tested devices’ gas response to ammonia (NH<sub>3</sub>) and nitrogen dioxide (NO<sub>2</sub>) gases at varying
 operation temperatures was conducted. The results showed that the sample had a sensitivity of up to 37.57% at 
200°C for NH<sub>3</sub> gas, while the sample had a sensitivity of up to 52% at 300°C for NO<sub>2</sub> gas.},
