Improvement sensitivity humidity sensor based on ZnO/SnO2 cubic structure
ZnO nanorod, SnO2 nanoparticle and ZnO/SnO2 cubic structure were prepared using sol-gel immersion method. These three structures had been growth on top sputtered ZnO thin film. The surface morphology of all thin film were characterized using field emission scanning electron microscopy (FESEM) and en...
