In this study, we aimed to control dimensions of vertically aligned nanorods on zinc oxide (ZnO) seed layer coated glass substrate and to investigate effects of density on gas sensing. To produce ZnO seed layer, Zinc acetate solution was coated by using spin-coater. ZnO nanorods with different density were grown by changing concentration of solution used in hydrothermal process. Hydrothermal process was realized at 90°C for 3h. For investigation gas sensing properties, interdigitated Au electrodes...
