Abstract

Zinc oxide (ZnO) nanorods with different Aluminium (Al) – doping concentration (at%) has been deposited on glass substrate. The concentrations of Al were varied from 0 (undoped), 0.2, 0.8, and 3 at %. Field emission scanning electron microscopy (FESEM) was used to study the structural properties of the samples, UV-vis for absorbance and transmittance coefficient, and current voltage (I-V) measurement for electrical properties. From the results, it is observed that the diameter size of nanorods were reduced upon the increasing of Al-concentration. The I-V measurement showed that the 0.8 at% doping sample produced the highest conductivity.
