Abstract: Aluminium (Al) - doped zinc oxide (ZnO) nanorods with different weight percent (wt%) of polyethylene glycol (PEG) has been deposited on glass substrate. The concentrations of PEG have been varied from 0 wt %, 15 wt % and 30 wt %. The percentage weight of the PEG is the ratio between PEG mass to the hexamethyltetramine (HMT) and zinc nitrate hexahydrate (Zn (NO3).6H2O) mass. The structural properties of the samples have been characterized using field emission scanning electron microscopy (FESEM) and x-ray diffraction (XRD) and electrical properties has been characterized using current voltage (I-V) measurement. The analyses showed that PEG addition have reduced the crystallinity and conductivity of the samples.

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.
