Abstract
The aim of study was to investigate the carrier transport properties of seed layer assisted nanostructured ZnO thin film. The structural analysis by XRD showed the predominant peak at 34.63° (2θ) corresponding to <002> plane. From the SEM image, it was found that the particles grown vertical nanoparticles on the glass substrate. The optical bandgap of the material was calculated from UV-Visible absorption spectrum which was found as 3.28 eV. The I-V characteristics showed that the film possess semiconducting nature. The electron mobility was determined as 1.60×102cm2/Vs and the resistivity was around 1.99×10−4 Ω.cm and the carrier concentration of the film was 7.54×1020cm−3 by Hall effect measurement. The seed assisted nanostructured film exhibited good electron transport properties which can be applied in many electrical applications like a solar cells, sensors and optoelectronic devices.
