Abstract: CuO is a p-type semiconducting material with room temperature band gap energy nearly at 1.4 eV for the bulk systems. Here, we present a simple one-pot chemical bath deposition of CuO thin films with nanorod-like crystallites and excellent uniformity of the surface, from an alkaline solution of Cu²⁺ ions. Structural characterisations of the films were carried out by studying XRD patterns and FESEM, EDX and AFM analyses. Broad FWHM of the XRD peaks indicates the formation of nanocrystals. Nanorod-like grain growth along c-axis is evident from the FESEM image. Average diameter of the nanorods was found to be ∼40 nm. Optical absorption spectrum (UV-VIS) of the films showed a blue shift in the band gap energy to ~2.0 eV, due to quantum confinement effect showed by the nanocrystals. Various electrical measurements were also carried out.
