Copper nanofilms are extensively used in the field of material science research. Nanoparticles and nanostructures of copper have various utilities in the field of photocatalytic and sensor applications. The transition metal nanoparticles and nanostructures supply plenty free electrons which drastically enhances the optical and electrical properties compared to bulk material. Here, copper thin films have been deposited on glass slides and silicon substrates using an indigenously developed DC magnetron sputtering system. These depositions have been carried out at three different time spans keeping the magnetron discharge current, working vacuum and target to substrate distance unaltered. The objective of this work is to study the crystalline structure and measure the thickness of the copper nanofilm deposited at three different times. The synthesized films were characterized by using X-Ray Fluorescence (XRF), X-Ray Diffractometer (XRD) and Secondary Ion Mass Spectrometer (SIMS). Characteristic peaks of copper (111) along with Cu2O (110), (220) and (111) were obtained from the XRD pattern. The average grain size of the deposited films has been calculated using Debye-Scherrer equation. The film thickness ranging from 80-160 nm for various time spans were measured from depth profile analysis using SIMS data.

“…It has monoclinic structure and exhibits many properties such as high thermal conductivity, stability, and photovoltaic performance. Owing to these versatile properties, CuO can be used in several diverse applications, including fabrication of optoelectronic devices (Yu et al, 2016), heterogeneous catalysts (Chary et al, 2005), selective gas sensors (Samarasekara et al, 2006, Nayan et al, 2016, and solar cells (Chang et al, 2011, Shabu et al, 2015, Kidowaki et al, 2012. Up to now, CuO thin films have been synthesized using a variety of deposition techniques (Morales et al, 2005, Lim et al, 2014, Koh et al, 2013, Chen et al, 2009, Nair et al, 1999, Balamurugan et al, 2001, Mageshwari et al, 2013.…”

Nanostructured copper oxide thin films were fabricated on glass substrates at room temperature by a facile and costefficient Successive Ionic Layer Adsorption and Reaction (SILAR) method with varied amounts of polyethylene glycol (PEG). The effects of PEG on the optical properties of the CuO thin films were investigated by means of ultravioletvisible (UV-Vis) spectroscopy analysis. By UV-Vis analysis at the room temperature, it was seen that the optical band gap values and transmission characteristics of the CuO thin films vary with the increasing PEG concentration in the growth solution. The optical band gap energy of the CuO thin films was found to increase from 1.30 eV to 1.42 eV with the increasing PEG concentration. The thickness of the CuO thin films was also found to vary in between 137 nm and 680 nm depending on the PEG concentration. Other significant parameters including refractive index (n), high frequency dielectric constant () and optical static (0) values of the thin films were calculated by using the optical band gap energy values as a function of the film thickness. The investigations revealed that the PEG concentration has a remarkable impact on the optical properties of SILAR grown CuO thin films.
